OCTAL BIDIRECTIONAL

TRANSCEIVER WITH 8-BIT PARITY

GENERATOR CHECKER

(3-STATE OUTPUTS)

The MC74F657A and MC74F657B are Octal Bidirectional Transceivers

with an 8-bit parity Generator/Checker and 3-state outputs.

The A and B options are faster versions of the F657 and contain eight non-

inverting buffers with 3-state outputs and an 8-bit parity generator/checker.

These devices are intended for bus-oriented applications. The buffers have

a guaranteed current sinking capability of 24 mA at the A ports and 64 mA at

the B ports. The Transmit/Receiver (T/R) input determines the direction of the

data flow through the bidirectional transceivers. Transmit (active HIGH) en-

ables data from A ports to B ports; Receive (active LOW) enables data from

B ports to A ports.
