Positive-Edge Triggered, Non-Inverting Description The CD54AC374/3A and CD54ACT374/3A are octal D-type, three-state, positive-edge triggered ip-ops that utilize the Harris Advanced CMOS Logic technology. The eight ipops enter data into their registers on the LOW-to-HIGH transition of the clock (CP). The Output Enable (OE) controls the three-state outputs and is independent of the register operation. When the Output Enable (OE) is HIGH, the outputs are in the high-impedance state. The CD54AC374/3A and CD54ACT374/3A are supplied in 20 lead dual-in-line ceramic packages (F sufx).
