Description

The CD54AC574/3A and CD54ACT574/3A are octal D-type,
three-state, positive-edge triggered flip-flops that utilize the
Harris Advanced CMOS Logic technology. The eight flip­flops 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 CD54AC574/3A
and CD54ACT574/3A are non-inverted.

The CD54AC574/3A and CD54ACT574/3A are supplied in
20 lead dual-in-line ceramic packages (F suffix).
