74LVC1G123DP-Q10AH

Overview

The Nexperia 74LVC1G123DP-Q10AH is a single retriggerable monostable multivibrator from the 74LVC family, housed in an 8-TSSOP package. It operates on a supply voltage range of 1.65 V to 5.5 V with a maximum static current of 20 μA. The device provides output drive currents of ±32 mA and features Schmitt trigger inputs for high noise immunity. Key electrical parameters include a minimum pulse width of 2.5 ns and a propagation delay of 19 ns at CL. It supports partial power-down applications via IOFF circuitry and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Retriggerable monostable operation allows extension of output pulse width up to 100% duty factor through active edge inputs.
• Schmitt trigger inputs provide high noise immunity and tolerance for slow input rise and fall times.
• IOFF circuitry disables outputs during partial power-down to prevent damaging backflow currents.

Applications

• Timing generation and pulse width modulation
• Debouncing of mechanical switches
• Frequency division and pulse stretching

Procurement Notes

Verify the specific suffix 'Q10AH' against official Nexperia documentation to confirm automotive qualification status and exact pinout compatibility. Ensure the ordering part number matches the required tape-and-reel packaging specifications. Cross-reference the manufacturer's latest datasheet revision to validate RoHS compliance and REACH status before finalizing procurement orders.

Selection Notes

Select this component when a single-channel monostable multivibrator with Schmitt trigger inputs is required for low-power CMOS logic designs. The wide supply voltage range supports mixed 3.3 V and 5 V environments. Consider the 8-TSSOP package dimensions for space-constrained PCB layouts requiring surface-mount installation.

Part Context

This device belongs to the 74LVC1G123 series of single monostable multivibrators. It shares functional characteristics with other members of the 74LVC family but is distinguished by its specific automotive-grade suffix and TSSOP-8 packaging configuration designed for compact electronic assemblies.

Replacement Considerations

Check Nexperia's official replacement matrix for equivalent automotive-qualified monostable multivibrators. Verify that any substitute maintains identical Schmitt trigger functionality and compatible output drive capabilities.
