onsemi Counters, Dividers MM74HC4040MX

The MM74HC4040 is a 12-stage binary ripple carry counter designed using advanced silicon-gate CMOS technology. It operates within a voltage range of 2 to 6 volts and features a typical propagation delay of 16 nanoseconds. The device is incremented on the falling edge of the input clock and can be reset to a low level by applying a logical high to its reset input. It has low input and quiescent current specifications, with a maximum input current of 1 µA and a maximum quiescent current of 80 µA. The MM74HC4040 can drive up to 10 LS-TTL loads, making it suitable for various applications. It is available in multiple package types, including SOIC, SOP, TSSOP, and PDIP. All inputs are protected against static discharge, enhancing reliability in circuit designs.
