The A15 16 33 B15 low on-state resistance of the switch allows A16 17 32 B16 connections to be made with minimal propagation A17 18 31 B17 delay. A18 19 30 B18 The device can be used as a 22-bit switch, with the A19 20 29 B19 gates cascaded together to a reference transistor. A20 21 28 B20 The low-voltage side of each pass transistor is A21 22 27 B21 limited to a voltage set by the reference transistor. A22 23 26 B22 This is done to protect components with inputs A23 24 25 B23 that are sensitive to high-state voltage-level overshoots. (See Application Information in this data sheet.) All of the transistors in the TVC array have the same electrical characteristics; therefore, any one of them can be used as the reference transistor. Because, within the device, the characteristics from transistor to transistor are equal, the maximum output high-state voltage (V ) is approximately the reference voltage (V ), with OH REF minimal deviation from one output to another. This is a benefit of the TVC solution over discrete devices. Because the fabrication of the transistors is symmetrical, either port connection of each bit can be used as the low-voltage side, and the I/O signals are bidirectional through each FET.

These standards define, among other things, the I/O voltage levels at which the bus communicates. Examples include the GTL+ host bus, the AGP graphics port, and the PCI local bus. In new designs, the system components must communicate with existing bus infrastructure. Providing an evolutionary upgrade path is important in the design of PC architecture, but the existing bus standards must be preserved. To achieve the ever-present need for smaller, faster, lighter devices that draw less power, yet have faster performance, most new high-performance digital integrated circuits are designed and produced with advanced submicron semiconductor process technologies. These devices have thin gate-oxide or short channel lengths and very low absolute-maximum voltages that can be tolerated at the inputs/outputs (I/Os) without causing damage. In many cases, the I/Os of these devices are not tolerant of the high-state voltage levels on the preexisting buses with which they must communicate. Therefore, it became necessary to protect the I/Os of devices by limiting the I/O voltages. The Texas Instruments (TI) translation voltage-clamp (TVC) family is designed specifically for protecting sensitive I/Os (see Figure 2). The information in this data sheet describes the I/O-protection application of the TVC family and should enable the design engineer to successfully implement an I/O-protection circuit utilizing the TI TVC solution.

This connection determines the V input of the reference transistor. The BIAS V input is connected through a pullup resistor (typically 200 kΩ ) to the V supply. A filter capacitor on V BIAS DD BIAS is recommended. The opposite side of the reference transistor is used as the reference voltage (V ) REF connection. The VREF input must be less than VDDREF − 1 V to bias the reference transistor into conduction. The reference transistor regulates the gate voltage (V ) of all the pass transistors. V is determined by GATE GATE the characteristic gate-to-source voltage difference (VGS) because VGATE = VREF + VGS. The low-voltage side of the pass transistors has a high-level voltage limited to a maximum of VGATE − VGS, or VREF.

Figure 4 shows the test configuration for the TI SPICE simulations. The results, shown in Figures 5 and 6, show the current through a pass transistor versus the voltage at the source for different reference voltages. The plots of the dc characteristics clearly reveal that the device clamps at the desired reference voltage for the varying device environments. Figure 5 shows the V-I characteristics with low reference voltages and a reference-transistor drain-supply voltage of 3.3 V. To further investigate the spread of the V-I characteristic curves, V was held at 2.5 V and REF I was increased by raising V (see Figure 6). The result was a tighter grouping of the V-I curves.

Table 1 lists these features and their associated benefits. Table 1. Features and Benefits FEATURES BENEFITS Any FET can be used as the reference transistor. Ease of layout All FETs on one die, tight process control Very low spread of VO relative to VREF No active control logic (passive device) No logic power supply (VCC) required Flow-through pinout Ease of trace routing Devices offered in different bit widths and packages Optimizes design and cost effectiveness Designer flexibility with VREF input Allows migration to lower-voltage I/Os without board redesign conclusion The TI TVC family provides the designer with a solution for protection of circuits with I/Os that are sensitive to high-state voltage-level overshoots. The flexibility of TVC enables a low-voltage migration path for advanced designs to align with industry standards. frequently asked questions (FAQs) 1. Q: Can any of the transistors in the array be used as the reference transistor? A: Yes, any transistor can be used as long as its V pin is connected to the GATE pin. BIAS 2. Q: In the recommended operating conditions table of the data sheet, the typical V is 3.3 V. BIAS Should V be equal to or greater than V on the reference transistor? BIAS REF A: V is a variable that is determined by V . V is connected to V through a resistor to allow the BIAS REF BIAS DD bias voltage to be controlled by V . V can be as high as 5.5 V. V needs to be at least 1 V less REF DD REF than V on the reference transistor. DDREF 3. Q: Do both A and B ports have 5-V I/O tolerance or is 5-V I/O tolerance provided only on the low-voltage side? A: Both ports are 5-V tolerant. 10 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265
