SN74LV123APWRG4

Overview

The SN74LV123APWRG4 is a dual monostable multivibrator integrated circuit from Texas Instruments, housed in a 16-TSSOP surface-mount package. It operates within 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 symmetric output drive currents of 12 mA at both high and low states. Designed for industrial environments, it functions reliably across an extended 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
• Symmetric output drive capability ensures consistent signal integrity
• Extended industrial operating temperature range for robust performance

Applications

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

Procurement Notes

Verify the G4 suffix indicates RoHS compliance and green material status per manufacturer specifications. Confirm the TSSOP-16 package dimensions match your PCB footprint requirements. Ensure the supply voltage aligns with the 2 V to 5.5 V operational range. Check for any specific handling instructions related to moisture sensitivity level 1.

Selection Notes

Select this component when dual monostable timing is required in a compact surface-mount form factor. The LV series offers lower power consumption compared to older logic families while maintaining compatibility with standard interfaces. Consider the 13 ns propagation delay for high-speed timing applications. Verify that the 12 mA output current meets the load requirements of the connected circuitry.

Part Context

This part belongs to the SN74LV123A family of dual monostable multivibrators. The 'G4' suffix denotes lead-free packaging and RoHS compliance. It shares functional similarities with other LV-series timers but is distinguished by its specific package type and environmental certifications. It serves as a direct replacement for non-RoHS variants like the SN74LV123APWR in compliant designs.

Replacement Considerations

SN74LV123APWR is the non-RoHS equivalent with identical electrical characteristics. Nexperia 74LV123D is a pin-compatible alternative from another manufacturer. Onsemi 74VHC123AMX offers similar functionality but may require voltage level verification.
