SN74LV4040APWT

Counter Dividers Overview

The SN74LV4040APWT is a 12-bit asynchronous binary counter from the Texas Instruments 74LV series. It operates on a single supply voltage ranging from 2 V to 5.5 V and features negative-edge-triggered flip-flops with an up-counting sequence. The device supports a maximum counting rate of 95 MHz and includes an asynchronous reset function. It is housed in a 16-TSSOP package and is rated for operation within a temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Asynchronous 12-bit binary counting with up-sequence logic
• Negative-edge-triggered flip-flop architecture
• Wide operating voltage range supporting 2 V to 5.5 V supplies
• High-speed performance with a 95 MHz counting rate

Counter Dividers Applications

• Digital frequency division circuits
• Binary timing and sequencing control systems
• Event counting applications in embedded hardware
• Address generation in memory interfacing

Counter Dividers Procurement Notes

Verify the specific suffix 'PWT' against current manufacturer documentation, as this variant may be obsolete or subject to production lifecycle changes. Confirm availability through authorized distributors and check for active replacement recommendations if the component is no longer in production. Ensure the source provides valid RoHS compliance data and matches the 16-TSSOP package specifications.

Counter Dividers Selection Notes

Select this component when a high-speed, wide-voltage asynchronous binary counter is required. The 74LV series offers compatibility with standard logic levels while supporting lower voltage operations down to 2 V. Consider the 16-TSSOP package for surface-mount designs requiring compact footprints. Verify that the asynchronous reset requirement aligns with the system timing constraints.

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 74LV series, such as the SN74LV4040APWR, which uses a TSSOP-16 package. The 'PWT' suffix typically indicates a tape-and-reel packaging format intended for automated assembly processes.

Counter Dividers Replacement Considerations

The SN74LV4040APWR is a verified equivalent part number offering identical electrical specifications and functionality in a compatible TSSOP-16 package. Check for any minor differences in packaging or marking before substitution.
