74F545  
Octal Bidirectional Transceiver with 3-STATE Outputs  
General Description  
Features  
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.  
Higher drive than 8304  
8-bit bidirectional data flow reduces system package  
count  
3-STATE inputs/outputs for interfacing with bus-oriented  
systems  
24 mA and 64 mA bus drive capability on A and B Ports,  
respectively  
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.  
Transmit/Receive and Output Enable simplify control  
logic  
Guaranteed 4000V minimum ESD protection
