SN74ABT657A Datasheet (Texas Instruments)

SN74ABT657A, OCTAL TRANSCEIVERS

The 'ABT657A transceivers have eight noninverting buffers with parity-generator/ checker circuits and control signals.

The transmit/receive (T/R) input determines the direction of data flow.

When T/R is high, data flows from the A port to the B port (transmit mode); when T/R is low, data flows from
