MC74AC245, MC74ACT245

Octal Bidirectional

Transceiver with 3-State

Inputs/Outputs

The MC74AC245/74ACT245 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.
