DESCRIPTION
The M54HC374 is an high speed CMOS OCTAL
D-TYPE FLIP FLOP WITH 3-STATE OUTPUTS
NON INVERTING fabricated with sub-micron
silicon gate C2MOS technology.
This 8 bit D-TYPE FLIP FLOP is controlled by a
clock input (CK) and an output enable input (OE).

On the positive transition of the clock, the Q
outputs will be set to the logic state that were
setup at the D inputs.
While the OE input is at low level, the eight outputs
will be in a normal logic state (high or low logic
level) and while OE is high the outputs will be in a
high impedance state.
The output control does not affect the internal
operation of flip-flops; that is, the old data can be
retained or the new data can be entered even
while the outputs are off.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/8 (per Flip
Flop) and the CPD when n pcs of Flip Flop operate, can be gained by the following equation: CPD(TOTAL) = 30 + 17 x n (pF)
