Product details
Overview
TLC354CPWRG4 from Texas Instruments is a LinCMOS™ quadruple differential comparator IC designed for precision voltage comparison in low-power, single- or dual-supply systems. It delivers 5 mV max input offset voltage, 5 pA typical input bias current, and operates from 1.4 V to 16 V supply - enabling use in battery-powered sensor interfaces and industrial threshold-detection circuits.
For engineers reviewing the TLC354CPWRG4 datasheet, TLC354CPWRG4 pinout, TLC354CPWRG4 application, or TLC354CPWRG4 equivalent, key selection factors include its open-drain n-channel outputs compatible with TTL/MOS/CMOS logic, ultra-low 130 µA supply current at 1.4 V, and guaranteed operation across 0°C to 70°C with TSSOP-14 packaging.
Technical Context
The TLC354CPWRG4 integrates four independent comparators on a single die using LinCMOS™ process technology, enabling high-input-impedance (>10¹² Ω) sensing without loading high-impedance sources. Each channel features rail-to-rail common-mode input range including ground and supports wired-AND logic via open-drain outputs.
It is characterized for single-supply operation from 1.4 V to 16 V or dual-supply operation with up to 18 V total differential voltage. Input offset voltage drift is ultrastable at 0.23 µV/month, and ESD protection meets 2000-V HBM per MIL-STD-833C.
Key Specifications

Applications
| Battery Voltage Monitor | Sensor Threshold Detector |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during charging/discharging to trigger cutoff or alert logic. IC Role / Device Role / Timing Role: Quadruple comparator performing simultaneous under-voltage lockout (UVLO), over-voltage protection (OVP), and charge-state window detection. Use Value: 1.4 V minimum supply allows direct operation from partially discharged cells; 5 mV offset ensures ±25 mV detection accuracy at 5 V reference. | Use Scenario: Converting analog output from temperature, pressure, or gas sensors into digital status flags. IC Role / Device Role / Timing Role: Four independent comparators implementing hysteresis-based trip points for fault, warning, nominal, and alarm bands. Use Value: 5 pA input bias prevents loading of high-Z sensor bridges; open-drain outputs interface directly to microcontroller GPIOs with configurable pull-ups. |
| Power Supply Sequencing Controller | Industrial Logic Interface Adapter |
Use Scenario: Ensuring correct power-up order across multiple rails (e.g., 12 V → 5 V → 3.3 V) in FPGA or DSP systems. IC Role / Device Role / Timing Role: Comparator channels monitor each rail's voltage and drive enable/disable signals to DC-DC converters or LDOs. Use Value: Rail-to-rail input range includes ground - enables accurate detection of 0 V to full-rail transitions; 200 ns response ensures timely sequencing control. | Use Scenario: Adapting legacy 5 V TTL or 12 V industrial logic levels to modern 3.3 V microcontrollers. IC Role / Device Role / Timing Role: Level-shifting comparator bank converting multiple high-voltage control signals into clean CMOS-compatible outputs. Use Value: Open-drain outputs allow pull-up to 3.3 V while accepting 12 V inputs; 16 mA sink capability drives optocouplers or relay drivers directly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher 25 µA supply current at 5 V; 2 mV typical offset but 7 mV max; BJT input stage. | Lacks 1.4 V low-voltage operation; unsuitable for sub-2 V battery systems. | Select LM339DR only when cost is primary and ultra-low power is not required. |
| TLC3704CDR | CMOS rail-to-rail inputs; 10 mV max offset; 100 nA supply current at 5 V; no 1.4 V rating. | Higher input offset and no guaranteed 1.4 V operation limit use in precision low-voltage sensing. | Choose TLC3704CDR for rail-to-rail input swing where supply >2.7 V and offset <10 mV is acceptable. |
Compared with LM339DR and TLC3704CDR, the TLC354CPWRG4 uniquely combines 1.4 V operation, 5 pA bias current, and 5 mV offset in a TSSOP-14 package - making it the only option for high-precision, ultra-low-power quadruple comparison below 2 V.

FAQ
What is the minimum operating voltage for the TLC354CPWRG4?
The TLC354CPWRG4 operates down to 1.4 V supply voltage, verified across the full 0°C to 70°C temperature range. This enables direct use with single alkaline or lithium coin cells without voltage boosting, and is confirmed in the Recommended Operating Conditions table of the SLCS116B datasheet.
Does the TLC354CPWRG4 support dual-supply operation?
Yes, the TLC354CPWRG4 supports dual-supply operation when the difference between VDD and VDD–/GND is between 1.4 V and 18 V. The absolute maximum ratings specify ±18 V differential input voltage, and the device functions correctly with split rails such as +5 V and –3 V, provided total differential remains within spec.
What is the input bias current specification for the TLC354CPWRG4?
The TLC354CPWRG4 has a typical input bias current of 5 pA at 25°C, with a maximum of 20 nA across the full temperature range. This ultra-low value is enabled by its LinCMOS™ input stage and is critical for interfacing with high-impedance sources like piezoelectric sensors or pH electrodes without signal degradation.
Is the TLC354CPWRG4 pin-compatible with the LM339?
Yes, the TLC354CPWRG4 in TSSOP-14 (PW) package is pin-compatible with the LM339 in the same footprint. Both share identical pin assignments for all 14 terminals, including VDD, GND, and the four IN+/IN–/OUT sets. This allows direct PCB replacement without layout changes.
What logic families are compatible with the TLC354CPWRG4 outputs?
The TLC354CPWRG4 outputs are n-channel open-drain and are explicitly rated compatible with TTL, MOS, and CMOS logic families. External pull-up resistors allow interfacing to 3.3 V, 5 V, or 12 V logic rails, and the 16 mA sink capability supports direct driving of LEDs, optocouplers, or small relays.
