General Description  
Features  
Y
Higher drive than 8304  
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 bidi-  
rectional 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.

TRI-STATE inputs/outputs for interfacing with bus-ori-  
ented systems  
24 mA (20 mA Mil) and 64 mA (48 mA Mil) bus drive  
capability on A and B ports, respectively  
Transmit/Receive and Output Enable simplify control  
logic  
One input, Transmit/Receive (T/R) determines the direction  
of logic signals through the bidirectional transceiver. Trans-  
mit enables data from A ports to B ports; Receive enables  
data from B ports to A ports. The Output Enable input dis-  
ables both A and B ports by placing them in a TRI-STATE  
condition.
