SN74LV123ADR

Overview

The SN74LV123ADR is a dual retriggerable monostable multivibrator from the Texas Instruments 74LV series. 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-SOIC package with a propagation delay of 13 ns. Output drive capability is specified at 12 mA for both high and low states. It supports an operating temperature range from -40°C to 125°C.

Feature Summary

• Dual retriggerable monostable multivibrator configuration
• Schmitt-trigger inputs for signal conditioning
• Wide supply voltage operation from 2 V to 5.5 V

Applications

• Pulse timing generation
• Frequency division
• Timing delay applications

Procurement Notes

Verify the specific suffix 'ADR' corresponds to the 16-SOIC tape and reel packaging format. Confirm RoHS3 compliance status as indicated in current manufacturer documentation. Ensure the ordering part number matches the required package width and lead form for PCB layout compatibility.

Selection Notes

Select this component when dual independent monostable functions are required in a low-voltage logic family. The 74LV series offers faster switching speeds compared to standard LS counterparts while maintaining CMOS power efficiency. Verify that the 12 mA output drive meets load requirements and that the 2 V minimum supply aligns with system power rails.

Part Context

This part belongs to the SN74LV123A logic guide family, which defines electrical characteristics for the LV (Low-Voltage CMOS) technology. The 'ADR' suffix specifically denotes the surface-mount SOIC package variant manufactured by Texas Instruments. It serves as a direct functional replacement for other dual monostable multivibrators within the same logic family constraints.

Replacement Considerations

The Nexperia 74LV123D,112 is documented as a similar alternative. Verify pinout compatibility and electrical parameter alignment before substitution.
