M54HC4024 Datasheet | STMicroelectronics

SCRIPTION The M54/74HC4024 is a high speed CMOS 7STAGE BINARY COUNTER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL bined with true CMOS low power consumption. The HC4024 is a 7 stage Counter. This devices is incremented on the falling edge (negative transition) of the input clock, and all its outputs are reset to a low level by applying a logical high on their reset input. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
