DESCRIPTION

The M74HC4520 is an high speed CMOS DUAL

BINARY COUNTER fabricated with silicon gate

C MOS technology.

each positive-going transition of the CLOCK. The

counters are cleared by high levels on their clear

lines.

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.

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.

For single-unit operation the ENABLE input is

maintained "high" and the counter advances on
