DESCRIPTION

The M74HC4520 is an high speed CMOS DUAL

BINARY COUNTER fabricated with silicon gate

C2MOS technology.

It consists of two identical internally synchronous

4-stage counters. The counter stages are D-TYPE

flip-flops having interchangeable CLOCK and

ENABLE inputs for incrementing on either the

positive-going or negative-going transition.

For single-unit operation the ENABLE input is

maintained "high" and the counter advances on

each positive-going transition of the CLOCK. The

counters are cleared by high levels on their clear

lines.

The counter can be cascaded in the ripple mode

by connecting Q4 to the enable input of the

subsequent counter while the clock input of the

latter is held permanently low.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
