DESCRIPTION

The M74HC4520 is an high speed CMOS DUAL BINARY COUNTER fabricated with silicon gate C2MOS technology.

■ HIGH SPEED : fMAX = 60 MHz (TYP.) at VCC = 6V

■ LOW POWER DISSIPATION: ICC =4µA(MAX.) at TA=25°C

■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28 VCC (MIN.)

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 4520
