GULL WING DUAL POSITIVE EDGE UP divider circuit 50pF 125C 25MHz 5V

SYNCHRONOUS PRESETTABLE 4-BIT COUNTER

Counter ICs SO-16 SYNC BIN CNTR

The M74HC161 is an high speed CMOSSYNCHRONOUS 4-BIT BINARY PRESETTABLE COUNTER fabricated with silicon gate C2MOS technology. The CLOCK input is active on the rising edge. Both LOAD and CLEAR inputs are active LOW. Presetting is synchronous on the rising edge of the clock, the function is cleared asynchronously. Two enable inputs (TE and PE) and Carry output are provided to enable easy cascading of counters, which facilities easy implementation of N-bit counters without using external gates. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
