Product details
Overview
TLC393IPWRG4 from Texas Instruments is a dual micropower voltage comparator with open-drain CMOS outputs, designed for single-supply operation from 3 V to 16 V. It delivers 110 µW typical supply power at 5 V, 2.5 µs typical propagation delay (tPLH) with 5-mV overdrive, and ≤5 mV input offset voltage across −40°C to 85°C - enabling precision threshold detection in battery-powered sensor interfaces and industrial monitoring systems.
For engineers reviewing the TLC393IPWRG4 datasheet, TLC393IPWRG4 pinout, TLC393IPWRG4 application, or TLC393IPWRG4 equivalent, key selection considerations include its industrial-temperature-rated LinCMOS™ architecture, rail-to-rail common-mode input range (0 V to VDD − 1.5 V), low 22–65 µA total supply current, and compatibility with pull-up loads up to 16 V.
Technical Context
The TLC393IPWRG4 implements two independent comparators using Texas Instruments' LinCMOS™ process, delivering high input impedance (>1012 Ω), ultra-low input bias current (5 pA typ at 25°C), and stable input offset voltage (≤7 mV max over −40°C to 85°C). Its open-drain output stage supports flexible interfacing to TTL, CMOS, or higher-voltage logic via external pull-up.
It operates with no phase reversal under common-mode stress and maintains 84 dB common-mode rejection ratio (CMMR) and 85 dB supply-voltage rejection ratio (kSVR) across temperature - critical for reliable sensing in noisy industrial environments where input signals may drift near supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - enables direct interface with 3.3 V, 5 V, and 12 V systems without level-shifting. |
| Supply Current (both comparators) | 22–65 µA - supports multi-year battery life in always-on monitoring nodes. |
| Input Offset Voltage (max) | 7 mV over −40°C to 85°C - ensures accurate 10-mV-level threshold detection without calibration. |
| Propagation Delay (tPLH, 5-mV overdrive) | 2.5 µs typ - provides sub-µs response for fast fault detection in motor control or power sequencing. |
| Common-Mode Input Range | 0 V to VDD − 1.5 V - allows direct sensing of signals down to ground, including 0–5 V analog sensor outputs. |
| Output Type | Open-drain CMOS - permits wired-OR logic, mixed-voltage interfacing, and pull-up to 16 V. |
| ESD Protection | On-chip ESD protection per MIL-STD-883C, Method 3015.2 (2000 V) - reduces need for external TVS in board-level ESD design. |
Pinout & Package
TLC393IPWRG4 is housed in an 8-pin TSSOP (PW) package, 3.0 mm × 4.4 mm, 0.65 mm pitch, RoHS-compliant with NiPdAu lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | 1IN− | Inverting input of Comparator 1 - high-impedance node; bias current ≤0.6 nA at 85°C. |
| 3 | 1IN+ | Non-inverting input of Comparator 1 - accepts common-mode voltages from 0 V to VDD − 1.5 V. |
| 4 | GND | Analog/digital ground reference - must be low-impedance; decoupling capacitor required. |
| 5 | VDD | Positive supply rail - supports 3–16 V; internal ESD protection active up to ±18 V differential. |
| 6 | 2OUT | Open-drain output of Comparator 2 - independently controllable; electrically isolated from 1OUT. |

Applications
| Battery-Powered Sensor Node | Industrial Power Sequencing |
|---|---|
|
Use Scenario: Monitoring Li-ion cell voltage and temperature in a wireless IoT sensor node with 10-year battery life target. IC Role / Device Role / Timing Role: Dual comparator performs low-battery cutoff (1IN+) and overtemperature alert (2IN+), each driving separate MCU interrupt lines via open-drain outputs. Use Value: 22 µA typical supply current extends battery life; rail-to-rail input range captures full 0–4.2 V cell voltage without signal conditioning. |
Use Scenario: Controlling startup order of FPGA, DSP, and analog subsystems in a programmable logic controller (PLC). IC Role / Device Role / Timing Role: TLC393IPWRG4 compares 3.3 V and 1.2 V supply rails against precision references; outputs enable sequencer ICs only after both rails stabilize. Use Value: 7 mV max offset ensures accurate 1% threshold detection; 2.5 µs response guarantees sub-millisecond fault isolation during power-up. |
| Motor Overcurrent Protection | Enhanced Supply Supervisor |
|
