SN74LV4040ADR

Counter Dividers Overview

The SN74LV4040ADR is a 12-bit asynchronous binary counter from the Texas Instruments SN74LV4040A series. It operates on a single power supply ranging from 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 logic and features an asynchronous reset function. It is housed in a 16-pin SOIC package with a wide operating temperature range spanning from -40°C to +85°C.

Counter Dividers Procurement Notes

Verify the specific suffix 'ADR' against the manufacturer's official documentation to confirm the SOIC-16 package type and tape-and-reel delivery format. Ensure that the required voltage levels and signal integrity requirements align with the specified 2 V to 5.5 V operational range before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a high-speed, 12-bit asynchronous counting solution is required within standard CMOS logic families. It is suitable for designs needing a wide voltage tolerance and robust performance across industrial temperature ranges. Consider alternative synchronous counters if simultaneous output updates are necessary to avoid transient glitches.

Counter Dividers Part Context
