SN74LV4040AD TI Counter IC | 16-SOIC | 12-Bit, 2V to 5.5V

Product Overview

The SN74LV4040AD from Texas Instruments is a 12-stage binary ripple counter with an asynchronous clear function. It is designed for low-voltage operation (2V to 5.5V) and features a high-speed performance typical of the LV family. The device counts in binary on the negative-going edge of the clock input, and the counter is cleared to zero by applying a high level on the clear input. The SN74LV4040AD is available in a 16-pin SOIC package, making it suitable for space-constrained applications.
