Product details
Overview
TLV2354IPW from Texas Instruments is a quadruple low-voltage differential comparator IC in TSSOP-14 package, operating from 2 V to 8 V supply, featuring 240 µA typical supply current at 3 V, 5 pA typical input bias current, and open-drain N-channel outputs requiring external pull-up resistors. It is designed for single-supply sensor interface and level-detection applications in battery-powered instrumentation.
For engineers reviewing the TLV2354IPW datasheet, TLV2354IPW pinout, TLV2354IPW application, or TLV2354IPW equivalent, this page delivers verified specifications, exact TSSOP-14 terminal mapping, real-world use cases in low-power analog monitoring, and two validated alternative comparators with documented functional trade-offs.
Technical Context
The TLV2354IPW implements four independent comparators using LinCMOS™ process technology, enabling >10¹² Ω typical input impedance and rail-to-rail common-mode input range including ground. Its open-drain outputs support wired-AND logic and mixed-voltage interfacing with TTL, MOS, and CMOS loads.
Characterized over –40°C to 85°C, it delivers 200 ns typical propagation delay for TTL-level input steps at 5 V supply and maintains 5 mV max input offset voltage at 25°C - critical for precision threshold detection in portable medical and industrial sensing systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher 2 mA typical supply current; bipolar input stage (250 nA bias current); push-pull outputs require no pull-up. | Less suitable for ultra-low-power battery systems; better for high-speed (>1 µs) industrial control where speed outweighs current draw. | Select LM339DR only when board space allows larger SOIC-14 and system power budget permits 8× higher quiescent current. |
| TLV3704IPW | Lower 850 nA max input bias current; rail-to-rail input; 1.8 V min supply; integrated hysteresis option; same TSSOP-14 footprint. | Better for sub-2 V systems and precision sensor front-ends requiring <100 pA bias; not qualified for –40°C to 85°C industrial temp range. | Choose TLV3704IPW for next-gen designs needing lower voltage operation and tighter bias specs, accepting narrower temperature qualification. |
Compared with LM339DR and TLV3704IPW, the TLV2354IPW offers optimal balance of ultra-low bias current (5 pA), proven industrial temperature range (–40°C to 85°C), and mature TSSOP-14 manufacturability - making it preferred for cost-sensitive, long-lifecycle battery-powered equipment.

FAQ
What is the maximum operating temperature range for the TLV2354IPW?
The TLV2354IPW is fully characterized for operation from –40°C to +85°C ambient temperature. This industrial-grade rating is confirmed in the "Recommended Operating Conditions" table of the official SLCS012C datasheet and applies specifically to the PW-package variant. Exceeding this range may degrade input offset voltage and propagation delay performance.
Does the TLV2354IPW require external pull-up resistors on its outputs?
Yes, the TLV2354IPW features N-channel open-drain outputs that cannot source current. Each output (pins 1, 3, 8, 11) must be connected to a pull-up resistor tied to a defined voltage rail (e.g., VDD or another logic supply). Typical values range from 2.2 kΩ to 10 kΩ depending on rise time and load requirements. The TLV2354IPW datasheet explicitly states this requirement in the device description section.
Can the TLV2354IPW operate from a 1.8 V supply?
No, the TLV2354IPW has a minimum specified supply voltage of 2 V per the "Recommended Operating Conditions" table in SLCS012C. Operation below 2 V is not guaranteed and may result in failure to switch, increased propagation delay, or undefined output states. For 1.8 V systems, consider the TLV3704IPW, which is rated down to 1.8 V and shares the same TSSOP-14 package.
What is the input offset voltage specification for the TLV2354IPW at 85°C?
At full temperature range (–40°C to +85°C), the TLV2354IPW has a maximum input offset voltage of 7 mV, as specified in the "Electrical Characteristics" table for TLV2354I under "Full range" test conditions. This value is measured at VDD = 3 V and VDD = 5 V and reflects worst-case drift across the industrial temperature span - critical for maintaining threshold accuracy in thermally varying environments.
Is the TLV2354IPW pin-compatible with other TSSOP-14 quad comparators?
The TLV2354IPW uses a standard TSSOP-14 pinout matching industry conventions for quad comparators (e.g., inputs and outputs arranged per channel), but it is not pin-compatible with LM339 variants due to differing power pin locations and output structures. Always verify pin mapping using the "TLV2354I PW PACKAGE (TOP VIEW)" diagram in the SLCS012C datasheet before PCB layout.
