DESCRIPTION
The M54/74HC4518/4520 are high speed CMOS DUAL 4 BIT BINARY COUNTERS fabricated in silicon gate C2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption.

.HIGH SPEED
  fMAX= 55 MHz (TYP.) at VCC=5V
.LOW POWER DISSIPATION
  ICC=4µA (MAX.) AT TA=25°C
.HIGH NOISE IMMUNITY
  VNIH=VNIL=28%VCC(MIN.)
.OUTPUT DRIVE CAPABILITY
  10 LSTTL LOADS
.SYMMETRICAL OUTPUT IMPEDANCE
  |IOH|=IOL= 4 mA (MIN.)
.BALANCED PROPAGATION DELAYS
  tPLH=tPHL
.WIDE OPERATING VOLTAGE RANGE
  VCC(OPR) = 2 V TO 6 V
.PIN AND FUNCTION COMPATIBLE WITH 4520B/4518B
