MM74HC4040MX

The MM74HC4040MX from On Semiconductor is a high-speed 12-stage binary ripple carry counter. It utilizes advanced silicon-gate CMOS technology to achieve performance comparable to LS-TTL logic while maintaining the low power consumption and high noise immunity characteristic of CMOS devices.

This counter increments on the falling edge of the input clock signal. A logical high on the reset input sets all outputs to a low level. Key electrical specifications include a wide operating voltage range of 2V to 6V, a typical propagation delay of 16ns, and a maximum count rate of 50 MHz. It also features low input current (1µA Max.) and low quiescent current (80µA Max.). The output drive capability is rated at 10 LS-TTL loads.

The MM74HC4040MX is supplied in a 16-SOIC surface mount package. It is designed for applications requiring counting or frequency division, such as digital frequency counters, pulse generators, time delay circuits, clock dividers, and general-purpose binary counting circuits. Its high-speed capabilities and low power consumption make it suitable for various digital logic applications.
