SN74LV123ADBR

Overview

The SN74LV123ADBR 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 SOIC package, with a typical propagation delay of 13 ns and output drive currents of 12 mA. It supports retriggerable operation and functions across an industrial temperature range of -40°C to 125°C.

Feature Summary

• Dual independent monostable multivibrator circuits
• Schmitt-trigger inputs for signal conditioning
• Retriggerable functionality for pulse width adjustment
• Wide operating voltage range from 2 V to 5.5 V

Applications

• Pulse timing and shaping circuits
• Frequency division applications
• Debouncing switches or contacts
• Delay line generation

Procurement Notes

Verify the specific suffix 'ADR' against official datasheets to confirm the SOIC-16 package type and tape-and-reel packaging configuration. Ensure compatibility with the required operating temperature range and logic family standards before integration into final designs.

Selection Notes

Select this component when dual independent monostable timing is required with Schmitt-trigger input noise immunity. Consider the 16-SOIC package constraints and the 2 V to 5.5 V supply voltage requirements relative to system power rails.

Part Context

This part belongs to the SN74LV123A logic series, which offers low-voltage CMOS performance. It is functionally compatible with other members of the LV monostable family but differs in package style and manufacturing revision indicated by the suffix.

Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74LV123APWR (TSSOP) or SN74LV123APW if package changes are acceptable. Verify electrical parameters match requirements before substituting.
