Octal D-Type Flip-Flop, Three-State
Positive-Edge Triggered, Non-Inverting
Description
Functional Diagram
The CD54AC374/3A and CD54ACT374/3A are octal D-type,
three-state, positive-edge triggered flip-flops that utilize the
Harris Advanced CMOS Logic technology. The eight flip-
flops 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 out-
puts are in the high-impedance state.
The CD54AC374/3A and CD54ACT374/3A are supplied in
20 lead dual-in-line ceramic packages (F suffix).
