74HCT4040N,652

Counter Dividers Overview

The 74HCT4040N,652 is a 12-stage binary ripple counter manufactured by NXP USA Inc. It features a clock input (CP), an overriding asynchronous master reset input (MR), and twelve parallel outputs (Q0 to Q11). The counter advances on the HIGH-to-LOW transition of CP. A HIGH signal on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. Each stage utilizes a static toggle flip-flop with clamp diodes for input protection. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C.

Counter Dividers Feature Summary

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Procurement Notes

Verify the specific ordering suffix '652' against current Nexperia or NXP documentation to confirm package type and availability status. Confirm that the DIP16 plastic dual in-line package matches the design requirements. Ensure compliance with RoHS directives as indicated in the product specifications before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a 12-stage binary counting function is required with TTL-compatible input levels. The HCT variant ensures compatibility with standard 5V logic systems. Verify that the DIP16 through-hole package fits the PCB layout constraints. Consider the maximum operating frequency limits under the specific load capacitance conditions defined in the dynamic characteristics table.

Counter Dividers Part Context

This part belongs to the 74HC/HCT4040 family of 12-stage binary ripple counters. It shares functional similarities with other members like the 74HC4040 but differs in input voltage thresholds to support TTL interfaces. The NXP Semiconductors portfolio includes various package options such as SO16, SSOP16, and TSSOP16 for this logical function.

Counter Dividers Replacement Considerations

The 74HC4040N serves as a CMOS-level alternative within the same family. Other package variants like the 74HCT4040D (SO16) or 74HCT4040DB (SSOP16) offer pin-compatible replacements if surface-mount technology is preferred over the DIP16 form factor.
