SN74LV4040AN

Counter Dividers Overview

The SN74LV4040AN 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. The device counts in an upward direction and includes an asynchronous reset function. It is housed in a 16-pin PDIP package with through-hole mounting. The component supports a maximum counting rate of 95 MHz and functions within an operating temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Provides twelve distinct output stages for binary counting applications
• Utilizes asynchronous reset capability for immediate state clearing
• Supports wide voltage operation across standard logic levels

Counter Dividers Applications

• Digital frequency division circuits
• Event counting systems
• Timing sequence generation

Counter Dividers Procurement Notes

Verify the specific package type, as the SN74LV4040A family includes surface-mount variants like APWR. Confirm RoHS compliance status and check for active manufacturing status versus obsolescence notices. Ensure the supplier provides official datasheets matching the exact suffix to guarantee pinout and electrical parameter accuracy.

Counter Dividers Selection Notes

Select this component when a high-speed, 12-bit asynchronous counter is required in a through-hole format. Compare against synchronous alternatives if simultaneous output switching is critical. Verify that the 95 MHz speed rating meets system timing requirements and that the 2 V to 5.5 V supply range aligns with the target power architecture.

Counter Dividers Part Context

This part belongs to the SN74LV4040A family of 12-bit asynchronous binary counters. It shares functional similarities with other 74LV series logic devices but is distinguished by its specific bit depth and asynchronous nature. The AN suffix denotes the PDIP package variant, differing from surface-mount options like APWR or APWT.

Counter Dividers Replacement Considerations

SN74LV4040APWR offers identical functionality in a TSSOP-16 surface-mount package. SN74HC4040 provides similar performance in the HC series with different drive characteristics.
