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.

CIN CPD
Input Capacitance Power Dissipation Capacitance (note 1)
1) 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 operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/2 (per COUNTER)
