SN74ABT2952A
SN74ABT2952A is OCTAL BUS TRANSCEIVERS/REGISTERS manufactured by Texas Instruments.
description
The ’ABT2952A transceivers consist 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.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABT2952A is characterized for operation over the full military temperature range of
- 55°C to 125°C. The SN74ABT2952A is characterized for operation from
- 40°C to 85°C.
