Description 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.) The CD54AC245/3A and CD54ACT245/3A are supplied in 20 lead dual-in-line ceramic packages (F sufx). ACT INPUT LOAD TABLE A7 INPUT An, Bn OE DIR NOTE: UNIT LOAD (NOTE 1) 0.83 0.64 0.15 DIR OE 19 1.
