74LVC1G123DC,125

Overview

The Nexperia 74LVC1G123DC,125 is a single retriggerable monostable multivibrator with Schmitt trigger inputs. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features ±24 mA output drive capability at 3.0 V and includes IOFF circuitry for partial power-down applications. Propagation delay ranges from 1.2 ns to 17.6 ns depending on load capacitance and voltage. It is housed in an 8-lead VSSOP package (SOT765-1) with a body width of 2.3 mm.

Feature Summary

• Retriggerable monostable multivibrator with Schmitt trigger inputs for noise immunity
• IOFF circuitry prevents damaging backflow current during partial power-down
• Direct interface with TTL levels and overvoltage tolerant inputs up to 5.5 V

Applications

• Pulse generation and timing control
• Debouncing switches or contacts
• Frequency division circuits

Procurement Notes

Verify the ordering suffix '125' corresponds to the standard tape-and-reel packaging format as defined by Nexperia. Confirm that the VSSOP8 (SOT765-1) package variant matches the specific footprint requirements of the target PCB design. Ensure compliance with RoHS3 and REACH regulations for the intended market.

Selection Notes

Select this component when a single-channel monostable function with high noise immunity is required. The VSSOP8 package offers a compact solution for space-constrained designs. Consider the external resistor and capacitor values needed to achieve the desired pulse width, noting that the device supports retriggering for extended pulse durations.

Part Context

This part belongs to the 74LVC1G123 family of single monostable multivibrators. It shares functional characteristics with other variants in the series but differs in package type. The DC suffix specifically denotes the VSSOP8 plastic very thin shrink small outline package, distinguishing it from TSSOP or XSON options.

Replacement Considerations

Other packages within the same logical family, such as 74LVC1G123DP (TSSOP8), offer identical electrical performance. Verify pinout compatibility and physical dimensions before substituting with alternative package types.
