74HCT4040DB,112

Counter Dividers Overview

The Nexperia 74HCT4040DB,112 is a 12-stage binary ripple counter housed in a 16-lead TSSOP package (SOT403-1). It features an asynchronous master reset input and twelve parallel outputs. The device operates on the HIGH-to-LOW transition of the clock signal. Recommended supply voltage ranges from 4.5 V to 5.5 V with an operating temperature range of -40 °C to +125 °C. Maximum frequency is 79 MHz at 5.0 V.

Counter Dividers Feature Summary

• Complies with TTL input level standards for high noise immunity
• Includes clamp diodes on inputs to allow interfacing with voltages exceeding VCC using current limiting resistors
• ESD protection exceeds 2000 V per HBM and 1000 V per CDM

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Selection Notes

Select this component when a 12-bit binary counting solution compatible with standard TTL logic levels is required. Ensure the design accommodates the ripple counter architecture where output transitions propagate sequentially rather than simultaneously. Verify that the maximum operating frequency aligns with the system clock requirements under the intended load capacitance conditions.

Counter Dividers Part Context

This part belongs to the 74HCT series of CMOS logic devices manufactured by Nexperia. It serves as a digital counter within the broader family of 74xx logic components, providing a standardized interface for sequential logic applications in embedded systems and industrial control equipment.

Counter Dividers Replacement Considerations

Check for 74HC4040 variants if CMOS input levels are acceptable instead of TTL. Consider 74HCT4040PW or 74HCT4040BQ for alternative package types such as TSSOP or DHVQFN while maintaining functional equivalence.
