74HC691, 74HC690, (74HC690 - 74HC693) 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
