TC74HC390AF Dual Decade Counter

TC74HC390AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC390AP, TC74HC390AF Dual Decade Counter The TC74HC390A is a high speed CMOS DUAL DECADE COUNTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. It consists of two independent 4-bit counters, each composed of a divide-by-two and a divide-by-five counter. The divide-by-two counter is incremented on the nega.
