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.
