Octal Bidirectional Transceiver with 3-State Inputs/Outputs

Key Features

• Noninverting Buffers

• Bidirectional Data Path

• A and B Outputs Source/Sink 24 mA

• ACT245 Has TTL Compatible Inputs

• Pb-Free Packages are Available

Description

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/Rbar) 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.
