Overview
The Nexperia 74LV123PW,112 is a dual retriggerable monostable multivibrator with reset housed in a TSSOP16 (SOT403-1) 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. Propagation delays vary by voltage: typical values are 120 ns at 1.2 V, 40 ns at 2.0 V, 30 ns at 2.7 V, 25 ns at 3.0 V to 3.6 V, and 18 ns at 4.5 V to 5.5 V.
Feature Summary
- Dual retriggerable architecture allows extending output pulse width indefinitely via edge-triggered inputs.
- Schmitt-trigger action on nA and nB inputs provides tolerance for slow input rise and fall times.
- Direct reset input terminates output pulses immediately upon receiving a LOW-going edge.
- CMOS construction ensures low power dissipation across the entire operating voltage range.
Applications
- Pulse width generation
- Timing delay circuits
- Frequency division
Procurement Notes
Verify the specific ordering suffix '112' corresponds to the TSSOP16 package variant when sourcing. Confirm that the component status remains active as per the latest manufacturer documentation before finalizing procurement plans.
Selection Notes
Select this device for designs requiring precise timing control with external RC components. The wide supply voltage range accommodates both low-voltage and standard logic systems. Ensure input transition rates comply with specified limits to maintain signal integrity.
Part Context
This component belongs to the 74LV series of low-voltage CMOS logic devices. It functions as a monostable multivibrator, providing a single stable state that transitions temporarily upon triggering. The dual configuration offers two independent channels within a single integrated circuit.
Replacement Considerations
The 74LV123D is an alternative package version of the same logical function. Verify pin compatibility and thermal requirements when substituting between TSSOP and SO packages.
FAQ
How is the output pulse width determined?
The basic output pulse width is programmed by selecting external resistor (REXT) and capacitor (CEXT) components connected to the respective pins.
Can the output pulse be extended after triggering?
Yes, the device is retriggerable. Applying another trigger pulse while the output is active extends the pulse period.
