This 10-bit buffer has NANDed output-enable (OE) inputs for maximum control flexibility. The CY74FCT2827T is designed for high-capacitance-load drive capability, while providing low-capacitance bus loading at both inputs and outputs. All inputs have clamp diodes and all outputs are designed for low-capacitance bus loading in the high-impedance state. On-chip termination resistors at the outputs reduce system noise caused by reflections. The CY74FCT2827T can replace the CY74FCT827T to reduce noise in an existing design. This device is fully specified for partial-power-down applications using I . The I circuitry disables the outputs, off off preventing damaging current backflow through the device when it is powered down.

Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample-and-hold techniques are preferable to minimize internal chip heating and more accurately reflect operational values. Otherwise, prolonged shorting of a high output can raise the chip temperature well above normal and cause invalid readings in other parametric tests. In any sequence of parameter tests, IOS tests should be performed last. §Per TTL-driven input (VIN = 3.4 V); all other inputs at VCC or GND ¶This parameter is derived for use in total power-supply calculations. #IC = ICC + ∆ICC × DH × NT + ICCD (f0/2 + f1 × N1) Where: IC = Total supply current ICC = Power-supply current with CMOS input levels ∆ICC = Power-supply current for a TTL high input (VIN = 3.4 V) DH = Duty cycle for TTL inputs high NT = Number of TTL inputs at DH ICCD = Dynamic current caused by an input transition pair (HLH or LHL) f0 = Clock frequency for registered devices, otherwise zero f1 = Input signal frequency N1 = Number of inputs changing at f1 All currents are in milliamperes and all frequencies are in megahertz. ||Values for these conditions are examples of the ICC formula.

Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
