SN74LV4040ANSR

Counter Dividers Overview

The SN74LV4040ANSR is a 12-bit asynchronous binary counter from the Texas Instruments SN74LV4040A series. It operates within a supply voltage range of 2 V to 5.5 V and features negative-edge triggering for each flip-flop stage. The device utilizes high-speed CMOS technology, enabling operation across an extended temperature range from -40°C to +85°C. It is housed in a 16-pin TSSOP package with surface-mount installation. The logic type supports upward counting sequences with asynchronous reset functionality.

Counter Dividers Feature Summary

• Provides 12-bit asynchronous binary counting capability using negative-edge triggered flip-flops
• Operates on a wide supply voltage range from 2 V to 5.5 V for flexible system integration
• Features asynchronous reset function to clear all counter stages independently of the clock signal

Counter Dividers Applications
