MC74ACT245
Octal Bidirectional Transceiver
with 3ĆState 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.
• Noninverting Buffers
• Bidirectional Data Path
• A and B Outputs Source/Sink 24 mA
• ′ACT245 Has TTL Compatible Inputs
