SN74LV123APWR

Overview

The SN74LV123APWR is a dual retriggerable monostable multivibrator from the Texas Instruments 74LV series, housed in a 16-TSSOP package. It operates on a supply voltage range of 2 V to 5.5 V and supports propagation delays as low as 13 ns. The device features Schmitt-trigger inputs for noise immunity and provides output currents of 12 mA at both high and low states. It functions within an industrial temperature range of -40°C to 125°C.

Feature Summary

• Dual independent monostable multivibrator circuits with retriggerable functionality
• Schmitt-trigger inputs provide enhanced noise filtering and signal conditioning
• Wide operating voltage range compatible with 2 V to 5.5 V power supplies
• High drive capability with 12 mA output current sourcing and sinking

Applications

• Pulse width generation and timing control circuits
• Debouncing switches and touch-sensitive interfaces
• Frequency division and pulse stretching applications
• Delay line implementations in digital logic systems

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the 16-TSSOP tape-and-reel packaging configuration. Confirm RoHS compliance status matches REACH requirements for the target market. Ensure the ordering part number aligns with the required moisture sensitivity level and lead-free manufacturing standards specified by Texas Instruments.

Selection Notes

Select this component when dual retriggerable monostable operation is required in a compact surface-mount form factor. The LV series offers lower power consumption compared to legacy counterparts while maintaining compatibility with standard logic levels. Consider the 16-TSSOP package dimensions for PCB layout constraints and thermal management requirements during system design.

Part Context

This device belongs to the SN74LV123A family of dual monostable multivibrators. It serves as a modern replacement for older TTL-based solutions, offering improved performance metrics and lower power dissipation. The component is widely used in embedded systems requiring precise timing intervals and reliable signal regeneration in noisy environments.

Replacement Considerations

SN74LV123ADRG4 is a verified equivalent variant with identical electrical characteristics but different packaging or manufacturing origin details.
