Description

The HD74AC245/HD74ACT245 contains eight non-inverting bidirectional buffers with 3-state outputs and is intended

for bus-oriented applications. Current sinking capability is 24 mA at both the A and 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 Enable input,

when High, disables, both A and B ports by placing them in a High Z condition.

Features

• Noninverting Buffers

• Bi-directional Data Path

• A and B Outputs Source/Sink 24 mA

• HD74ACT245 has TTL-Compatible Inputs

• Ordering Information: Ex. HD74AC245
