M54HC390 DUAL DECADE COUNTER

The M54/74HC390 is a high speed CMOS DUAL DECADE COUNTER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. This dual decade counter contains two independent ripple carry counters. Each counter is composed of a .
