The M54/74HCT160, 161, 162 and 163 are high speed CMOS SYNCHRONOUS PRESETTABLE COUNTERS fabricated with silicon gate C2MOS technology. They have the same high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

■ HIGH SPEED fMAX = 50 MHz (TYP.) AT VCC = 5 V

■ LOW POWER DISSIPATION ICC = 4 μA (MAX.) AT 25 °C

■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

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

■ COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN.); VIL = 0.8V (MAX.)

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS160 ～ 163
