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 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.
