Overview
The SN74LV123ADRE4 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 provides two independent circuits in a 16-SOIC package, with propagation delays as low as 13 ns and output drive currents of 12 mA. It supports operation across an extended temperature range of -40°C to 125°C.
Feature Summary
- Dual retriggerable monostable multivibrator configuration
- Schmitt-trigger inputs for improved noise rejection
- Wide operating voltage range from 2 V to 5.5 V
- Extended industrial temperature capability
Applications
- Pulse timing and shaping circuits
- Frequency division applications
- Delay line generation
- Watchdog timer implementations
Procurement Notes
Verify the 'E4' suffix indicates lead-free composition compliant with RoHS standards. Confirm the SOIC-16 package dimensions match design constraints. Ensure the manufacturer source aligns with project quality requirements. Cross-reference the base part number SN74LV123A for identical electrical specifications.
Selection Notes
Select this component when dual independent monostable functions are required in a standard logic family. The LV series offers lower power consumption compared to older HCT variants. Verify that the 12 mA output current meets load requirements. Consider the 16-SOIC footprint for PCB layout compatibility.
Part Context
This part belongs to the Texas Instruments 74LV (Low-Voltage CMOS) logic family. It serves as a direct functional equivalent to the SN74LV123A, with the E4 suffix denoting specific manufacturing or packaging revisions. It is designed for general-purpose digital applications requiring reliable pulse generation.
Replacement Considerations
The SN74LV123ADR is a compatible alternative with identical electrical characteristics. Other manufacturers offer pin-compatible devices such as the Nexperia 74LV123D. Verify package tolerance and voltage levels before substitution.
