74LVC1G123GD,125

Overview

The Nexperia 74LVC1G123GD,125 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 output drive current of ±24 mA at 3.0 V. The device provides high noise immunity and low power consumption. It includes IOFF circuitry for partial power-down applications. The component is specified for ambient temperatures from -40 °C to +125 °C and complies with JEDEC standards.

Feature Summary

• Retriggerable operation allows extension of the output pulse width up to a 100% duty factor via gated active LOW-going edge input (A) or active HIGH-going edge input (B).
• Schmitt trigger inputs on all pins provide high tolerance to slower input rise and fall times.
• IOFF circuitry disables the output during power-down to prevent damaging backflow currents.
• Direct reset input (CLR) terminates the output pulse immediately and inhibits further triggering.

Applications

• Timing generation in mixed 3.3 V and 5 V environments
• Pulse width modulation and timing control
• Debouncing switches and generating clean pulses

Procurement Notes

Verify the specific ordering suffix GD,125 against the manufacturer's latest documentation to confirm the package type and temperature range. Ensure compatibility with system voltage levels and load requirements before finalizing procurement specifications.

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 and direct reset capabilities within the 74LVC logic family constraints.

Part Context

This part belongs to the 74LVC1G123 series of single retriggerable monostable multivibrators. It is designed for low-voltage CMOS applications and offers multiple package options including TSSOP8, VSSOP8, and various XSON8 configurations.

Replacement Considerations

Check for alternative packages such as DC, GT, GN, or GS if different form factors are needed. Verify that any substitute maintains the same logic family characteristics and electrical specifications.
