Product details
Overview
TLV2354ID from Texas Instruments is a LinCMOS™ quadruple low-voltage differential comparator IC designed for single-supply operation down to 2 V. It delivers 240 µA typical supply current at 3 V, features 10¹² Ω typical input impedance, 5 pA typical input bias current, and 200 ns typical response time for TTL-level inputs - enabling precision threshold detection in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2354ID datasheet, TLV2354ID pinout, TLV2354ID application, or TLV2354ID equivalent, key selection considerations include its open-drain N-channel outputs requiring external pull-up resistors, ground-inclusive common-mode input range (0 V to VDD–1.25 V), –40°C to 85°C operating temperature, and SOIC-14 package compatibility with standard PCB assembly processes.
Technical Context
The TLV2354ID implements four independent comparators using Texas Instruments' LinCMOS™ process, delivering ultra-high input impedance and femtoampere-level leakage performance ideal for high-impedance source interfacing. Its open-drain output stage supports wired-AND logic and level translation across voltage domains when paired with appropriate pull-up resistors.
It operates across a 2 V to 8 V supply range and is fully characterized at both 3 V and 5 V. Input offset voltage is specified at ≤5 mV over temperature, and common-mode input range extends to ground - critical for detecting near-zero reference thresholds in single-supply systems.

Applications
| Battery Voltage Monitor | Threshold Detection in Portable Sensors |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage to trigger low-battery warning or shutdown before deep discharge. IC Role / Device Role / Timing Role: Quad comparator compares cell voltage against four precise reference thresholds (e.g., 4.2 V, 3.8 V, 3.5 V, 3.0 V) using resistor-divider networks. Use Value: Enables granular state-of-charge indication with <5 mV input offset error and no external op-amps or ADCs required. | Use Scenario: Detecting motion-triggered events in wearable accelerometers with configurable wake-up sensitivity. IC Role / Device Role / Timing Role: One channel monitors accelerometer output against programmable trip points; remaining channels handle auxiliary functions (e.g., supply OK, temp alert). Use Value: 240 µA total quiescent current extends sensor node battery life beyond 2 years while maintaining sub-millisecond response. |
| Industrial Level Translator | Wired-AND Logic Interface |
Use Scenario: Converting 0–2.5 V analog sensor outputs to clean 3.3 V logic-compatible digital flags for MCU GPIO inputs. IC Role / Device Role / Timing Role: Comparator acts as rail-to-rail input buffer with open-drain output pulled to 3.3 V, rejecting noise below hysteresis threshold. Use Value: Eliminates need for dedicated level-shifter ICs; ground-referenced input accepts unbuffered sensor signals directly. | Use Scenario: Implementing fault-aggregation bus in motor control systems where multiple safety interlocks must assert a common "STOP" signal. IC Role / Device Role / Timing Role: Four open-drain outputs tied together on shared pull-up - any active-low fault pulls bus low, triggering immediate shutdown. Use Value: Hardware-based OR logic with no software latency; 200 ns propagation ensures sub-microsecond fault response. |
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 |
|---|---|---|---|
| TLV2354IPW | TSSOP-14 package (3.0 mm × 4.4 mm), same electrical specs, RoHS-compliant NiPdAu finish. | Preferred for space-constrained PCBs; requires fine-pitch reflow profile (MSL-1, 260°C peak). | Select when board area is critical and assembly process supports TSSOP; identical functionality and temperature range (–40°C to 85°C). |
| LM339DR | Wider supply range (2 V to 36 V), higher supply current (500 µA typ), bipolar input stage (250 nA bias current), no ground-sensing input. | Suitable for industrial 12/24 V systems but lacks ultra-low leakage and true ground-referenced operation. | Choose only if higher voltage tolerance or cost sensitivity outweighs need for picoampere input bias and ground-inclusive common-mode range. |
Compared with TLV2354IPW, TLV2354ID offers identical comparator performance in a more robust SOIC package with easier hand-soldering and legacy footprint compatibility; versus LM339DR, TLV2354ID provides 50× lower input bias current and guaranteed ground-referenced operation - critical for precision low-power sensing.

FAQ
What is the maximum supply voltage for TLV2354ID?
The absolute maximum supply voltage for TLV2354ID is 8 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent device damage. For reliable long-term performance, TI recommends staying within the recommended operating range of 2 V to 8 V, with full characterization at 3 V and 5 V. The TLV2354ID maintains stable comparator function and specified parameters across this entire range.
Does TLV2354ID support rail-to-rail input operation?
TLV2354ID supports common-mode input voltages down to ground (0 V) but does not support rail-to-rail input swing up to VDD. At VDD = 3 V, the common-mode input range is 0 V to 1.75 V; at VDD = 5 V, it is 0 V to 3.75 V. This means the upper limit is VDD – 1.25 V. The TLV2354ID is optimized for ground-referenced sensing rather than full rail utilization, distinguishing it from true rail-to-rail-input comparators.
Why does TLV2354ID require an external pull-up resistor on each output?
TLV2354ID uses N-channel open-drain output transistors, which can only sink current to ground and cannot actively drive high. An external pull-up resistor is mandatory to establish a defined high logic level (e.g., 3.3 V or 5 V) and enable wired-AND functionality. Without it, outputs remain floating in the high state. The value depends on speed and load requirements - TI recommends 5.1 kΩ for typical 3 V/5 V operation with ~200 ns response.
Is TLV2354ID pin-compatible with other quad comparators like LM339?
No, TLV2354ID is not pin-compatible with LM339 or similar quad comparators. TLV2354ID uses a non-standard pinout optimized for its four independent channels in SOIC-14: pins 1–3 (Ch1), 5–7 (Ch2), 9–11 (Ch3), 12–14 (Ch4), with VDD on pin 4 and GND on pin 8. LM339 places all outputs on one side and inputs on the other. Direct replacement would require PCB redesign. Always verify pin mapping using the official TLV2354ID datasheet diagram.
What is the operating temperature range of TLV2354ID?
The TLV2354ID is rated for operation from –40°C to +85°C ambient temperature. This industrial-grade range is confirmed in the "Available Options" table and "Recommended Operating Conditions" section of the datasheet. It is distinct from the TLV2354M variant (–55°C to +125°C) and applies specifically to the "I" grade devices in D, N, PW, and Y packages. Thermal derating curves and power dissipation limits are provided for this temperature span.
