Product Summary
The tc74hc393af is a high speed CMOS 4-BIT BINARY COUNTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The tc74hc393af contains two independent counter circuits in one package, so that counting or frequency division of eight binary bits can be achieved with one IC.
