SN74LV123APW

Overview

The SN74LV123APW is a dual retriggerable monostable multivibrator from the Texas Instruments 74LV logic family. 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-TSSOP surface-mount package. Key electrical specifications include a propagation delay of 13 ns, output currents of ±12 mA, and an operating temperature range of -40°C to +85°C or +125°C depending on specific grade.

Feature Summary

• Dual retriggerable monostable multivibrator architecture
• Schmitt-trigger inputs for signal conditioning
• Wide supply voltage operation capability

Applications

• Pulse width generation
• Timing delay circuits
• Frequency division

Procurement Notes

Verify the exact suffix against the manufacturer's current datasheet to confirm package type and temperature rating. Ensure compatibility with system voltage levels and thermal requirements before integration. Cross-reference part numbers with official distributors to avoid counterfeit components.

Selection Notes

Select this component when dual independent timing channels are required in a compact surface-mount form factor. Consider the 74LV series characteristics for low-voltage applications requiring Schmitt-trigger input hysteresis. Evaluate power consumption and speed requirements against the specified propagation delay and supply current limits.

Part Context

This component belongs to the Texas Instruments 74LV (Low-Voltage CMOS) logic family. It is functionally compatible with other monostable multivibrators in the 74LV123 series, such as those in SOIC packages. The APW suffix specifically denotes the TSSOP-16 package variant.
