SN74LV123ADGVR

Overview

The SN74LV123ADGVR is a dual monostable multivibrator integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device provides two independent circuits in a 16-pin TVSOP package with a maximum propagation delay of 13 ns. It supports output currents of 12 mA at both high and low states, ensuring robust driving capability across industrial temperature ranges from -40°C to 125°C.

Feature Summary

• Dual monostable multivibrator configuration with independent timing circuits
• Schmitt-trigger inputs provide enhanced noise rejection capabilities
• Wide operating voltage range supporting 2 V to 5.5 V power supplies
• Industrial temperature rating extending from -40°C to 125°C

Applications

• Pulse width generation and timing control
• Frequency division and pulse stretching
• Debouncing switches and contacts
• Timing delays in digital logic systems

Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSOP-16 package variant when sourcing. Confirm RoHS compliance status matches current manufacturing standards. Ensure compatibility with surface-mount assembly processes suitable for thin-shrink small-outline packages. Cross-reference datasheet revisions to validate pinout consistency.

Selection Notes

Select this component for designs requiring precise single-shot pulse generation with Schmitt-trigger input conditioning. The wide voltage range accommodates various logic families. Consider the TVSOP package constraints regarding thermal dissipation and board space. Verify that the 13 ns propagation delay meets system timing requirements.

Part Context

This part belongs to the SN74LV123A series of dual retriggerable monostable multivibrators. It shares functional characteristics with other LV-series logic devices but is distinguished by its specific TVSOP packaging and timing parameters. The series is designed for low-voltage applications requiring reliable pulse shaping and timing functions.

Replacement Considerations

Direct substitutes include SN74LV123APWR (TSSOP-16) and SN74LV123ADR (SOIC-16). These alternatives offer identical electrical performance but differ in physical package dimensions. Verify footprint compatibility before substitution.