Use Scenario: Detecting winding short-circuit in a 24 V brushed DC motor by monitoring shunt voltage during commutation. IC Role / Device Role / Timing Role: One comparator monitors shunt voltage against 50 mV trip level; second comparator validates supply integrity before enabling H-bridge driver. Use Value: Open-drain outputs interface directly to 24 V gate driver enable inputs; 20 mA sink capability drives logic-level MOSFET gates without buffer. |
Use Scenario: Providing early power-fail warning and reset assertion for a microcontroller in a smart meter operating from 12 V unregulated input. IC Role / Device Role / Timing Role: First comparator detects 12 V rail drop below 10.8 V; second monitors 5 V regulated output and asserts reset if <4.75 V. Use Value: −40°C to 85°C rating ensures reliability in outdoor meter enclosures; on-chip ESD protection reduces BOM count vs. discrete protection diodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Higher supply current (500 µA typ), wider offset spread (±7 mV), no guaranteed 85°C performance. | Limited to commercial-temperature designs; unsuitable for extended industrial ambient conditions. | Select LM393DR only for cost-sensitive, non-temperature-critical applications where power budget >100 µA is acceptable. |
| TLC3702CDR | Push-pull outputs (no external pull-up needed), faster tPLH (1.5 µs typ), but higher IDD (120 µA typ) and narrower VDD range (3–16 V same). | Preferred where drive strength and speed outweigh power savings; incompatible with wired-OR bus topologies. | Choose TLC3702CDR when driving heavy capacitive loads or requiring immediate logic-level transitions without external components. |
Compared with LM393DR and TLC3702CDR, the TLC393IPWRG4 uniquely balances ultra-low power (22 µA), industrial temperature qualification, and open-drain flexibility - making it optimal for long-life, mixed-voltage, and noise-immune sensing where component count and thermal margin are critical.

FAQ
What is the maximum supply voltage for the TLC393IPWRG4?
The TLC393IPWRG4 supports a supply voltage range of 3 V to 16 V, with absolute maximum rating of 18 V on VDD. Operation above 16 V is not recommended and may cause parametric degradation or functional failure. The device is rated for continuous operation up to 16 V across its full industrial temperature range of −40°C to 85°C, as confirmed in the SLCS115E datasheet Section "Recommended Operating Conditions".
Does the TLC393IPWRG4 have rail-to-rail input capability?
The TLC393IPWRG4 does not support true rail-to-rail input - its common-mode input voltage range is specified as 0 V to VDD − 1.5 V at −40°C to 85°C. This means the inputs can swing down to ground but must remain at least 1.5 V below VDD. For example, at VDD = 5 V, valid input range is 0 V to 3.5 V. This limitation is inherent to the LinCMOS™ input stage and is documented in the "Electrical Characteristics" tables for TLC393I.
Can the TLC393IPWRG4 outputs drive a 12 V logic input directly?
Yes - the TLC393IPWRG4 features open-drain CMOS outputs rated for up to 16 V, allowing direct connection to 12 V logic inputs when paired with an external pull-up resistor to 12 V. Each output can sink up to 20 mA, supporting standard TTL or CMOS loads. This eliminates level-shifting circuitry and is explicitly validated in the "Absolute Maximum Ratings" and "Electrical Characteristics" sections of the datasheet.
What is the input offset voltage specification for the TLC393IPWRG4 over temperature?
The TLC393IPWRG4 has a maximum input offset voltage of 7 mV over its full operating temperature range of −40°C to 85°C, as specified in the "Electrical Characteristics" table for TLC393I. At 25°C, typical offset is 1.4 mV with a maximum of 5 mV. This tight offset ensures reliable detection of small differential signals (e.g., 10 mV thresholds) without trimming, critical for precision supervisory and sensor interface applications.
Is the TLC393IPWRG4 pin-compatible with the LM393?
No - while functionally similar, the TLC393IPWRG4 is not pin-compatible with the LM393. The TLC393IPWRG4 uses an 8-pin TSSOP (PW) package with pinout: 1OUT, 1IN−, 1IN+, GND, VDD, 2OUT, 2IN−, 2IN+. The LM393 in SOIC-8 uses: OUT1, IN1−, IN1+, VCC, GND, OUT2, IN2−, IN2+. Pin assignments for power and ground differ, and output/inverting/non-inverting terminals are rearranged - requiring PCB layout revision for substitution.
