DESCRIPTION
The M54/74HC190/191 are high speed CMOS 4-BIT
SYNCHRONOUS UP/DOWN COUNTERS fabricated in silicon gate C2MOS technology.
They have the same high speed performance of
LSTTL combined with true CMOS low power consumption.
State changes of the counter are synchronous with
the LOW-to-HIGH transition of the Clock Pulse input.
An asynchronous parallel load input overrides counting and loads the data present on the DATA inputs into
the flip-flops, which makes it possible to use the circuits 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 output and a Ripple Clock output provide overflow/underflow indication and make possible a variety of
methods for generating carry/borrow signals in multistage counter applications.
All inputs are equipped with protection circuits against
static discharge and transient excess voltage.

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