Product details
Overview
TLV2354IPWR 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 open-drain N-channel outputs compatible with TTL/MOS/CMOS logic-used in battery-powered voltage monitoring and precision threshold detection circuits.
For engineers reviewing the TLV2354IPWR datasheet, TLV2354IPWR pinout, TLV2354IPWR application, or TLV2354IPWR equivalent, key selection considerations include its 14-pin TSSOP package, –40°C to 85°C operating range, rail-to-rail common-mode input (including ground), 200 ns typical response time for TTL-level steps at 5 V, and requirement for external pullup resistors on all four open-drain outputs.
Technical Context
The TLV2354IPWR implements four independent comparators using LinCMOS™ process technology, delivering >10¹² Ω typical input impedance and enabling direct interfacing with high-impedance sensors and reference sources. Its input stage operates with common-mode voltage spanning from ground to (VDD – 1.25 V) at 3 V and up to (VDD – 1.25 V) at 5 V.
All outputs are N-channel open-drain configurations requiring external pullup resistors to define logic-high levels; this architecture supports wired-AND logic functions and mixed-voltage level interfacing. The device includes built-in ESD protection rated at 1000 V (HBM) and is characterized across –40°C to 85°C per JEDEC JESD22-A114.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 8 V - enables use in 2-cell alkaline, Li-ion, or 3.3 V/5 V systems without level-shifting. |
| Input Bias Current | 5 pA typ at 25°C - preserves accuracy in high-impedance divider networks and sensor interfaces. |
| Input Offset Voltage | 5 mV max at 25°C - ensures reliable switching within ±2.5 mV of threshold under nominal conditions. |
| Response Time | 200 ns typ for TTL-level step at VDD = 5 V - supports fast edge detection in timing-critical window comparators. |
| Output Type | Open-drain N-channel - requires external pullup; allows flexible logic-level translation and wired-AND bus configuration. |
| Common-Mode Input Range | Includes ground (0 V) - simplifies single-supply sensing of signals referenced to system ground. |

Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad not electrically connected, RoHS-compliant NiPdAu lead finish, MSL Level-1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Open-drain output of comparator A - must be pulled up externally to define logic HIGH. |
| 2 | IN– A | Inverting input of comparator A - accepts voltage below noninverting input to assert LOW output. |
| 3 | IN+ A | Noninverting input of comparator A - accepts voltage above inverting input to assert LOW output (open-drain active-low). |
| 4 | VDD+ | Positive supply rail - powers all four comparators; decoupling capacitor recommended near pin. |

| 8 | GND / VDD– | Ground reference - serves as return path for all comparators and internal circuitry. |
| 9 | OUT C | Open-drain output of comparator C - supports independent wired-AND or discrete logic interface. |
| 10 | IN– C | Inverting input of comparator C - shares same electrical characteristics as Pins 2 and 6. |
| 11 | IN+ C | Noninverting input of comparator C - matches performance of Pins 3 and 5 across temperature. |
| 12 | IN+ D | Noninverting input of comparator D - completes quad set; no internal connection to other channels. |
| 13 | IN– D | Inverting input of comparator D - fully independent; supports separate threshold configuration. |
| 14 | OUT D | Open-drain output of comparator D - enables four-channel status monitoring with minimal board area. |
Key Features
| Feature | Design Value |
|---|---|

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 (250 nA bias current); wider 2 V to 36 V supply range. | Less suitable for ultra-low-power battery systems but more tolerant of noisy industrial environments. | Select LM339DR when higher drive strength, wider supply range, or legacy footprint compatibility is required. |
| TLV3704IPWR | Lower 800 nA supply current; rail-to-rail input; push-pull output (no external pullup needed); 1.8 V min supply. | Eliminates pullup resistors and saves board space, but lacks ESD rating documentation matching TLV2354IPWR's 1000 V HBM. | Choose TLV3704IPWR for new ultra-low-power designs where layout simplicity and sub-2 V operation outweigh proven field ESD robustness. |
Compared with LM339DR and TLV3704IPWR, the TLV2354IPWR offers the optimal balance of ultra-low bias current (5 pA), validated 1000 V HBM ESD protection, and open-drain flexibility - making it preferred for precision, ground-referenced, battery-constrained applications where external pullup design control is acceptable.

FAQ
What is the maximum supply voltage for TLV2354IPWR?
The absolute maximum supply voltage for TLV2354IPWR is 8 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent 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.
Does TLV2354IPWR require external pullup resistors on its outputs?
Yes, TLV2354IPWR features open-drain N-channel outputs on all four channels, meaning each output (Pins 1, 7, 9, 14) must be connected to an external pullup resistor to a positive supply to generate a logic HIGH. Typical values range from 2.2 kΩ to 10 kΩ depending on speed and load requirements.
Can TLV2354IPWR operate with inputs at ground potential?
Yes, TLV2354IPWR supports a common-mode input voltage range that includes ground (0 V) across its full operating supply range (2 V to 8 V). This allows direct sensing of signals referenced to system ground without level-shifting circuitry - a key advantage in single-supply applications.
What is the input bias current specification for TLV2354IPWR?
The TLV2354IPWR exhibits a typical input bias current of 5 pA at 25°C, enabled by its LinCMOS™ process technology. This ultra-low value minimizes voltage errors in high-impedance source networks, such as those found in pH probes, photodiode amplifiers, and precision voltage dividers.
Is TLV2354IPWR pin-compatible with other TSSOP-14 quad comparators?
No, TLV2354IPWR is not pin-compatible with standard quad comparators like LM339 or TLC3704 due to differing pin assignments - for example, TLV2354IPWR places VDD on Pin 4 and GND on Pin 8, whereas LM339DR uses Pin 3 for VDD and Pin 12 for GND. Layout redesign is required for substitution.
