MM74HC4040SJ

Counter Dividers Overview

The MM74HC4040SJ is a 12-stage binary ripple carry counter implemented with silicon-gate CMOS technology. It increments on the falling edge of the input clock and resets outputs to low via a high-level reset input. The device operates within a supply voltage range of 2V to 6V, supporting a maximum operating frequency of 50 MHz at 25°C. It features asynchronous reset functionality, negative edge triggering, and surface mount packaging in a 16-SOP format.

Counter Dividers Feature Summary

• High-speed binary counting utilizing advanced silicon-gate CMOS technology for LS-TTL compatible performance
• Asynchronous reset mechanism that clears all outputs to a low level upon receiving a logical high signal
• Negative edge triggered incrementing synchronized with the falling transition of the input clock
• Integrated static discharge protection diodes connected to VCC and ground across all inputs

Counter Dividers Applications

• Digital timing and sequencing circuits requiring precise stage counting
• Frequency division applications utilizing the ripple carry output stages
• General-purpose digital logic systems needing wide voltage operation compatibility

Counter Dividers Procurement Notes

Verify component authenticity through authorized distribution channels as this part number may be obsolete. Confirm package specifications match the 16-Lead Small Outline Package (SOP) EIAJ TYPE II standard. Review datasheet electrical characteristics for specific temperature and voltage conditions relevant to your design requirements before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a 12-stage binary counter is required with negative edge triggering capabilities. Ensure the application environment supports the specified operating temperature range of -40°C to +85°C. Verify that the system power supply remains within the 2V to 6V operational limits to maintain guaranteed propagation delay and frequency performance metrics.

Counter Dividers Part Context

This device belongs to the MM74HC series of high-speed CMOS logic components manufactured by Fairchild Semiconductor, now associated with onsemi. It serves as a functional equivalent to the CD4040 standard. The MM74HC4040SJ specifically denotes the SOP package variant, distinguishing it from SOIC or PDIP versions within the same logic family.

Counter Dividers Replacement Considerations

The MM74HC4040MTC offers a TSSOP package alternative. The MM74HC4040N provides a PDIP option. These variants maintain identical logic functions but differ in physical footprint and mounting style.
