DESCRIPTION
The M54/74HC190/191 are high speed CMOS 4-BIT
SYNCHRONOUS UP/DOWN COUNTERS fabri-
cated in silicon gate C
They have the same high speed performance of
LSTTL combined with true CMOS low power con-
sumption.
State changes of the counter are synchronous with
the LOW-to-HIGH transition of the Clock Pulse input.
An asynchronous parallel load input overrides count-
ing and loads the data present on the DATA inputs into
the flip-flops, which makes it possible to use the cir-
cuits as programmable counters. A countenable input
serves as the carry/borrow input in multi-stage
counters. Control input, Down/Up, determines
whether a circuit counts up or down. A MAX/MIN out-
put and a Ripple Clock output provide overflow/under-
flow indication and make possible a variety of
methods for generating carry/borrow signals in multi-
stage counter applications.
All inputs are equipped with protection circuits against
static discharge and transient excess voltage.
