DESCRIPTION
The AC161 is a high-speed CMOS SYNCRONOUS PRESETTABLE COUNTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.It is ideal for low power applications mantaining high speed operation similar to eqivalent Bipolar Schottky TTL. It is a 4 bit binary counter with Asynchronous Clear.
