54FCT245

Octal Bidirectional Transceiver with TRI-STATE^®Outputs

General Description

Features

n TTL input and output level compatible

n A and B output sink capability of 48 mA, source

capability of 12 mA

The ’FCT245 contains eight non-inverting bidirectional buff-

ers with TRI-STATE outputs and is intended for bus-oriented

applications. Current sinking capability is 48 mA on both the

A and B ports. The Transmit/Receive (T/R) input determines

the direction of data flow through the bidirectional trans-

ceiver. Transmit (active HIGH) enables data from A ports to B

ports; Receive (active LOW) enables data from B ports to A

ports. The Output Enable input, when HIGH, disables both A

and B ports by placing them in a High Z condition.
