74ACT245 Octal Bidirectional Transceiver with 3-STATE Inputs/Outputs PDIP-20 (Made in Taiwan)
The AC/ACT245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended forbus-oriented applications. Current sinking capability is 24mA 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 (activeLOW) 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.
Features
- ICC and IOZ reduced by 50%.
- Non-inverting buffers.
- Bidirectional data path.
- A and B outputs source/sink 24mA.
- ACT245 has TTL-compatible inputs.
