SN74LV4040APW

Counter Dividers Overview

The SN74LV4040APWR 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 function. It is housed in a 16-TSSOP package with a width of 4.40 mm, designed for surface-mount installation. The component functions reliably across an extended industrial temperature range from -40°C to +85°C.

Counter Dividers Feature Summary

• Provides twelve distinct output stages for binary counting applications
• Supports high-speed operation with a maximum counting frequency of 95 MHz
• Features asynchronous reset capability for immediate state control

Counter Dividers Applications

• Digital timing circuits requiring precise interval measurement
• Frequency division networks in signal processing systems
• Address generation logic in memory addressing schemes

Counter Dividers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Confirm RoHS3 compliance status through current datasheets. Check for any Product Change Notifications regarding marking or material updates before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a single 12-bit asynchronous counter is required. Ensure the design accommodates the 2 V to 5.5 V operating range. Verify that the 16-TSSOP footprint matches the PCB layout constraints. Consider the 95 MHz limit for high-frequency clock applications.

Counter Dividers Part Context

This part belongs to the SN74LV4040A family of 12-bit asynchronous binary counters. It shares functional characteristics with other members of the LV-A logic series but differs in packaging and suffix codes. The APWR designation specifically indicates the TSSOP-16 surface-mount variant.

Counter Dividers Replacement Considerations

The SN74LV4040APWT is listed as a discontinued equivalent. Verify availability of active alternatives such as the SN74LV4040AN for through-hole requirements if surface-mount options are insufficient.
