74LV123DB,112

Overview

The Nexperia 74LV123DB,112 is a dual retriggerable monostable multivibrator with reset housed in an SO16 plastic small outline package (SOT109-1). It operates on a supply voltage range of 1.0 V to 5.5 V and supports temperatures from -40 °C to +125 °C. The device features Schmitt-trigger action on inputs nA and nB for noise tolerance. Propagation delay ranges from 14 ns to 46 ns depending on voltage. Output current capability reaches ±12 mA at 4.5 V.

Feature Summary

• Dual retriggerable monostable multivibrator architecture
• Schmitt-trigger action on edge-triggered inputs
• Direct reset functionality terminates output pulses
• Wide supply voltage compatibility

Applications

• Timing pulse generation
• Debouncing switches
• Frequency division
• Pulse width modulation

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the SO16 package variant SOT109-1. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure external component selection for REXT and CEXT adheres to the recommended resistance and capacitance values provided in the datasheet.

Selection Notes

Select this component when dual independent timing channels are required within a single package. The LV series offers low power consumption suitable for battery-operated applications. Verify that the input voltage levels match the system logic requirements across the entire operating voltage range.

Part Context

This part belongs to the 74LV family of low-voltage CMOS logic devices. It provides two identical monostable circuits capable of generating precise time delays or fixed-width pulses. The design allows for direct interfacing with various logic families due to its wide voltage operation.
