HD74AC245/HD74ACT245
Octal Bi-directional Transceiver with 3-State Input/Output
REJ03D0263–0200Z
(Previous ADE-205-384 (Z))
Rev.2.00
Jul.16.2004
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
