description

This octal bus transceiver and register is designed for 1.65-V to 3.6-V V

operation.

The SN74LVC2952A consists of two 8-bit back-to-back registers that store data flowing in both directions

between two bidirectional buses. Data on the A or B bus is stored in the registers on the low-to-high transition

of the clock (CLKAB or CLKBA) input, provided that the clock-enable (CLKENAB or CLKENBA) input is low.

Taking the output-enable (OEAB or OEBA) input low accesses the data on either port.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators

in a mixed 3.3-V/5-V system environment.

To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN74LVC2952A is characterized for operation from –40°C to 85°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

testing of all parameters.
