OCTAL BIDIRECTIONAL TRANSCEIVER WITH TRI-STATE OUTPUTS
General Description
The F545 is an 8-bit, TRI-STATE, high-speed transceiver. It provides bidirectional drive
for bus-oriented mICroprocessor and digital communications systems. Straight through
bidirectional transceivers are featured, with 24 mA (20 mA Mil) bus drive capability on
the A ports and 64 mA (48 mA Mil) bus drive capability on the B ports.
One input, Transmit/Receive (T/R) determines the direction of logic signals through the
bidirectional transceiver. Transmit enables data from A ports to B ports; Receive enables
data from B ports to A ports. The Output Enable input disables both A and B ports by
