SN74LV123ARGYRG4

Overview

The SN74LV123ARGYRG4 is a dual retriggerable monostable multivibrator from Texas Instruments' LV 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 a propagation delay of 13 ns and delivers output currents of ±12 mA. It is housed in a 16-VQFN (4x3.5) package, suitable for surface-mount applications across industrial temperature ranges.

Feature Summary

• Dual retriggerable monostable multivibrator configuration
• Schmitt-trigger inputs for enhanced noise filtering
• CMOS output structure with high drive capability

Applications

• Pulse width generation
• Timing delays
• Frequency division

Procurement Notes

Verify the specific suffix 'RG4' against the manufacturer's official datasheet to confirm RoHS compliance status and lead-free manufacturing details. Ensure the 16-VQFN (4x3.5) package dimensions match your PCB footprint requirements precisely before finalizing procurement orders.

Selection Notes

Select this component when dual independent timing channels are required in a compact surface-mount form factor. The LV series offers compatibility with 2V to 5.5V systems, making it suitable for low-voltage digital interfaces where Schmitt-trigger input hysteresis is necessary to prevent false triggering from noisy signals.

Part Context

This part belongs to the SN74LV123A logic family, which consists of dual retriggerable monostable multivibrators. The 'ARGYR' designation indicates the specific tape-and-reel packaging and VQFN-16 body style, while 'G4' typically denotes environmental compliance attributes defined by Texas Instruments.

Replacement Considerations

The SN74LV123ADRG4 is a documented substitute offering identical functionality in a 16-SOIC package. Verify pin-to-pin compatibility and thermal performance differences between the VQFN and SOIC packages during integration.
