TLC339CPWR

Comparators Overview

The TLC339CPWR is a quad comparator from Texas Instruments' LinCMOS family, housed in a 14-TSSOP surface-mount package. It operates on a single supply voltage ranging from 3V to 16V. Key electrical specifications include a maximum input bias current of 5pA at 5V, a typical static current of 100µA, and an output current capability of 20mA. The device features a maximum propagation delay of 4.5µs and a common-mode rejection ratio (CMRR) of 84dB. Input offset voltage is limited to 5mV at 10V. It supports industrial operating temperatures from 0°C to 70°C.

Comparators Feature Summary

• LinCMOS technology enables low power consumption with micropower operation capabilities.
• Open-drain CMOS outputs allow flexible interfacing with various logic families.
• High input impedance minimizes loading effects on preceding circuit stages.

Comparators Applications

• General-purpose voltage monitoring
• Threshold detection circuits
• Level shifting applications

Comparators Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-14 package and tape-and-reel delivery format. Confirm RoHS compliance status matches current manufacturing standards. Ensure the industrial temperature range meets system requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Comparators Selection Notes

Select this component when a quad comparator with low input bias current is required. The open-drain output necessitates external pull-up resistors for proper logic level generation. Consider the 4.5µs propagation delay for timing-sensitive designs. Verify that the 14-TSSOP footprint aligns with the PCB layout constraints and thermal management strategy for the target application environment.

Comparators Part Context

This device belongs to the TLC339 series, which includes variants like the TLC339CN and TLC339DR. It shares functional similarities with the LM339 but utilizes LinCMOS technology for lower power dissipation. The CPWR designation specifically identifies the commercial temperature grade and plastic small-outline package type within the broader Texas Instruments comparator portfolio.

Comparators Replacement Considerations

TLC339DR serves as a direct pin-compatible alternative in SOIC-14 packaging. TLC339CN offers the same functionality in a PDIP-14 through-hole package. These substitutes maintain identical electrical characteristics and pinouts, facilitating easy board upgrades or prototyping transitions without redesigning the schematic.

Comparators FAQ

What is the output configuration of the TLC339CPWR?

The outputs are open-drain CMOS type, requiring external pull-up resistors to define the high logic state.

Does the TLC339CPWR support dual supply operation?

No, the datasheet specifies a single supply voltage range of 3V to 16V; it does not support dual supply configurations.
