MM74HC164 — 8-Bit Serial-in/Parallel-out Shift Register
DC Electrical Characteristics
(3)
Note:
3. For a power supply of 5V ±10% the worst case output voltages (V
OH
, and V
OL
) occur for HC at 4.5V. Thus the 4.5V
values should be used when designing with this supply. Worst case V
IH
and V
IL
occur at V
CC
=
5.5V and 4.5V
respectively. (The V
IH
value at 5.5V is 3.85V.) The worst case leakage current (I
IN
, I
CC
, and I
OZ
) occur for CMOS at
the higher voltage and so the 6.0V values should be used.
