DESCRIPTION

The M54/74HCT393 is a high speed CMOS DUAL BINARY COUNTER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true COMS low power consumption.

■ HIGH SPEED fMAX = 80 MHz (TYP.) AT VCC = 5 V

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

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

■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS

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

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS393
