Texas Instruments TLV3402ID

Overview

TLV3402ID from Texas Instruments is a dual-channel nanopower open-drain comparator with 470 nA per channel supply current, rail-to-rail input range (–0.1 V to VCC + 5 V), and operation across 2.5 V to 16 V supply. It features reverse battery protection up to 18 V and is rated for industrial temperature range (–40°C to +125°C), making it ideal for ultra-low-power battery-operated sensor monitoring circuits.

For engineers reviewing the TLV3402ID datasheet, TLV3402ID pinout, TLV3402ID application, or TLV3402ID equivalent, key selection criteria include quiescent current budget, input common-mode voltage margin beyond rails, open-drain output compatibility with mixed-voltage logic, and thermal performance in compact VSSOP-8 packaging.

Technical Context

The TLV3402ID uses a CMOS input stage enabling –0.1 V to VCC + 5 V input common-mode range and 80 pA typical input bias current. Its open-drain output requires external pull-up and supports level-shifting between domains - e.g., 5 V supply with 3.3 V logic interface.

It operates down to 2.5 V single supply (2.7 V minimum over full industrial range) and maintains 470 nA per channel supply current across –40°C to +125°C, with propagation delays of 55 µs (low-to-high) and 30 µs (high-to-low) at 50 mV overdrive and 5 V supply.

Key Specifications

Pinout & Package

TLV3402ID is housed in an 8-pin VSSOP package (3.00 mm × 3.00 mm), optimized for space-constrained portable designs. Thermal resistance R_θJA is 186.8°C/W, supporting operation up to +125°C ambient with minimal derating.

FAQ

What is the maximum input voltage allowed on TLV3402ID inputs?

The TLV3402ID supports an input common-mode voltage range of –0.1 V to VCC + 5 V, with absolute maximum input voltage limited to VCC + 5 V or 20 V - whichever is smaller. This allows safe high-side sensing above the supply rail, such as monitoring a 12 V bus with a 5 V VCC supply, provided the input does not exceed 10 V (5 V + 5 V).

Does TLV3402ID require external pull-up resistors on its outputs?

Yes, TLV3402ID has open-drain CMOS outputs and requires external pull-up resistors on both 1OUT and 2OUT pins to establish a defined high state. The datasheet specifies performance with a 1 MΩ pull-up; values between 10 kΩ and 10 MΩ are usable depending on speed vs. power trade-offs - lower resistance improves rise time but increases static current when output is low.

Can TLV3402ID operate from a 2.5 V supply across the full industrial temperature range?

TLV3402ID is specified for 2.5 V to 16 V operation, but the minimum supply for full –40°C to +125°C functionality is 2.7 V. At 2.5 V, operation is guaranteed only for the commercial range (0°C to +70°C). For industrial-grade reliability, maintain VCC ≥ 2.7 V across the entire temperature span.

What is the input offset voltage specification for TLV3402ID?

The TLV3402ID has a typical input offset voltage of 250 µV at 25°C, with a maximum of 3600 µV over the full industrial temperature range (–40°C to +125°C). This low offset enables accurate threshold detection in precision applications such as battery voltage monitoring or sensor zero-point calibration.

Is TLV3402ID pin-compatible with other dual comparators in VSSOP-8 packages?

TLV3402ID follows the standard VSSOP-8 pinout for dual comparators (GND, 1IN–, 1IN+, VCC, 2IN+, 2IN–, 2OUT, 1OUT), matching industry conventions used by TLV3702, TLC3702, and LMV393 variants. However, electrical differences - especially supply current, input range, and propagation delay - require validation before drop-in replacement.
