Octal Bidirectional Transceiver With TRI-State
Inputs/Outputs
General Description
The ACT245 contains eight non-inverting bidirectional buffers with 3-state outputs and is
intended for bus-oriented applications. Current sinking capability is 24 mA at the A
ports and 24 mA at the B ports. The Transmit/Receiver (TR) 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.
