OCTAL BIDIRECTIONAL
TRANSCEIVER WITH
3-STATE INPUTS/OUTPUTS
The MC54/74F245 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/Re-
ceive (T/R) input determines the direction of data flow through the bidirectional
transceiver. Transmit (active HIGH) enables data from A ports to B ports; Re-
ceive (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.
• Noninverting Buffers
• Bidirectional Data Path
• B Outputs Sink 64 mA
• ESD > 4000 Volts
