MM74HC4060M集成电路（IC）的计数器除法器规格书PDF中文资料

General Description

The MM74HC4060 is a high speed binary ripple carry counter. These counters are implemented utilizing advanced silicon-gate CMOS technology to achieve speed performance similar to LS-TTL logic while retaining the low power and high noise immunity of CMOS.

The MM74HC4060 is a 14-stage counter, which device increments on the falling edge (negative transition) of the input clock, and all their outputs are reset to a low level by applying a logical high on their reset input. The MM74HC4060 also has two additional inputs to enable easy connection of either an RC or crystal oscillator.

This device is pin equivalent to the CD4060. All inputs are protected from damage due to static discharge by protection diodes to VCC and ground.
