74LV393D-Q100J

Counter Dividers Overview

The Nexperia 74LV393D-Q100J is a dual 4-bit binary ripple counter qualified to AEC-Q100 Grade 1 standards for automotive applications. It operates within a supply voltage range of 1.0 V to 3.6 V and accepts TTL input levels between 2.7 V and 3.6 V. The device features two independent counters, each with an asynchronous master reset and four buffered parallel outputs. It advances on the HIGH-to-LOW clock transition and includes input clamp diodes for overvoltage tolerance. The component is housed in an SOIC-14 (SOT108) package.

Counter Dividers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Dual independent 4-bit binary ripple counters with individual clocks
• Asynchronous master reset inputs for immediate clearing of counter stages
• Input clamp diodes enabling interface to voltages exceeding VCC

Counter Dividers Applications

• Automotive electronic systems requiring binary counting
• Frequency division circuits utilizing binary modules up to 2^8
• Digital timing and sequencing logic in mixed-voltage environments

Counter Dividers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the D variant denotes SOIC-14 while PW denotes TSSOP-14. Confirm that the AEC-Q100 Grade 1 qualification aligns with the target automotive application's reliability requirements. Ensure design parameters remain within the specified temperature ranges and voltage limits defined in the official datasheet.

Counter Dividers Selection Notes

Select this component when dual independent 4-bit counters are required in a single package. It is suitable for designs needing low voltage operation down to 1.0 V or those requiring TTL level compatibility at higher voltages. Consider the SOIC-14 package constraints regarding thermal dissipation and board space compared to alternative packages like TSSOP.

Counter Dividers Part Context

This part belongs to the Nexperia 74LV series of low-voltage CMOS logic devices. The LV393 specifically provides dual 4-bit ripple counting functionality. The Q100 suffix indicates automotive qualification, distinguishing it from standard commercial grade counterparts. It is part of a broader family of logic ICs designed for robust performance in demanding environments.

Counter Dividers Replacement Considerations

The 74LV393PW-Q100J serves as a pin-compatible alternative offering the same logical function but packaged in TSSOP-14 instead of SOIC-14. Verify mechanical footprint compatibility before substitution.
