74F545 Octal Bidirectional Transceiver with 3-STATE Outputs
April 1988
Revised August 1999
74F545
Octal Bidirectional Transceiver with 3-STATE Outputs
General Description
The 74F545 is an 8-bit, 3-STATE, high-speed transceiver. It
provides bidirectional drive for bus-oriented microproces-
sor and digital communications systems. Straight through
bidirectional transceivers are featured, with 24 mA bus
drive capability on the A Ports and 64 mA bus drive capa-
bility on the B Ports.
One input, Transmit/Receive (T/R) determines the direction
of logic signals through the bidirectional transceiver. Trans-
mit enables data from A-to-B Ports; Receive enables data
from B-to-A Ports. The Output Enable input disables both A
and B Ports by placing them in a 3-STATE condition.
