Product details
Overview
TLC3702CD from Texas Instruments is a dual micropower LinCMOS™ voltage comparator IC designed for single-supply operation (3 V to 16 V), delivering ±8 mA push-pull CMOS output drive without external pullup resistors, 2.7 μs typical propagation delay (tPLH) with 5-mV overdrive, and ultra-low 100 μW typical supply power at 5 V - used in battery-powered sensor threshold detection and precision level-shifting circuits.
For engineers reviewing the TLC3702CD datasheet, TLC3702CD pinout, TLC3702CD application, or TLC3702CD equivalent, key selection considerations include its commercial-temperature-rated (0°C to 70°C) D-package SOIC-8 form factor, rail-to-rail input compatibility up to VDD − 1.5 V, and direct TTL/CMOS logic interfacing capability enabled by its push-pull output stage.
Technical Context
The TLC3702CD implements two independent comparators using Texas Instruments' LinCMOS™ process, which combines high-input-impedance (>1012 Ω), picoamp-level input bias current (5 pA typ at 25°C), and stable input offset voltage (1.2–5 mV max at 25°C) - enabling reliable DC-coupled sensing in low-power systems. Its architecture eliminates need for external pullup resistors via integrated push-pull outputs, reducing board area and power overhead.
It operates across 3 V–16 V supply range with guaranteed performance over 0°C to 70°C, supports differential input voltages up to ±18 V, and features on-chip ESD protection rated to 2 kV HBM - making it suitable for industrial control interfaces where transient immunity and supply flexibility are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - enables direct use with Li-ion, 5 V, and 12 V rails without regulation. |
| Quiescent Supply Current | 18–40 μA (both comparators, 25°C) - supports multi-year battery life in always-on monitoring nodes. |
| Propagation Delay (tPLH/tPHL) | 2.7 μs / 2.3 μs typ (5-mV overdrive, CL = 50 pF) - sufficient for kHz-range window comparators and PWM feedback. |
| Input Offset Voltage | 1.2–5 mV (25°C), ≤6.5 mV (0°C to 70°C) - ensures accurate threshold detection down to ~5 mV resolution. |
| Output Drive Capability | ±8 mA (IO), push-pull CMOS - directly drives LEDs, logic inputs, or small MOSFET gates without external components. |
| Input Common-Mode Range | 0 V to VDD − 1.5 V - supports sensing near ground or rail in single-supply configurations. |

Use Scenario: Monitoring motor winding temperature and supply rail undervoltage in PLC I/O modules. IC Role / Device Role / Timing Role: Compares analog sensor outputs against precision reference voltages to assert fault flags within 3 μs. Use Value: Input common-mode range to VDD − 1.5 V allows direct connection to 12 V rail-sensed signals; ±8 mA drive activates optocouplers without buffers. |
| Power Supply Sequencing Control | LED Status Indication Logic |
|
Use Scenario: Validating correct startup order of multiple DC/DC converters in telecom base station power subsystems. IC Role / Device Role / Timing Role: Each comparator monitors a different rail voltage, asserting enable signals only when thresholds are met. Use Value: 3 V–16 V supply range accommodates 3.3 V, 5 V, and 12 V rails in one part; 2.7 μs response ensures tight sequencing windows. |
Use Scenario: Driving bi-color LED indicators based on system state (e.g., green = OK, red = fault) in embedded controllers. IC Role / Device Role / Timing Role: One comparator controls green LED anode, the other controls red LED cathode via open-drain emulation. Use Value: Push-pull outputs source/sink 8 mA - sufficient for bright LED drive without current-limiting resistors on both sides. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Open-collector output, higher 1 mA typical supply current, wider −25°C to 85°C temp range. | Requires external pullup resistor; less suitable for low-power or space-constrained designs. | Select LM393DR only if legacy open-collector interface or extended temperature range is mandatory. |
| TLC372CDR | Same LinCMOS™ process, identical pinout and specs, but offered in tape-and-reel (R suffix) packaging. | No functional difference - differs only in packaging format and reel orientation. | Choose TLC372CDR for automated SMT assembly; TLC3702CD remains optimal for manual prototyping or small-batch use. |
Compared with LM393DR and TLC372CDR, the TLC3702CD offers lower power consumption and integrated push-pull drive - eliminating BOM cost and layout area associated with pullup resistors, while maintaining full pin compatibility with TLC372 variants.

FAQ
What is the maximum supply voltage for the TLC3702CD?
The TLC3702CD supports a supply voltage range of 3 V to 16 V under recommended operating conditions. Its absolute maximum rating is 18 V, but sustained operation above 16 V may compromise reliability or parametric guarantees. Always refer to the "Recommended Operating Conditions" table in the SLCS013E datasheet for design margin guidance. The TLC3702CD maintains full functionality across this range, including input common-mode coverage to VDD − 1.5 V.
Does the TLC3702CD require external pullup resistors on its outputs?
No, the TLC3702CD does not require external pullup resistors because it features a push-pull CMOS output stage capable of sourcing and sinking up to ±8 mA. This architecture eliminates the power loss and board space associated with pullup resistors while enabling direct interfacing with TTL and CMOS logic. The TLC3702CD achieves its specified 2.7 μs propagation delay without any external components on the output pins.
What is the operating temperature range of the TLC3702CD?
The TLC3702CD is characterized for operation over the commercial temperature range of 0°C to 70°C. This specification is explicitly defined in the "Available Options" table and "Recommended Operating Conditions" section of the SLCS013E datasheet. It is not rated for extended industrial (−40°C to 85°C) or military (−55°C to 125°C) ranges - those apply only to the TLC3702ID and TLC3702MD variants, respectively.
Can the TLC3702CD drive capacitive loads directly?
Yes, the TLC3702CD is explicitly designed to drive capacitive loads directly without external compensation. Its push-pull output stage delivers stable 2.7 μs propagation delay with 50 pF load capacitance (including probe and jig effects), as verified in the "Switching Characteristics" table. This capability supports direct connection to microcontroller inputs, ADC sample-and-hold networks, and small gate-driven MOSFETs without added RC filtering.
How does the input offset voltage of the TLC3702CD compare across temperature?
The TLC3702CD exhibits a maximum input offset voltage of 5 mV at 25°C and ≤6.5 mV across its full 0°C to 70°C operating range. This stability is enabled by Texas Instruments' LinCMOS™ process, which minimizes thermal drift - confirmed by Figure 8 (offset distribution) and Figure 10 (CMRR vs temperature) in the SLCS013E datasheet. The TLC3702CD's offset remains well within 10 mV even at temperature extremes, supporting reliable DC threshold detection.
