SN74LV123ARGYR

Overview

The SN74LV123ARGYR 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 is housed in a 14-pin HVQCCN (VQFN) package with dimensions of 3.5 mm length. It supports an operating temperature range from -40°C to 125°C, ensuring reliability in demanding environments.

Feature Summary

• Dual retriggerable monostable multivibrator architecture
• Schmitt-trigger inputs for signal conditioning
• Wide operating voltage range supporting 2 V to 5.5 V
• Extended industrial temperature capability up to 125°C

Applications

• Pulse width modulation circuits
• Timing delay generation
• Debouncing switches
• Frequency division

Procurement Notes

Verify the specific suffix ARGYR corresponds to the 14-VQFN package and tape-and-reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact package code and reel quantity specified in the manufacturer's current documentation.

Selection Notes

Select this component when dual independent timing channels are required in a compact surface-mount footprint. The LV logic family offers low power consumption suitable for battery-operated devices. Verify that the input voltage levels are compatible with the system logic family and that the external timing components can achieve the desired pulse width specifications.

Part Context

This device belongs to the SN74LV123 family of dual monostable multivibrators. It is functionally similar to other variants like the SN74LV123ADR or SN74LV123APWR but differs in package type. The VQFN package provides a small form factor advantage for space-constrained designs compared to SOIC or TSSOP alternatives.

Replacement Considerations

Check for pin-compatible alternatives such as SN74LV123ADR or SN74LV123APWR if package changes are acceptable. Verify electrical parameters match exactly before substitution.
