Product details
Overview
TLC3702MDRG4 from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, operating from 4 V to 16 V supply, delivering ±8 mA output drive, 2.7 μs typical propagation delay (tPLH) at 5-mV overdrive, and 100 μW typical quiescent power at 5 V - used in precision threshold detection for military-grade sensor interfaces and power-supply monitoring circuits.
For engineers reviewing the TLC3702MDRG4 datasheet, TLC3702MDRG4 pinout, TLC3702MDRG4 application, or TLC3702MDRG4 equivalent, key selection considerations include its −55°C to 125°C military temperature rating, input offset voltage ≤10 mV across full temperature range, push-pull output eliminating external pullup resistors, and compatibility with TTL logic levels despite CMOS process architecture.
Technical Context
The TLC3702MDRG4 integrates two independent comparators on a single die using Texas Instruments' LinCMOS™ process, enabling high input impedance (>10¹² Ω), ultra-low input bias current (5 pA typ at 25°C), and stable input offset voltage under large differential inputs. Its push-pull output stage directly drives capacitive loads up to 50 pF without external components while maintaining fast response.
This device replaces legacy bipolar comparators like LM339 in high-reliability systems by reducing power consumption to 1/20th while preserving comparable speed. It supports single-supply operation with common-mode input range extending to VDD − 1.5 V and features on-chip ESD protection rated to 2 kV (HBM) and 200 V (CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 16 V - enables direct integration into 5 V, 12 V, and 15 V military power rails without regulation. |
| Input Offset Voltage (max) | 10 mV over −55°C to 125°C - ensures reliable switching accuracy in wide-temperature environmental sensing. |
| Propagation Delay (tPLH) | 2.7 μs typ at 5-mV overdrive, CL = 50 pF - supports sub-microsecond threshold detection in real-time control loops. |
| Quiescent Supply Current | 90 μA max over full temperature range - sustains multi-year battery life in low-duty-cycle monitoring applications. |
| Output Drive Capability | ±20 mA per output - directly interfaces with logic inputs, LEDs, or small-signal MOSFET gates without buffering. |
| Common-Mode Input Range | 0 V to VDD − 1.5 V - allows rail-to-rail input sensing in single-supply systems with grounded references. |

Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150-mil width, RoHS-compliant, tape-and-reel (R suffix). Pin count: 8 terminals, with 2 NC (no internal connection) pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Push-pull CMOS output of comparator 1 - sinks or sources current without external pullup; compatible with TTL and CMOS logic. |
| 2 | IN1− | Inverting input of comparator 1 - high-impedance node (≥10¹² Ω); requires external hysteresis or filtering for noisy signals. |
| 3 | IN1+ | Non-inverting input of comparator 1 - accepts input voltages from 0 V to VDD − 1.5 V; supports direct connection to sensor outputs. |
| 4 | GND | Analog ground reference - must be tied to system ground plane with low-inductance path to minimize noise coupling. |
| 5 | VDD | Positive supply rail - decoupling capacitor (0.1 μF ceramic) required within 5 mm of this pin for stable operation. |
| 6 | OUT2 | Push-pull CMOS output of comparator 2 - electrically isolated from OUT1; supports independent load driving. |
| 7 | IN2− | Inverting input of comparator 2 - identical electrical characteristics to IN1−; enables dual-threshold or window-comparator configurations. |
| 8 | IN2+ | Non-inverting input of comparator 2 - fully independent of IN1+; permits simultaneous monitoring of two distinct analog signals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393AMX/NOPB | Bipolar process; higher supply current (500 μA typ); wider input offset (7 mV max at 25°C but degrades to 15 mV at 125°C). | Lacks military temp rating; not qualified below −40°C; unsuitable for avionics or downhole use. | Select when cost sensitivity outweighs power and temperature performance; verify layout for higher IDD thermal dissipation. |
| TLV3702IDR | CMOS micropower; lower IDD (20 μA typ); narrower supply range (2.7 V to 16 V); same SOIC-8 package. | Commercial/industrial grade only (−40°C to 85°C); no military qualification or extended temp testing data. | Prefer for battery-powered industrial IoT where extended temperature is unnecessary and lowest possible quiescent current is critical. |
Compared with LM393AMX/NOPB and TLV3702IDR, the TLC3702MDRG4 uniquely delivers military-grade temperature operation, LinCMOS™-enabled low-offset stability, and push-pull drive in a single SOIC-8 package - making it the only option for high-reliability embedded systems requiring guaranteed performance from −55°C to 125°C.

FAQ
What is the maximum operating temperature range for the TLC3702MDRG4?
The TLC3702MDRG4 is specified for continuous operation from −55°C to +125°C, meeting military-grade environmental requirements. This full-range qualification is confirmed in the "recommended operating conditions" table of the SLCS013E datasheet, and distinguishes it from commercial (0°C to 70°C) and industrial (−40°C to 85°C) variants of the same family. The TLC3702MDRG4 maintains all key parameters-including input offset voltage ≤10 mV and supply current ≤90 μA-within this entire span.
Does the TLC3702MDRG4 require external pullup resistors on its outputs?
No, the TLC3702MDRG4 does not require external pullup resistors because it features a push-pull CMOS output stage capable of actively sourcing and sinking current (±20 mA per output). This architecture eliminates the power loss, board space, and timing uncertainty associated with external pullups-enabling direct interfacing with TTL, CMOS, and small-signal MOSFET loads. The datasheet explicitly states this capability in the "description" section and confirms ±8 mA drive at typical conditions.
What is the input offset voltage specification for the TLC3702MDRG4 over temperature?
The TLC3702MDRG4 has a maximum input offset voltage of 10 mV across its full operating temperature range of −55°C to +125°C, as specified in the "electrical characteristics" table for the TLC3702M variant. At 25°C, the typical value is 1.2 mV, with a maximum of 5 mV. This tight offset stability is enabled by TI's LinCMOS™ process and is critical for precision threshold detection in military and aerospace applications where calibration drift must be minimized.
Can the TLC3702MDRG4 operate from a 3 V supply?
No, the TLC3702MDRG4 cannot operate from a 3 V supply. Its minimum recommended supply voltage is 4 V, as defined in the "recommended operating conditions" table for the TLC3702M grade. While the broader TLC3702 family (e.g., TLC3702C/I) supports 3 V, the M-grade variant trades low-voltage operation for enhanced high-temperature performance and military qualification. Attempting 3 V operation may result in undefined output behavior or failure to meet timing and offset specifications.
How is the TLC3702MDRG4 protected against electrostatic discharge?
The TLC3702MDRG4 incorporates Texas Instruments' patented on-chip ESD-protection circuitry, qualified to 2000 V per Human Body Model (HBM) and 200 V per Charged Device Model (CDM). This protection uses a dual-transistor shunt architecture with zener clamping (D3) and current-limiting resistors (R1, R2) to safely divert transients without introducing leakage currents that would degrade picoamp-level input bias performance. The design is validated per MIL-STD-883 test method 3015.7.
