TLV3402IP

Comparators Overview

The TLV3402IP is a dual nanopower open-drain output comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 16 V and draws a typical operating current of 550 nA per channel. The device features rail-to-rail input capability and provides an open-drain output capable of sourcing up to 10 mA. Key electrical specifications include a maximum input offset voltage of 3.6 mV, a maximum input bias current of 250 pA, and a common-mode rejection ratio of 50 dB. It is housed in an 8-pin PDIP package and supports an extended industrial temperature range from -40°C to +125°C.

Comparators Feature Summary

• Dual-channel configuration with nanopower consumption for battery-operated applications
• Rail-to-rail input stage allowing operation across the full supply voltage range
• Open-drain output structure supporting flexible logic interfacing and voltage level translation

Comparators Applications

• Battery-powered sensing systems requiring ultra-low quiescent current
• Threshold detection circuits in portable instrumentation
• Voltage monitoring and supervision tasks in low-power embedded designs

Comparators Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's official datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments representatives prior to procurement. Ensure the selected component matches the required temperature grade and pinout configuration for the intended PCB layout.

Comparators Selection Notes

Select this component when dual comparators with minimal power consumption are required. The rail-to-rail inputs simplify interface design with sensors operating near supply rails. The open-drain outputs allow easy integration with various logic families. Consider the 3.6 mV offset voltage for precision threshold applications. Verify that the 10 mA output drive capability meets the load requirements of the downstream circuitry.

Comparators Part Context

The TLV3402IP belongs to the TLV340x series of nanopower comparators from Texas Instruments. This family includes single (TLV3401), dual (TLV3402), and quad (TLV3404) variants. These devices are designed for general-purpose analog comparison tasks where low power consumption is critical. The series utilizes LinCMOS technology to achieve high performance at very low supply currents.

Comparators Replacement Considerations

Direct substitutes include other dual nanopower comparators from Texas Instruments such as the TLV3402IDR or TLV3402ID. Cross-vendor replacements should match the 2.5-16 V supply range, rail-to-rail inputs, and open-drain output characteristics. Verify pinout compatibility and electrical parameters before substitution.
