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. Noninverting Buffers Bidirectional Data Path A and B Outputs Source/Sink 24 mA ′ACT245 Has TTL Compatible Inputs
