74LVC1G123GM,125

Overview

The 74LVC1G123GM,125 is a single retriggerable monostable multivibrator with Schmitt trigger inputs manufactured by Nexperia. 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 features high noise immunity, direct interface with TTL levels, and IOFF circuitry for partial power-down applications. It provides ±24 mA output drive at 3.0 V and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Single retriggerable monostable multivibrator with Schmitt trigger inputs on all pins.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow current.
• Inputs accept voltages up to 5.5 V, enabling direct translation between 3.3 V and 5 V devices.

Applications

• Pulse generation and timing circuits.
• Debouncing switches or contacts.
• Frequency division in digital systems.

Procurement Notes

Verify the ordering suffix 'GM' corresponds to the specific package variant required, as standard datasheets list DP, DC, GT, GN, and GS packages. Confirm that the manufacturer listed matches the source documentation provided. Ensure the component status is active before finalizing procurement plans.

Selection Notes

Select this component when a single-channel monostable multivibrator with Schmitt triggers is needed. It is suitable for mixed-voltage environments due to its wide input voltage tolerance. Consider the external resistor and capacitor requirements for pulse width programming when designing the application circuit.
