4-BIT SYNCHRONOUS UP/DOWN COUNTERS

M74HC191 General Description

s The M74HC191 is an high speed CMOS 4-BIT b SYNCHRONOUS UP/DOWN COUNTER O fabricated with silicon gate C2MOS technology. - State changes of the counter are synchronous t(s) with the LOW-to-HIGH transition of the Clock Pulse Input. c An asynchronous parallel load input overrides u counting and loads.
