TLC393IDG4

Comparators Overview

The TLC393IDG4 is a dual micropower LinCMOS voltage comparator manufactured by Texas Instruments. It operates on a single supply voltage ranging from 3 V to 16 V. The device features an open-drain output type and provides two channels per package. Key electrical parameters include a maximum response time of 4.5 µs, a typical quiescent current of 40 µA, and a common-mode rejection ratio of 84 dB. It supports a maximum output current of 6 mA per channel with an input offset voltage of 5 mV. The component functions within a temperature range of -40°C to +125°C and is housed in an 8-pin SOIC surface-mount package.

Comparators Feature Summary

• Dual-channel architecture utilizing LinCMOS technology for low power consumption
• Open-drain output configuration compatible with various logic families
• Wide single-supply voltage operation capability

Comparators Applications

• General-purpose analog signal comparison
• Voltage monitoring circuits
• Threshold detection systems

Comparators Procurement Notes

Verify the specific suffix 'DG4' indicates the tape-and-reel packaging variant distinct from tube-packaged versions like 'ID'. Confirm RoHS compliance status through official manufacturer documentation as lead-free designations may vary by production batch. Ensure the ordering part number matches the required package style for PCB layout compatibility.

Comparators Selection Notes

Select this component when a low-power, dual-channel comparator is required for single-supply applications. The open-drain output allows flexible interfacing with different logic levels. Consider the 4.5 µs propagation delay for timing-sensitive designs. Verify that the 16 V maximum supply voltage meets system requirements.

Comparators Part Context

This device belongs to the TLC393 family of dual micropower comparators. It shares functional similarities with the LM393 but utilizes LinCMOS technology for significantly lower power consumption. The 'D' suffix denotes the SOIC-8 package, while 'G4' typically signifies lead-free construction and specific packaging configurations defined by Texas Instruments.
