Product details
Overview
TLV2354IDR from Texas Instruments is a quadruple low-voltage differential comparator IC designed for single-supply operation down to 2 V, featuring 240 µA typical supply current at 3 V, 5 pA typical input bias current, and rail-to-rail common-mode input range including ground. It delivers 200 ns typical response time for TTL-level input steps and drives TTL/MOS/CMOS loads via open-drain N-channel outputs - used in battery-powered sensor threshold detection and precision level-shifting circuits.
For engineers reviewing the TLV2354IDR datasheet, TLV2354IDR pinout, TLV2354IDR application, or TLV2354IDR equivalent, key selection considerations include its LinCMOS™ high-impedance input (10¹² Ω typ), wide 2–8 V supply range, –40°C to 85°C operating temperature, open-drain output architecture requiring external pull-up, and SOIC-14 package compatibility with standard PCB layouts.
Technical Context
The TLV2354IDR implements four independent comparators using Texas Instruments' LinCMOS™ process, enabling ultra-low input bias current and high input impedance critical for interfacing with high-impedance sensors and reference sources. Its open-drain outputs support wired-AND logic and flexible voltage-level translation via external pull-up resistors.
It operates across 2 V to 8 V supply rails and is fully characterized at both 3 V and 5 V. The device supports common-mode input voltages extending to ground and up to VDD – 1.25 V (e.g., 1.75 V at VDD = 3 V), with input offset voltage limited to 5 mV max at 25°C and 7 mV over full temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3704IDR | Higher speed (1.5 µs max propagation delay), rail-to-rail input, push-pull output - no external pull-up needed. | Preferred where fast response and simplified output drive are required; less suitable for wired-AND or multi-voltage translation. | Select TLV3704IDR when push-pull outputs and faster settling outweigh ultra-low IIB requirements. |
| LM339DR | Wider supply range (2–36 V), higher IIB (250 nA typ), slower response (~1.3 µs), same open-drain output. | Better suited for industrial 12/24 V systems; not recommended for sub-3 V or high-impedance sensor interfaces. | Choose LM339DR for legacy 5 V+ designs or cost-sensitive applications where input bias current >100 pA is acceptable. |
Compared with TLV2354IDR, TLV3704IDR offers faster switching and integrated output drivers but sacrifices femtoampere-level input bias performance; LM339DR provides broader voltage tolerance and lower unit cost but lacks the LinCMOS™ input impedance essential for precision low-current sensing.

FAQ
What is the maximum supply voltage for TLV2354IDR?
The absolute maximum supply voltage for TLV2354IDR is 8 V. Operating continuously above this limit risks permanent damage. The recommended operating range is 2 V to 8 V, with full characterization at 3 V and 5 V. At 8 V, ensure thermal dissipation remains within the SOIC-14 package rating (494 mW at 85°C ambient) and that input/output voltage limits - such as VI (–0.3 V to 8 V) and VO (≤8 V) - are not exceeded. TLV2354IDR must never be subjected to supply transients exceeding 8 V, even momentarily.
Does TLV2354IDR require external pull-up resistors on its outputs?
Yes, TLV2354IDR requires external pull-up resistors on all four open-drain outputs (pins 1, 7, 9, 14). Its N-channel output transistors can only sink current; they cannot source current to produce a logic-high level. A pull-up resistor to the desired logic rail (e.g., 3.3 V or 5 V) defines the high-state voltage and determines rise time based on RC time constant. Typical values range from 2.2 kΩ to 10 kΩ depending on speed and load requirements. Without pull-ups, outputs remain floating or weakly pulled low through leakage, rendering TLV2354IDR nonfunctional in most digital interface roles.
What is the input common-mode voltage range of TLV2354IDR?
The input common-mode voltage range of TLV2354IDR extends from ground (0 V) to VDD – 1.25 V - for example, 0 V to 1.75 V at VDD = 3 V and 0 V to 3.75 V at VDD = 5 V. This rail-to-ground capability enables direct interfacing with ground-referenced sensors and single-supply signal chains without level-shifting circuitry. The specification holds across the full operating temperature range (–40°C to 85°C) and is validated per the datasheet's VICR test conditions. Inputs biased outside this range may cause incorrect output states or increased offset error.
Can TLV2354IDR operate from a 1.8 V supply?
No, TLV2354IDR is not specified or guaranteed to operate from a 1.8 V supply. Its minimum recommended supply voltage is 2 V, and electrical characteristics - including input offset voltage, response time, and output drive strength - are only characterized from 2 V upward. Below 2 V, functionality is undefined: the internal LinCMOS™ circuitry may fail to bias correctly, resulting in erratic output behavior, increased propagation delay, or complete failure to switch. For 1.8 V systems, consider purpose-designed comparators such as TLV3701 or TLV7011, which are explicitly rated down to 1.4 V or 1.6 V.
Is TLV2354IDR pin-compatible with other TI quad comparators like LM339?
No, TLV2354IDR is not pin-compatible with LM339 or LM239. While both are quad comparators in 14-pin packages, their pinouts differ significantly: TLV2354IDR uses a symmetrical layout with VDD+ on pin 4 and GND on pin 8, whereas LM339 places VCC on pin 16 and GND on pin 4 (in PDIP-14) or pin 8 (in SOIC-14), with different output and input assignments. Substituting TLV2354IDR for LM339 without PCB revision will result in incorrect power connections, reversed inputs, and non-functional outputs. Always verify pin mapping using official TI datasheets before replacement.
