MC74F1245 OCTAL BIDIRECTIONAL TRANSCEIVER WITH 3-STATE INPUTS/OUTPUTS The MC74F1245 contains eight noninverting bidirectional buffers with 3-state outputs and is intended for bus-oriented applications.
Current sinking capability is 24 mA at the A 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
