74LVC1G123GS,115

Overview

The Nexperia 74LVC1G123GS,115 is a single retriggerable monostable multivibrator featuring Schmitt trigger inputs. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device provides high noise immunity with direct interface capabilities for TTL levels. Output pulse width is programmable via external resistor (REXT) and capacitor (CEXT), allowing extension through retriggering on active HIGH or LOW edges. It includes IOFF circuitry for partial power-down applications.

Feature Summary

• Retriggerable monostable multivibrator with Schmitt trigger inputs
• Wide supply voltage range from 1.65 V to 5.5 V
• IOFF circuitry prevents damaging backflow current during power-down
• Direct reset terminates output pulse immediately

Applications

• Pulse generation and timing circuits
• Debouncing switches and contacts
• Frequency division
• Timing delays in mixed 3.3 V and 5 V environments

Procurement Notes

Verify the specific ordering suffix ',115' against official Nexperia documentation to confirm the XSON8 package type and reel specifications. Ensure compatibility with system voltage requirements between 1.65 V and 5.5 V. Confirm thermal management needs as total power dissipation derates linearly above 81 °C for this package variant. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a single-channel monostable multivibrator with Schmitt trigger inputs is required. It is suitable for designs needing retriggerable functionality to extend pulse widths up to a 100% duty factor. Consider the XSON8 package for space-constrained PCB layouts. Verify that input signals are compatible with the specified voltage thresholds across the operating temperature range.

Part Context

This part belongs to the 74LVC family of logic devices, designed for low-voltage CMOS applications. The 74LVC1G123 series offers a single monostable multivillator in various small packages. The GS suffix specifically denotes the XSON8 package configuration, providing a compact solution for modern electronic designs requiring minimal footprint.

Replacement Considerations

Consult official Nexperia substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully when replacing with other monostable multivibrators.
