M74HC4020 - HC4020 14 STAGE BINARY COUNTER
The M54/74HC4020/HC4040 are high speed CMOS 14/12-STAGE BINARY COUNTER fabricated in silicon gate C2MOS technology.
They have the same high speed performance of LSTTL combined with true CMOS low consumption.
A clear input is used to reset the counter to the all low level state.
