TLV3404CDR

Comparators Overview

The TLV3404CDR is a quad nanopower open-drain output comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 16 V and draws a typical operating current of 640 nA. The device features rail-to-rail inputs, an input offset voltage of 3.6 mV, and an input bias current of 100 pA. It provides a response time of 30 µs, a common-mode rejection ratio of 88 dB, and a power supply rejection ratio of 105 dB. Each channel supports an output current of 10 mA. The component functions across a temperature range of -40°C to +125°C and is housed in a 14-pin SOIC package.

Comparators Feature Summary

• Quad configuration with open-drain outputs for flexible interfacing
• Rail-to-rail input capability for wide signal range compatibility
• Nanopower consumption suitable for battery-operated applications

Comparators Applications

• Battery-powered sensing systems
• Threshold detection circuits
• General-purpose analog comparison tasks

Comparators Procurement Notes

Verify the specific suffix 'CDR' corresponds to the SOIC-14 package and tape-and-reel packaging format. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before procurement. Ensure the ordering part number matches the required package style and reel quantity specifications exactly.

Comparators Selection Notes

Select this component when low quiescent current is critical alongside rail-to-rail input requirements. The open-drain output necessitates external pull-up resistors for proper logic level translation. Consider the 30 µs response time against application speed needs. Verify that the 10 mA sink capability meets load requirements without exceeding thermal limits in the SOIC-14 package.

Comparators Part Context

This part belongs to the TLV3404 series of quad comparators from Texas Instruments. It shares functional similarities with other nanopower comparators but is distinguished by its specific rail-to-rail input stage and open-drain output architecture. The 'C' indicates commercial temperature range support, while 'DR' denotes the reel packaging variant.

Comparators Replacement Considerations

Check for direct pin-compatible alternatives such as the TLV3404IPW (TSSOP package) if board space constraints differ. Verify electrical parameter equivalence, particularly input offset voltage and supply current, when substituting with other quad comparators from different manufacturers.
