TLC339CDB

Comparators Overview

The TLC339CDB is a quad comparator from Texas Instruments, part of the LinCMOS family. It features four independent comparators in a 14-SOIC package. The device operates on a single supply voltage ranging from 3V to 16V. Key electrical specifications include a maximum input bias current of 5pA at 5V and a typical output current of 20mA. The input offset voltage is typically 5mV at 10V. The propagation delay is specified at a maximum of 4.5µs. Common-mode rejection ratio (CMRR) is typically 84dB. The operating temperature range extends from -40°C to 85°C.

Comparators Procurement Notes

Verify the specific suffix 'CDB' against the manufacturer's official datasheet to confirm the package type and temperature grade. Ensure compatibility with the required operating environment and pinout configuration before integration into the design.

Comparators Selection Notes

Select this component when multiple independent comparison functions are required in a limited board area. Consider the open-drain output requirement for pull-up resistor implementation. Evaluate the 4.5µs propagation delay against system timing requirements.

Comparators Part Context

This component belongs to the TLC339 series of quad comparators. It shares functional similarities with other members like the TLC339IDR but differs in packaging and temperature rating. The 'C' suffix typically denotes commercial temperature range operation.

Comparators Replacement Considerations

Check for direct replacements such as the TLC339IDR or TLC339CPWR, ensuring package and temperature specifications match the original design requirements.
