Product details
Overview
TLC3702CDR from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, 5-mV max input offset voltage at 25°C, 100 μW typical supply power at 5 V, and 2.7 μs typical propagation delay (tPLH) with 5-mV overdrive - used in battery-powered sensor threshold detection and low-power analog monitoring circuits.
For engineers reviewing the TLC3702CDR datasheet, TLC3702CDR pinout, TLC3702CDR application, or TLC3702CDR equivalent, this page delivers verified package mapping (SOIC-8), confirmed electrical specs (3–16 V single-supply, ±8 mA output drive), temperature range (0°C to 70°C), and two validated alternative comparators for commercial-grade micropower designs.
Technical Context
The TLC3702CDR implements two independent comparators on a LinCMOS™ process, enabling rail-to-rail input operation (0 V to VDD − 1.5 V) and TTL/CMOS-compatible push-pull outputs that eliminate external pullup resistors. Its architecture supports stable operation with capacitive loads up to 50 pF without oscillation.
Input stage features ultra-low bias current (5 pA typ at 25°C), high common-mode rejection (84 dB min), and 2-kV HBM ESD protection on all pins. The device operates across 3 V to 16 V supply while maintaining micropower consumption (18–40 μA total IDD at 25°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - enables direct interface with Li-ion, 5 V, and 12 V systems without level-shifting. |
| Input Offset Voltage (max) | 5 mV at 25°C - ensures reliable threshold detection within ±2.5 mV accuracy for precision sensing. |
| Propagation Delay (tPLH) | 2.7 μs typ @ 5-mV overdrive - supports fast response in window comparators and overvoltage latches. |
| Supply Current (IDD) | 18–40 μA typ (both comparators, no load) - extends battery life in always-on monitoring applications. |
| Output Drive Capability | ±8 mA - directly drives LEDs, logic inputs, or small MOSFET gates without external buffers. |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade embedded control and instrumentation environments. |
| Input Bias Current | 5 pA typ at 25°C - minimizes loading error on high-impedance sources like thermistors or photodiodes. |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel format indicated by 'R' suffix in TLC3702CDR. RoHS-compliant, 1.27 mm pitch, 4.9 mm × 3.9 mm body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Push-pull CMOS output of comparator 1 - sinks or sources current; no pullup required. |
| 2 | 1IN− | Inverting input of comparator 1 - accepts signals up to VDD − 1.5 V with minimal bias current. |
| 3 | 1IN+ | Non-inverting input of comparator 1 - supports rail-to-rail common-mode range for flexible reference design. |
| 4 | GND | Analog/digital ground reference - shared return path for both comparators and supply. |
| 5 | VDD | Positive supply input - powers both comparators; accepts 3–16 V with internal ESD protection. |

Key Features
| Feature | Design Value |
|---|---|

Applications
| Battery Voltage Monitor | Over-Temperature Protection |
|---|---|
|
Use Scenario: Detecting low-battery condition in handheld medical devices using a resistive divider off a 3.7 V Li-ion cell. IC Role / Device Role / Timing Role: Comparator 1 compares divided battery voltage against 1.25 V reference; output triggers shutdown logic.

IC Role / Device Role / Timing Role: Comparator 2 compares thermistor-derived voltage against fixed reference; output drives latch circuit. Use Value: Rail-to-rail input range accommodates full thermistor swing; ±8 mA drive directly energizes relay coil. |
| Window Comparator | Power Supply Sequencing |
|
Use Scenario: Validating that 5 V rail stays within 4.75–5.25 V tolerance during FPGA configuration. IC Role / Device Role / Timing Role: TLC3702CDR's dual comparators implement upper/lower thresholds; ANDed outputs signal valid window. Use Value: Matched offset and gain between channels ensure symmetrical hysteresis; 2.7 μs delay enables real-time validation. |
Use Scenario: Enforcing correct power-up order for multi-rail SoC (e.g., 1.2 V before 3.3 V) in telecom baseband modules. IC Role / Device Role / Timing Role: Each comparator monitors one rail; outputs enable enable pins of downstream regulators via open-drain logic. Use Value: Push-pull outputs eliminate pullup resistors on sequencing lines - reducing component count and layout complexity. |
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 | Open-collector output; requires external pullup; higher supply current (500 μA typ); 2-mV offset (typ) | Less suitable for capacitive loads or low-power sleep modes due to pullup leakage and higher IDD | Select LM393DR only when legacy open-collector interface or cost sensitivity outweighs micropower needs. |
| TLV3702IDR | Lower supply current (1.6 μA typ); rail-to-rail input; same SOIC-8 package; 3.5-mV offset (max) | Better for sub-μA battery life but limited to 5.5 V supply - not compatible with 12 V or 16 V systems | Choose TLV3702IDR for ultra-low-power <5 V applications; retain TLC3702CDR for wider supply range and proven 3–16 V operation. |
Compared with LM393DR and TLV3702IDR, the TLC3702CDR uniquely balances wide supply range (3–16 V), micropower operation (18–40 μA), and push-pull drive - making it optimal for commercial-grade systems requiring flexibility, reliability, and minimal external components.

FAQ
What is the maximum supply voltage for the TLC3702CDR?
The absolute maximum supply voltage for the TLC3702CDR is 18 V, but the recommended operating range is 3 V to 16 V. Operation within this 3–16 V window ensures specified performance including input offset voltage, propagation delay, and output drive capability. Exceeding 16 V may degrade long-term reliability even if within absolute ratings. The TLC3702CDR maintains full functionality across this range without external regulation.
Does the TLC3702CDR require external pullup resistors on its outputs?
No, the TLC3702CDR does not require external pullup resistors because it features push-pull CMOS outputs capable of sourcing and sinking up to ±8 mA. This architecture eliminates the power loss, board space, and component cost associated with pullup resistors - a key differentiator from open-collector comparators like the LM393. The TLC3702CDR drives capacitive loads directly while maintaining specified 2.7 μs propagation delay.
What is the input offset voltage specification for the TLC3702CDR?
The TLC3702CDR has a maximum input offset voltage of 5 mV at 25°C and 6.5 mV across the full 0°C to 70°C commercial temperature range. This value is guaranteed per TI datasheet SLCS013E and applies to both comparators independently. The low offset enables precise threshold detection in applications such as battery voltage monitoring and sensor signal conditioning where accuracy within ±2.5 mV is required.
Can the TLC3702CDR operate from a 3.3 V supply?
Yes, the TLC3702CDR is fully specified to operate from a 3.3 V supply - falling within its 3 V to 16 V recommended range. At 3.3 V, it delivers 18–40 μA supply current, 5-mV max offset, and maintains TTL/CMOS-compatible output levels (VOH ≥ 2.8 V, VOL ≤ 300 mV). This makes the TLC3702CDR suitable for modern low-voltage embedded systems interfacing with 3.3 V microcontrollers and logic families.
Is the TLC3702CDR pin-compatible with other dual comparators in SOIC-8?
The TLC3702CDR uses the industry-standard SOIC-8 pinout for dual comparators (1OUT, 1IN−, 1IN+, GND, VDD, 2OUT, 2IN−, 2IN+), matching LM393, TLV3702, and many others. However, functional compatibility depends on output type: TLC3702CDR's push-pull outputs differ from LM393's open-collector outputs, so direct substitution requires verifying load interface requirements. The TLC3702CDR pinout is identical, but system-level behavior must be validated.
