Octal Bidirectional Transceiver with TRI-STATE Outputs

General Description

Features

Non-inverting buffers

The ’F245 contains eight non-inverting bidirectional buffers

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

applications. Current sinking capability is 24 mA (20 mA Mil)

at the A ports and 64 mA (48 mA Mil) at the B ports. The

Transmit/Receive (T/R) input determines the direction of

data flow through the bidirectional transceiver. Transmit (ac-

tive 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.

Bidirectional data path

A outputs sink 24 mA (20 mA Mil)

B outputs sink 64 mA (48 mA Mil)

Guaranteed 4000V minimum ESD protection
