TLC339IPWR

Comparators Overview

The TLC339IPWR is a quad micropower comparator from Texas Instruments, utilizing LinCMOS technology. It features four independent channels in a 14-TSSOP package with surface-mount installation. 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 static current of 100µA. The output type is CMOS open-drain, supporting a typical output current of 20mA. It offers a typical CMRR of 84dB and a maximum propagation delay of 4.5µs. The input offset voltage is typically 5mV at 10V. The operating temperature range extends from 0°C to 70°C.

Comparators Feature Summary

• Integrates four independent comparators within a single low-power LinCMOS integrated circuit.
• Features ultra-low input bias current capability for high-impedance signal applications.
• Provides flexible single-supply operation across a wide voltage range.
• Utilizes open-drain outputs compatible with various logic families.

Comparators Applications

• Battery-powered portable devices requiring minimal quiescent current
• Threshold detection circuits for voltage monitoring
• Signal conditioning in industrial control systems

Comparators Procurement Notes

Verify the specific suffix IPWR corresponds to the 14-TSSOP package and tape-and-reel packaging configuration. Confirm that the commercial grade (C) rating meets the required 0°C to 70°C operating temperature range for the target application environment. Ensure compatibility with standard surface-mount assembly processes.

Comparators Selection Notes

Select this component when multiple comparator channels are needed in a compact surface-mount footprint. It is suitable for designs prioritizing low power consumption over high-speed performance. Consider the open-drain output requirement for pull-up resistor implementation. Verify that the 4.5µs propagation delay is sufficient for the intended signal frequencies.

Comparators Part Context

The TLC339 belongs to Texas Instruments' LinCMOS comparator family, designed for low-power applications. It serves as a quad-channel alternative to dual-channel variants like the TLC393. The IPWR designation indicates a plastic small-outline package variant optimized for automated surface-mount manufacturing.
