74HC393D Datasheet | Toshiba

CMOS Digital Integrated Circuits Silicon Monolithic 1. Functional Description - Dual Binary Counter 2. General The 74HC393D 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. It contains two independent counter circuits in one package, so that counting or frequency division of eight binary bits can be achieved with one IC. This device changes state on the negative going transition of the CK pulse. The counter can be reset to "0" (QA to QD = "L") by a high at the CLR input regardless of other inputs. All inputs are...
