74LVC1G123DCTRG4

Overview

The SN74LVC1G123DCTRG4 is a single retriggerable monostable multivibrator from Texas Instruments' LVC logic family. It operates within a supply voltage range of 1.65 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device provides a propagation delay of approximately 18.6 ns at 1.8 V and supports output currents of ±32 mA. It functions across an extended temperature range of -40°C to +125°C and is housed in an 8-VSSOP package.

Feature Summary

• Retriggerable operation allows pulse width extension upon subsequent trigger events during the timing interval
• Schmitt-trigger inputs provide robust noise filtering and clean signal transitions
• Wide operating voltage compatibility supports both low-power and standard logic systems

Applications

• Pulse width modulation and timing control circuits
• Debouncing mechanical switches and eliminating contact bounce
• Generating precise time delays in digital systems

Procurement Notes

Verify the suffix 'E4' indicates lead-free construction compliant with RoHS standards. Confirm the 'TR' designation corresponds to tape and reel packaging for automated assembly. Ensure the specific grade matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when a compact, single-channel monostable solution is required. It is suitable for designs needing Schmitt-trigger input hysteresis to handle slow or noisy signals. Consider the VSSOP-8 package for space-constrained PCB layouts requiring surface-mount technology.

Part Context

This part belongs to the SN74LVC1G123 series of single retriggerable monostable multivibrators. It is manufactured by Texas Instruments using CMOS technology. The device is designed for high-speed applications requiring low power consumption and wide voltage operation within the LVC logic family.

Replacement Considerations

Compatible substitutes include SN74LVC1G123DCTR and SN74LVC1G123DCUR. Verify pinout and electrical characteristics match before substitution.
