SN74LV123ADRG4

Overview

The SN74LV123ADRG4 is a dual retriggerable monostable multivibrator from Texas Instruments' 74LV logic family. 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 output drive capabilities of 12 mA high and low. It supports propagation delays as low as 13 ns and functions across an industrial temperature range of -40°C to 125°C.

Feature Summary

• Dual retriggerable monostable multivibrator configuration
• Schmitt-trigger inputs for enhanced noise filtering
• Wide operating voltage range supporting 2 V to 5.5 V
• High-speed operation with low propagation delay

Applications

• Pulse timing and shaping circuits
• Frequency division applications
• Delay line generation
• One-shot pulse generation

Procurement Notes

Verify the specific suffix 'RG4' indicates lead-free packaging compliant with RoHS standards. Confirm the 16-SOIC package dimensions match the design footprint. Ensure the operating temperature range meets system requirements. Check for any specific handling instructions related to moisture sensitivity level 1.

Selection Notes

Select this component when dual independent monostable circuits are required in a compact surface-mount package. The LV series offers lower power consumption compared to older logic families while maintaining compatibility with standard digital interfaces. Verify that the input voltage levels align with the driving source logic family.

Part Context

This part belongs to the SN74LV123A logic guide series, representing the advanced low-voltage CMOS technology. It serves as a direct replacement for legacy 74LS123 devices in modern low-power designs. The 'ADR' designation specifies the SOIC-16 package and tape-and-reel shipping method.

Replacement Considerations

The SN74LV123ADRE4 is a verified equivalent part number offering identical electrical characteristics and pinout compatibility.
