SN54ABT2952A Datasheet OCTAL BUS TRANSCEIVERS/REGISTERS

Manufacturer: Texas Instruments

General 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.
