SN74HC4040NSR TI 12-Bit Ripple Counter | 16-SO | 2V-6V, 36MHz

Product Overview

The SN74HC4040NSR from Texas Instruments is a high-speed 12-stage binary ripple counter with a 12-bit parallel output. It is designed for use in 2V to 6V systems and offers a typical clock frequency of 36MHz. The device features an asynchronous master reset (MR) input that clears all stages and sets all outputs low. The counter advances on the negative-going edge of the clock (CP) input. This device is ideal for frequency division, time delay generation, and event counting in a wide range of digital applications.
