The CD54AC245/3A and CD54ACT245/3A are octal-bus
transceivers that utilize the Harris Advanced CMOS Logic
technology. They are non-inverting three-state bidirectional
tranceiver-buffers intended for two-way transmission from
“A” bus to “B” bus or “B” bus to “A” bus. 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.)
