DESCRIPTION
The M54/74HC190/191 are high speed CMOS4-BIT
SYNCHRONOUS UP/DOWN COUNTERS fabri-
cated in silicon gate C2MOS technology.
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-
cuitsasprogrammable counters. Acountenable 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-
putand a RippleClockoutput provide overflow/under-
flow indication and make possible a variety of
methods for generating carry/borrow signals in multi-
stage counter applications.
NC =
No Internal
Connection
Allinputs are equipped with protection circuits against
static discharge and transient excess voltage.

(*) CPD isdefined 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 operting current can be obtained by the followingequation. ICC(opr) = CPD • VCC • fIN + ICC
