IC M74HC161

DESCRIPTION
The M74HC161 is an high speed CMOS
SYNCHRONOUS 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.

HIGH SPEED :
fMAX = 62 MHz (TYP.) at VCC = 6V
n LOW POWER DISSIPATION:
ICC =4mA(MAX.) at TA=25
