Overview
The NXP USA Inc. 74LV123N,112 is a dual retriggerable monostable multivibrator housed in a DIP16 plastic dual in-line package (SOT38-4). It operates within a supply voltage range of 1.0 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features Schmitt-trigger action on inputs nA and nB for tolerance to slow signal transitions. Pulse width is programmed via external resistor and capacitor connections.
Feature Summary
- Dual retriggerable monostable multivibrator architecture
- Schmitt-trigger action on active HIGH and LOW edge inputs
- Direct reset input terminates output pulses immediately
- Compatible with 74HC123 and 74HCT123 pinouts
Applications
- Pulse generation circuits
- Timing delay applications
- Debouncing switches or contacts
Procurement Notes
Verify the specific ordering suffix '112' against current manufacturer documentation to confirm package type and environmental compliance status. Confirm that the DIP16 package designation aligns with your board layout requirements. Check for any recent product change notices regarding lead content or material composition updates.
Selection Notes
Select this component when a low-voltage CMOS monostable multivibrator with Schmitt-trigger inputs is required. Ensure the application utilizes external timing components compatible with the specified resistance and capacitance ranges. Verify that the operating voltage falls within the guaranteed functional limits of the device.
Part Context
This part belongs to the 74LV series of low-voltage logic devices manufactured by NXP Semiconductors. It provides functionally equivalent performance to standard 5V logic families while supporting lower supply voltages. The DIP16 package offers through-hole mounting capabilities suitable for prototyping or legacy system integration.
Replacement Considerations
The datasheet indicates pin and function compatibility with the 74HC123 and 74HCT123. These parts may serve as direct replacements if voltage levels and package types are verified.
