SN74LV4040AD

Counter Dividers Overview

The SN74LV4040AD 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 supports a maximum counting rate of 95 MHz. The device utilizes negative-edge-triggered flip-flops for up-counting operations and features an asynchronous reset input. It is housed in a 16-pin SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

Counter Dividers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and electrical characteristics. Ensure compatibility with system voltage levels and thermal requirements before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status based on current manufacturing revisions.

Counter Dividers Selection Notes

Select this component when a single 12-bit counter is required rather than cascading smaller units. Consider the LV-A logic family for low voltage operation and reduced power consumption compared to standard CMOS alternatives. Evaluate the SOIC package constraints against available PCB real estate and thermal dissipation needs.
