TLC339IDR

Comparators Overview

The TLC339IDR is a quad comparator from Texas Instruments' LinCMOS family, housed in a 14-SOIC package. It operates on a single supply voltage ranging from 3V to 16V. Key electrical parameters include a maximum input bias current of 5pA at 5V, a typical static current of 125µA, and a maximum propagation delay of 4.5µs. The device features an open-drain output capable of sourcing up to 20mA. It maintains a typical CMRR of 84dB and has a maximum input offset voltage of 5mV at 10V. The component supports surface mount installation and functions within a temperature range of -40°C to 85°C.

Comparators Feature Summary

• LinCMOS technology enables low power consumption with high noise immunity.

Comparators Applications

• General purpose analog signal comparison
• Voltage monitoring circuits
• Threshold detection systems

Comparators Procurement Notes

Verify the specific suffix 'IDR' corresponds to the standard SOIC-14 tape and reel packaging configuration. Confirm RoHS3 compliance status for environmental regulations. Ensure the operating temperature grade matches industrial requirements (-40°C to 85°C). Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and revision history before procurement.

Comparators Selection Notes

Select this component when a quad comparator with ultra-low input bias current is required. The wide single-supply voltage range allows flexibility in power design. Consider the open-drain output capability for interfacing with various logic families. Evaluate the propagation delay specifications against system timing constraints to ensure adequate response speed for the intended application.

Comparators Part Context

This part belongs to the TLC339 series, which utilizes LinCMOS technology to combine CMOS noise immunity with low power consumption. The series includes variants with different package options such as TSSOP and PDIP. The TLC339IDR specifically denotes the industrial temperature grade version in a surface-mount SOIC package, distinguishing it from commercial or military grade alternatives within the same functional family.

Comparators Replacement Considerations

Direct pin-compatible substitutes include the LM339DR and LM339DR2G. Verify that alternative parts meet the specific input bias current and voltage supply requirements of the original design.
