M74HC193 SYNCHRONOUS UP/DOWN BINARY COUNTER

The M54/74HC192/193 are ahigh speed CMOSSYNCHRONOUS UP/DOWN DECADE COUNTERS fabricated in silicon gate C2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption. The counter has two separate clock inputs, an UP COUNT input and a DOWN COUNT inp.
