SN74LVC1G123DCTT

Overview

The SN74LVC1G123DCTT 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 a propagation delay of 18.6 ns and maximum output currents of ±32 mA. It functions across an extended temperature range from -40°C to +125°C with a maximum quiescent current of 20 µA. The component is housed in an SSOP-8 surface-mount package.

Feature Summary

• Retriggerable operation allows pulse width extension upon receiving subsequent trigger signals during the timing interval.
• Schmitt-trigger inputs provide noise immunity for clean signal transitions.
• Wide operating voltage range ensures compatibility with low-power and standard logic systems.

Applications

• Pulse width modulation
• Timing delays
• Frequency division

Procurement Notes

Verify the specific suffix DCTT corresponds to the SSOP-8 package and cut tape or reel packaging configuration as listed by authorized distributors. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the ordering part number matches the exact manufacturer designation to avoid variant discrepancies.

Selection Notes

Select this component when a single-channel monostable circuit is required with Schmitt-trigger input characteristics. The wide voltage range suits applications interfacing between different logic levels. Consider the SSOP-8 footprint constraints and thermal performance limits when designing the PCB layout for high-temperature environments.

Part Context

This device belongs to the SN74LVC1G123 series of single monostable multivibrators. It utilizes CMOS technology to achieve low power consumption while maintaining robust drive capabilities. The LVC series is designed for general-purpose digital applications requiring precise timing control in compact form factors.

Replacement Considerations

Check for direct pin-compatible alternatives within the same LVC family or other manufacturers offering identical monostable functionality in SSOP-8 packages. Verify that substitute parts maintain the same voltage range, output current ratings, and propagation delay specifications.
