Rochester Electronics TLC393IDR Environmental and export classification status description

The TLC393IDR is a dual comparator integrated circuit from Texas Instruments. It consists of two independent, high-speed, precision voltage comparators built using CMOS technology. The TLC393 is designed for operation in a variety of applications, including low-power and battery-operated devices, signal processing, and precision instrumentation. Functions 1. Voltage Comparison: The primary function of the TLC393 is to compare two voltages and output a signal based on which voltage is higher. 2. Differential Input: Each comparator has two inputs, inverting (–) and non-inverting (+), allowing it to handle differential signal processing. 3. Open-Collector Outputs: The output stages are open-collector, providing flexibility for interfacing with different voltage levels and external pull-up resistors. 4. Low Supply Voltage Operation: It operates on a low supply voltage range (2V to 15V), making it suitable for battery-powered applications. 5. Low Power Consumption: The design focuses on efficient low-power performance, making it ideal for portable devices. Applications 1. Analog Signal Processing: Used in applications where analog signals need to be converted to digital signals. 2. Zero Crossing Detectors: Useful in detecting when a signal crosses zero volts, often used in AC signal processing. 3. Voltage Level Detection: Employed in circuits for determining when a particular voltage level is reached. 4. Temperature Sensors: Can be utilized in conjunction with temperature sensors for temperature monitoring and control. 5. Battery Management: Ideal for applications in battery-powered devices where monitoring battery voltage is essential. Alternative Parts 1. LM393: A standard dual comparator with similar functionality but you may need to check specifications for specific application requirements. 2. LMV393: A low-voltage comparator which can be an alternative with different voltage characteristics. 3. TLV393: Another dual comparator option optimized for low voltage and low power consumption. 4. TLH393: A high-speed option for applications requiring faster response times. Embedded Modules The TLC393 is often integrated into more complex systems or embedded modules, such as: 1. Microcontroller Development Boards: Used for voltage level detection or signal conditioning in embedded systems. 2. Sensor Modules: Integrated into sensor systems for analog signal processing. 3. Power Management Circuits: Used in designs focused on battery management systems to regulate power levels. Related Q&A 1. Q: What is the supply voltage range for the TLC393IDR comparator?
