M74HC693 HC691/693 4 BIT BINARY COUNTER/REGISTER

The HC690/691/692/693 are high speed CMOS COUNTER/REGISTER fabricated in silicon gate C2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption. The internal circuit is composed of 3 stages including buffer output, which offers high noise immu.
