Texas Instruments TLV2352IPW

Overview

TLV2352IPW from Texas Instruments is a dual low-voltage differential comparator IC designed for single-supply operation down to 2V, featuring 120µA typical supply current at 3V, 5pA typical input bias current, and open-drain N-channel outputs requiring external pullup resistors - used in battery-powered voltage monitoring and precision threshold detection circuits.

For engineers reviewing the TLV2352IPW datasheet, TLV2352IPW pinout, TLV2352IPW application, or TLV2352IPW equivalent, key selection criteria include its 2V–8V supply range, 200ns TTL-level response time (for TLV2352IDR/IPWR variants), –40°C to 85°C operating temperature, TSSOP-8 package, and compatibility with TTL/MOS/CMOS logic interfaces.

Technical Context

The TLV2352IPW implements two independent CMOS-based comparators with rail-to-rail common-mode input range including ground, enabling direct sensing of signals referenced to system ground. Its high input impedance (>10¹²Ω) minimizes loading on high-impedance sources such as sensor bridges or photodiode amplifiers.

Each comparator features an open-drain N-channel output stage, supporting wired-AND configurations and flexible level translation via external pullup resistors. The device is fully characterized at 3V and 5V across –40°C to 85°C, with internal ESD protection rated at 1000V HBM.

FAQ

What is the operating temperature range for TLV2352IPW?

The TLV2352IPW is specified for operation from –40°C to +85°C. This industrial-grade temperature range is confirmed in the device comparison table and recommended operating conditions section of the official datasheet. All electrical characteristics for TLV2352IPW are fully characterized across this full range at both 3V and 5V supply voltages. The TLV2352IPW variant corresponds to the TLV2352I grade, distinct from the extended-range TLV2352M (–55°C to 125°C).

Does TLV2352IPW support rail-to-rail input common-mode voltage?

Yes, TLV2352IPW supports a common-mode input voltage range that includes ground (0V) and extends up to VDD–1.25V at 3V supply, per the VICR specification in Section 5.3 of the datasheet. This rail-to-ground input capability allows direct interface with sensors and signals referenced to system ground without level-shifting circuitry - a key enabler for single-supply applications.

What output configuration does TLV2352IPW use, and how should it be interfaced?

TLV2352IPW uses N-channel open-drain outputs for both comparators. Each output requires an external pullup resistor to establish a logic-high voltage level. This configuration enables wired-AND logic, level translation across voltage domains, and compatibility with TTL, MOS, and CMOS inputs. The datasheet specifies that pullup values must be selected to meet sink-current and rise-time requirements for the target load.

Is TLV2352IPW pin-compatible with other TSSOP-8 dual comparators?

No documented pin-to-pin compatibility exists between TLV2352IPW and other TSSOP-8 dual comparators such as LMV393IPWR or TLV3702IPWR. While all share the same 8-pin TSSOP outline, the pin functions differ - notably, TLV2352IPW assigns OUT A to Pin 1 and OUT B to Pin 7, whereas LMV393IPWR places OUT A on Pin 1 and OUT B on Pin 2. Layout redesign is required for substitution.

What is the typical supply current of TLV2352IPW at 3V operation?

The typical supply current of TLV2352IPW at 3V is 120µA, as stated in the Features list and verified in Section 5.3 (Electrical Characteristics TLV2352I) of the datasheet. This value is measured under no-load conditions with VID = 1V at 25°C. The maximum supply current across the full temperature range (–40°C to 85°C) is 350µA, making TLV2352IPW highly suitable for ultra-low-power applications.
