MM74HC4040MTCX

Counter Dividers Overview

The MM74HC4040MTCX is a 12-stage binary ripple carry counter implemented using advanced silicon-gate CMOS technology. It operates within a supply voltage range of 2 V to 6 V and functions in an ambient temperature range of -40 °C to +85 °C. The device increments on the falling edge of the input clock and resets outputs via a logical high signal. It features a maximum operating frequency of 30 MHz at 4.5 V and typical propagation delays of 16 ns. The component utilizes a 16-lead Thin Shrink Small Outline Package (TSSOP) with JEDEC MO-153 specifications.

Counter Dividers Feature Summary

• Advanced silicon-gate CMOS implementation for high-speed performance comparable to LS-TTL logic
• Asynchronous reset capability that forces all outputs to a low level upon receiving a logical high signal
• Integrated protection diodes on all inputs to prevent damage from static discharge events

Counter Dividers Applications

• High-speed binary counting applications requiring TTL-compatible noise immunity
• Frequency division circuits utilizing the ripple carry output stages
• Digital timing systems requiring asynchronous reset functionality

Counter Dividers Procurement Notes

Verify the specific package configuration, as the datasheet lists multiple physical options including SOIC, SOP, TSSOP, and PDIP. Confirm the ordering suffix matches the required tape and reel format if applicable. Ensure the manufacturer designation aligns with current corporate ownership structures following industry acquisitions. Cross-reference the pinout against the specific package number provided in the order documentation.

Counter Dividers Selection Notes

Select this component when a 12-stage binary counter is required with CMOS power efficiency and LS-TTL speed characteristics. Consider the 16-lead TSSOP package for space-constrained surface-mount designs. Evaluate the 2 V to 6 V operating range against system power constraints. Verify that the asynchronous reset logic meets the control requirements of the target application circuit.

Counter Dividers Part Context

This device belongs to the MM74HC40xx series of binary counters manufactured by Fairchild Semiconductor, now part of onsemi. It serves as a high-speed alternative to legacy CD4040 devices while maintaining pin compatibility. The series utilizes silicon-gate technology to bridge the performance gap between standard CMOS and Low-power Schottky TTL logic families.

Counter Dividers Replacement Considerations

The MM74HC4040 is pin equivalent to the CD4040. For direct replacements, verify the availability of the MM74HC4040MTC variant or other package styles listed in the ordering code table.
