Overview
The SN74LV123ADB is a dual retriggerable monostable multivibrator from Texas Instruments, housed in a 16-pin SSOP package. It operates within a supply voltage range of 2 V to 5.5 V and features Schmitt-trigger inputs for enhanced noise immunity. The device supports propagation delays as low as 13 ns and provides output currents of 12 mA at both high and low states. It functions reliably across an extended temperature range of -40°C to 125°C.
Feature Summary
- Dual independent monostable multivibrators with retrigger capability
- Schmitt-trigger inputs provide improved noise immunity
- Low power consumption with maximum quiescent current of 20 µA
Applications
- Timing precision circuits
- Signal oscillation generation
- Programmable timer applications
Procurement Notes
Verify the specific package type, as the SN74LV123A family includes various suffixes such as ADR (SOIC) and ADB (SSOP). Confirm that the required pinout and physical dimensions match the design constraints. Ensure the component meets RoHS3 compliance standards if applicable to the manufacturing process. Cross-reference the datasheet revision to ensure compatibility with existing design documentation.
Selection Notes
Select this component when dual timing channels are required in a compact surface-mount form factor. The LV series logic level ensures compatibility with low-voltage digital systems. Consider the SSOP package availability against board space limitations. Verify that the 2V minimum supply voltage aligns with the system's power architecture before finalizing the bill of materials.
Part Context
This part belongs to the Texas Instruments 74LV series of logic devices, designed for low-voltage CMOS applications. The SN74LV123A variant specifically addresses the need for reliable pulse generation and timing control in consumer and industrial electronics. It serves as a standard solution for debouncing and delay generation tasks in modern digital circuit designs.
Replacement Considerations
Direct substitutes include other SN74LV123 variants with different packages, such as SN74LV123ADBR or SN74LV123APWR, provided the pinout remains compatible. Verify electrical characteristics and package dimensions before substitution.
