Description

The ’AC245 and ’ACT245 are octal-bus transceivers that

utilize Advanced CMOS Logic technology. They are non-

inverting

three-state

bidirectional

transceiver-buffers

intended for two-way transmission from “A” bus to “B” bus or

“B” bus to “A”. The logic level present on the direction input

(DIR) determines the data direction. When the output enable

input (OE) is HIGH, the outputs are in the high-impedance

state.
