SN74LV123APWT

Overview

The SN74LV123APWT is a dual retriggerable monostable multivibrator from Texas Instruments' 74LV series, housed in a 16-pin TSSOP package. It operates on a supply voltage of 2 V to 5.5 V with output currents of 12 mA high and low. Key electrical parameters include a propagation delay of 13 ns, a minimum pulse width of 5 ns, and a maximum delay of 36 ns at 2.5 V. The device features Schmitt-trigger inputs and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual retriggerable monostable multivibrator architecture
• Schmitt-trigger inputs for noise immunity
• Wide supply voltage operation from 2 V to 5.5 V

Applications

• Pulse timing circuits
• Frequency division
• Timing delays

Procurement Notes

Verify the specific suffix 'A' and 'W' to confirm the TSSOP-16 package and industrial temperature grade. Confirm RoHS3 compliance status as indicated in official documentation. Check for obsolescence notices, as some sources indicate this specific part number may be scheduled for discontinuation by the manufacturer.

Selection Notes

Select this component when dual independent monostable circuits are required in a compact surface-mount form factor. Ensure the design accommodates the 2 V to 5.5 V supply range and that the 12 mA drive capability meets load requirements. Verify thermal management for the TSSOP package if operating near the upper temperature limits.

Part Context

This part belongs to the SN74LV123 family of logic multivibrators. It shares functional similarities with variants like the SN74LV123ADR (SOIC) but differs in physical packaging. The 'A' suffix typically denotes an extended or industrial temperature range compared to standard commercial grades.

Replacement Considerations

SN74LV123APWR is a verified substitute offering identical functionality in a 16-TSSOP package.
