HD74AC245/HD74ACT245
Octal Bidirectional Transceiver with 3-State Input/Output
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.
