74F245

Octal Bidirectional Transceiver with 3-STATE Outputs

Enable input, when HIGH, disables both A and B Ports by

placing them in a High Z condition.

General Description

The 74F245 contains eight non-inverting bidirectional buff-

ers with 3-STATE outputs and is intended for bus-oriented

applications. Current sinking capability is 24 mA at the A

Features

■ Non-inverting buffers

■ Bidirectional data path

■ A outputs sink 24 mA

■ B outputs sink 64 mA

Ports and 64 mA at the B Ports. The Transmit/Receive

(T/R) input determines the direction of data flow through

the bidirectional transceiver. Transmit (active HIGH)

enables data from A Ports to B Ports; Receive (active

LOW) enables data from B Ports to A Ports. The Output
