SN74LVC1G123DCUT

Overview

The SN74LVC1G123DCUT is a single retriggerable monostable multivibrator from the Texas Instruments LVC logic family. It operates within a supply voltage range of 1.65 V to 5.5 V and supports standard voltages including 1.8 V, 2.5 V, 3.3 V, and 5 V. The device features Schmitt-trigger inputs for noise immunity and delivers output currents of ±32 mA. Key electrical parameters include a maximum propagation delay of 18.6 ns at 1.65 V and a maximum quiescent current of 20 µA. It is housed in an 8-pin VSSOP package and functions reliably across an industrial temperature range of -40°C to +125°C.

Feature Summary

• Single retriggerable monostable multivibrator architecture
• Schmitt-trigger inputs for enhanced noise filtering
• Wide operating voltage range supporting multiple logic levels
• High drive capability with ±32 mA output current

Applications

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

Procurement Notes

Verify the specific suffix DCUT corresponds to the cut-tape packaging format when ordering. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the procurement channel provides valid traceability documentation. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing design integration.

Selection Notes

Select this component when a single-channel retriggerable timer is required in a compact surface-mount form factor. The LVC series offers compatibility with various logic families due to its wide voltage range. Consider the 18.6 ns propagation delay for high-speed timing applications. The VSSOP-8 package is suitable for space-constrained designs requiring robust Schmitt-trigger input performance.

Part Context

This part belongs to the SN74LVC1G123 series of single-function logic ICs manufactured by Texas Instruments. It is designed as a low-voltage CMOS solution for portable and battery-operated applications. The device integrates a single monostable multivibrator with Schmitt-trigger inputs into a small footprint, providing a cost-effective alternative to discrete timing solutions in modern digital electronics.

Replacement Considerations

Direct substitutes within the same family include SN74LVC1G123DCTR and SN74LVC1G123DCUR, which share identical electrical specifications but differ in packaging quantities and reel formats. Verify that any replacement maintains the VSSOP-8 package dimensions and pin configuration to ensure board compatibility.
