DESCRIPTION

The M74HC190 is an high speed CMOS 4-BIT

SYNCHRONOUS

UP/DOWN

COUNTER

MOS technology.

fabricated with silicon gate C

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

PIN CONNECTION AND IEC LOGIC SYMBOLS

-O

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.
