TLC393ID

Comparators Overview

The TLC393ID is a dual micropower LinCMOS voltage comparator manufactured by Texas Instruments. It operates on a single power supply ranging from 3V to 16V and features an open-drain output configuration. The device includes two independent comparators within an 8-pin SOIC package. Key electrical specifications include a maximum input bias current of 5pA at 5V, a typical common-mode rejection ratio (CMRR) of 84dB, and a maximum propagation delay of 4.5µs. It supports a wide operating temperature range from -40°C to +85°C.

Comparators Feature Summary

• LinCMOS technology enables low power consumption while maintaining high input impedance.
• Open-drain outputs allow flexible interfacing with various logic families through external pull-up resistors.
• Wide single-supply voltage operation provides compatibility across diverse system power rails.

Comparators Applications

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

Comparators Procurement Notes

Verify the specific suffix ID against the manufacturer's official documentation to confirm the SOIC package type and industrial temperature rating. Ensure that the open-drain output requirement aligns with the target circuit design, as this component lacks internal pull-up mechanisms. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market.

Comparators Selection Notes

Select this component when low static current and high input impedance are critical for battery-powered or energy-efficient designs. The dual-channel architecture reduces board space compared to using single comparators. Consider the propagation delay characteristics if timing precision is required in the application. Verify that the load connected to the open-drain output can handle the specified sink current capabilities.

Comparators Part Context

This part belongs to the TLC393 family of micropower comparators, which utilizes LinCMOS technology to achieve performance comparable to bipolar devices with significantly lower power dissipation. The family offers multiple package options including PDIP, SOIC, and TSSOP variants to accommodate different manufacturing and assembly needs.
