DESCRIPTION
The M74HC190 is an high speed CMOS 4-BIT
SYNCHRONOUS
UP/DOWN
COUNTER
fabricated with silicon gate C2MOS technology.
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
count enable 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 multi-stage counter
applications.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
