com MC74F657A,B 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 noninverting 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.
