TLC352CDRG4

Comparators Overview

The TLC352CDRG4 is a dual differential voltage comparator fabricated using CMOS technology, housed in an 8-pin SOIC package. It operates from a single supply voltage ranging from 2.7V to 16V or dual supplies with a total difference within the same range. The device features extremely high input impedance and low bias current, making it suitable for high-impedance source interfacing. It includes built-in ESD protection rated at 2000V and offers open-drain outputs compatible with various logic families. The component is characterized for operation across the industrial temperature range of -40°C to 85°C.

Comparators Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging when ordering. Confirm the industrial grade variant is required for temperatures below 0°C. Ensure pull-up resistors are selected appropriately for the open-drain output configuration to manage rise times and power dissipation effectively.

Comparators Selection Notes

Select this component for applications requiring low power consumption and high input impedance. The open-drain output allows connection to external pull-up voltages independent of the supply rail. Consider the response time specifications when designing for high-speed signal processing requirements.

Comparators Part Context

This device belongs to the TLC352 family of micro-power comparators. It serves as a pin-compatible alternative to legacy components like the LM393 while offering improved CMOS performance characteristics. The series is designed for general-purpose analog comparison tasks in consumer and industrial electronics.

Comparators FAQ

How should unused inputs be handled on the TLC352?

Unused inputs must not be tied together. They should be connected to a voltage within the specified input range that provides a minimum of 50mV differential voltage to prevent high-frequency chatter caused by internal noise.

What is the maximum voltage allowed on the output relative to the supply rails?

The inputs or output must not exceed the supply rails by more than 300mV. Directly shorting the output to the pull-up voltage can cause thermal runaway if the voltage is high.
