.. TC74AC390P/F/FN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC390P,TC74AC390F,TC74AC390FN Dual Decade Counter Note: The TC74AC390 is an advanced high speed CMOS DUAL DECADE COUNTER fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It consists of two independent 4-bit counters, each posed of a divide-by-two and a divide-by-five counter. The divide-by-two counter is incremented on the negative going transition of clock A ( CKA ). The divided-by-five counter is incremented on the negative going...
