74HC123PW-Q100,118

Overview

The Nexperia 74HC123PW-Q100,118 is a dual retriggerable monostable multivibrator with reset, housed in a TSSOP16 (SOT403-1) package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features CMOS low power dissipation and high noise immunity. Propagation delay ranges from 19 ns to 55 ns at 6.0 V. It includes Schmitt-trigger action on inputs nA and nB for tolerance to slow rise/fall times, direct reset functionality via input nRD, and ESD protection exceeding 2000 V (HBM).

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards.
• Dual retriggerable architecture allowing pulse extension up to 100% duty factor.
• Schmitt-trigger inputs provide high tolerance to slow signal transitions.
• Direct reset capability terminates output pulses immediately upon LOW-going edge.

Applications

• Timing generation and pulse width modulation circuits.
• Debouncing switches or contacts in automotive systems.
• Frequency division and timing delays in digital logic designs.

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the AEC-Q100 Grade 1 qualification requirements for your target application environment. Ensure compatibility with the specified operating temperature range and supply voltage constraints during system design validation.

Selection Notes

Select this component when dual independent monostable functions are required in a compact surface-mount form factor. The HC series offers a wide supply voltage range suitable for various logic families. Consider the TSSOP16 package dimensions for PCB layout constraints and thermal management requirements relative to other available package options.

Part Context

This part belongs to the Nexperia 74HC(HCT)123-Q100 family of dual retriggerable monostable multivibrators. It shares functional characteristics with variants such as the 74HC123D-Q100 and 74HCT123PW-Q100, differing primarily in package type and input logic level specifications. The Q100 suffix indicates automotive-grade qualification.

Replacement Considerations

The 74HC123D-Q100 serves as a pin-compatible alternative using the SO16 package. Verify that the replacement package fits the physical footprint and thermal dissipation requirements of the existing design before substitution.
