PI4ULS5V102 Principles of operation Applications The PI4ULS5V102 can be used in level-translation applications for interfacing devices or systems operating at different interface voltages with one another. Architecture The PI4ULS5V102 architecture (see Figure1) does not require a direction-control signal to control the direction of data flow from A to B or from B to A. In a dc state, the output drivers of the PI4ULS5V102 can maintain a high or low, but are designed to be weak, so that they can be overdriven by an external driver when data on the bus starts flowing the opposite direction. The output one shots detect rising or falling edges on the A or B ports. During a rising edge, the one shot turns on the PMOS transistors (T1, T3) for a short duration, which speeds up the low-to-high transition. Similarly, during a falling edge, the one shot turns on the NMOS transistors (T2, T4) for a short duration, which speeds up the high-to-low transition. The typical output impedance during output transition is 70 Ω at V =1.2 V to 1.8 V, 50 Ω at V =1.8 V to 3.3 V, and 40 Ω at V =3.3 V to 5 V. CCO CCO CCO Input Driver Requirements Typical I vs V characteristics of the PI4ULS5V102 are shown in Figure 2. For proper operation, the device driving the data IN IN I/Os of the PI4ULS5V102 must have drive strength of at least ±2mA. Power Up During operation, ensure that V ≤ V at all times. During power-up sequencing, VCCA ≥ VCCB does not damage the device, CCA CCB so any power supply can be ramped up first. The PI4ULS5V102 has circuitry that disables all output ports when either V is CC switched off (V = 0 V). CCA/B Enable and Disable The PI4ULS5V102 has an OE input that is used to disable the device by setting OE = low, which places all I/Os in the high-impedance (Hi-Z) state. The disable time (t ) indicates the delay between when OE goes low and when the outputs acutally dis get disabled (Hi-Z). The enable time (ten) indicates the amount of time the user must allow for the one-shot circuitry to become operational after OE is taken high. Pull-up or Pull-down Resistors on I/O Lines The PI4ULS5V102 is designed to drive capacitive loads of up to 70 pF. The output drivers of the PI4ULS5V102 have low dc drive strength. If pullup or pulldown resistors are connected externally to the data I/Os, their values must be kept higher than 50 kΩ to ensure that they do not contend with the output drivers of the PI4ULS5V102. For the same reason, the PI4ULS5V102 should not be used in applications such as I2C or 1-Wire where an open-drain driver is connected on the bidirectional data I/O.
