soDESCRIPTION
bThe M74HC533 is an high speed CMOS OCTAL
OLATCH WITH 3-STATE OUTPUTS fabricated
-with silicon gate C2MOS technology.
t(s)This 8-BIT D-Type latches is controlled by a latch
enable input (LE) and output enable input (OE).
cWhile the LE input is held at a high level, the Q
uoutputs will follow the data input. When the LE is
dtaken, the Q outputs will be latched at the logic
rolevel of D input data.

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 high level the outputs will be in a
high impedance state.
The 3-State output configuration and the wide
choice of outline make bus organized system
simple.
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) = 22 + 16 x n (pF)
