74LV123D,118

Overview

The Nexperia 74LV123D,118 is a dual retriggerable monostable multivibrator with reset housed in an SO16 (SOT109-1) package. It operates within 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 inputs for noise immunity and accepts TTL levels between 2.7 V and 3.6 V. Propagation delays range from 14 ns to 120 ns depending on voltage. Output currents reach ±12 mA, and it complies with JEDEC standards for various voltage ranges.

Feature Summary

• Dual retriggerable monostable multivibrator architecture
• Schmitt-trigger action on trigger inputs for slow signal tolerance
• Direct reset capability to terminate output pulses immediately
• Wide supply voltage compatibility from 1.0 V to 5.5 V

Applications

• Pulse width generation and timing circuits
• Debouncing switches or contacts
• Frequency division and pulse stretching

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the SO16 plastic small outline package (SOT109-1). Confirm the temperature grade matches the required operational range of -40 °C to +125 °C. Ensure external component selection for REXT and CEXT adheres to the recommended operating conditions specified in the datasheet to maintain performance integrity.

Selection Notes

Select this component when dual independent monostable channels are required in a single package. The LV series offers low power dissipation suitable for battery-operated systems. Verify that the input voltage levels of the driving circuitry are compatible with the Schmitt-trigger thresholds, especially at lower supply voltages below 2.7 V.

Part Context

This part belongs to the Nexperia 74LV logic family, designed for low-voltage applications. The 'D' suffix indicates the SO16 package variant, while '118' denotes the standard tape and reel packaging configuration. It serves as a general-purpose timing element within digital logic systems requiring precise pulse control.

Replacement Considerations

Check for direct pin-compatible alternatives such as the 74LV123PW (TSSOP16) if package footprint changes are acceptable. Cross-reference with other manufacturers' 74LV123 equivalents ensuring identical logic functionality and electrical characteristics.
