74LV123D-Q100J

Overview

The Nexperia 74LV123D-Q100J is a dual retriggerable monostable multivibrator with reset, operating within a supply voltage range of 1.0 V to 5.5 V. It features Schmitt-trigger action on inputs nA and nB for tolerance to slow rise and fall times. The device supports direct reset via input nRD and allows pulse width extension through retriggering. Propagation delay from inputs to output ranges from 14 ns to 92 ns depending on voltage and temperature. It complies with AEC-Q100 Grade 1 standards and operates between -40 °C and +125 °C.

Feature Summary

• Automotive qualified in accordance with AEC-Q100 (Grade 1) for high reliability applications
• Dual retriggerable architecture enables extended output pulses up to 100% duty factor
• Schmitt-trigger inputs provide noise immunity and tolerance for slow signal transitions
• Direct reset input terminates active output pulses immediately

Applications

• Timing generation and pulse shaping circuits
• Debouncing switches or mechanical contacts
• Frequency division and pulse stretching
• Delay line implementations

Procurement Notes

Verify the specific suffix 'J' against the manufacturer's current ordering information to confirm package type and tape/reel specifications. Ensure the design accounts for the SO-16 plastic small outline package dimensions and thermal derating requirements above 110 °C. Confirm compliance with RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when automotive qualification and wide voltage operation are required. It is suitable for mixed-voltage environments due to TTL-compatible input levels at specific supply voltages. Consider external timing components carefully as pulse width depends on REXT and CEXT values. Verify that the low power dissipation meets system thermal constraints.

Part Context

This part belongs to the 74LV123-Q100 family of logic ICs manufactured by Nexperia. It is designed for automotive electronics requiring robust performance under varying temperature conditions. The device integrates CMOS technology to minimize static power consumption while maintaining high-speed switching capabilities suitable for modern digital systems.

Replacement Considerations

The 74LV123D-Q100 is functionally compatible with other 74LV123 variants in the same series. Check pinout compatibility if substituting with different package options such as TSSOP16. Ensure replacement parts also meet AEC-Q100 Grade 1 requirements for automotive use.
