Product details
Overview
TLC193MJGB from Texas Instruments is a dual micropower voltage comparator with open-drain CMOS outputs, designed for single-supply operation from 4 V to 16 V across the full military temperature range (−55°C to 125°C). 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 at 25°C - enabling precision threshold detection in high-reliability analog monitoring circuits.
For engineers reviewing the TLC193MJGB datasheet, TLC193MJGB pinout, TLC193MJGB application, or TLC193MJGB equivalent, key selection considerations include its military-grade temperature rating, ultra-low quiescent current, open-drain output compatibility with pull-up networks, and LinCMOS™ process advantages including high input impedance (>1012 Ω), low input bias current (5 pA typ), and stable offset under differential stress.
Technical Context
The TLC193MJGB implements two independent comparators on a single die using Texas Instruments' LinCMOS™ process, which integrates precision analog performance with standard CMOS low-power benefits. Its input stage provides rail-to-rail common-mode range (0 V to VDD − 1.5 V) and exceptional rejection of supply and common-mode variations (≥84 dB CMMR and kSVR).
Each comparator features an open-drain MOS output stage capable of sinking up to 20 mA, requiring external pull-up for logic-level translation. The device avoids linear-region operation in the output stage to prevent latch-up or damage, necessitating proper overdrive and load configuration per TI's test methodology.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 16 V - supports wide-input industrial/military power rails without regulation. |
| Quiescent Supply Current | 22–40 µA typ (both comparators, 25°C) - enables multi-year battery operation in remote sensors. |
| Input Offset Voltage | ≤5 mV max at 25°C; ≤10 mV max over −55°C to 125°C - ensures accurate threshold detection across full temp range. |
| Propagation Delay (tPLH) | 2.5 µs typ at 5 V, 5-mV overdrive, CL = 15 pF - balances speed and micropower for real-time level sensing. |
| Input Bias Current | 5 pA typ at 25°C; ≤30 nA max at 125°C - minimizes error in high-impedance sensor interfaces (e.g., thermistors, photodiodes). |
| Common-Mode Input Range | 0 V to VDD − 1.5 V - allows direct interfacing to unbuffered resistive dividers across wide supply voltages. |
| Output Sink Current | 20 mA max per output - drives LEDs, MOSFET gates, or logic inputs directly with appropriate pull-up. |
Pinout & Package
Ceramic Dual-In-Line Package (CDIP), JG variant, 8-pin, through-hole, hermetically sealed - rated for military temperature operation and long-term reliability in harsh environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Open-drain output of Comparator 1 - requires external pull-up to define logic HIGH level. |
| 2 | 1IN− | Inverting input of Comparator 1 - used for reference voltage or feedback connection. |
| 3 | 1IN+ | Non-inverting input of Comparator 1 - accepts signal to be compared against reference. |
| 4 | GND | Analog ground reference - must be low-impedance and decoupled near device. |
| 5 | VDD | Positive supply rail - requires 0.1-µF ceramic decoupling capacitor placed adjacent to pin. |
| 6 | 2OUT | Open-drain output of Comparator 2 - independently configurable, same electrical behavior as Pin 1. |
| 7 | 2IN− | Inverting input of Comparator 2 - electrically isolated from Comparator 1 inputs. |
| 8 | 2IN+ | Non-inverting input of Comparator 2 - supports dual-threshold or window-comparator topologies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393J | Higher quiescent current (500 µA typ), wider offset (7 mV max), commercial/industrial temp only (−25°C to 85°C). | Lacks military qualification and micropower capability - unsuitable for battery-powered or extended-temp deployments. | Select LM393J only for cost-sensitive, non-military designs where power and temperature margins are relaxed. |
| TLC393MJG | Identical pinout, package, and electrical specs - differs only in part numbering convention and internal screening level per MIL-PRF-38535. | No functional difference; both qualified to Class B (military) per same datasheet SLCS115E. | TLC393MJG is a functionally identical alternative with equivalent sourcing traceability and qualification documentation. |
Compared with LM393J, TLC193MJGB reduces supply current by >95% and extends operating temperature by 140°C; versus TLC393MJG, it shares identical performance but may differ in lot traceability and certificate-of-conformance packaging for specific procurement contracts.

FAQ
What is the maximum operating temperature range for the TLC193MJGB?
The TLC193MJGB is fully characterized and qualified for continuous operation from −55°C to +125°C, meeting MIL-PRF-38535 Class B requirements. This rating is verified across all electrical parameters including input offset voltage (≤10 mV), supply current (≤90 µA), and propagation delay (≤8 µs at 125°C), making it suitable for avionics, engine control, and space-qualified systems.
Does the TLC193MJGB require external pull-up resistors on its outputs?
Yes, the TLC193MJGB features open-drain CMOS outputs (Pins 1 and 6), which can only sink current. Each output must be connected to a pull-up resistor tied to a defined logic HIGH voltage (e.g., VDD or another rail) to establish valid HIGH-state logic levels. Typical values range from 2.2 kΩ to 10 kΩ depending on speed and drive strength requirements.
How does the LinCMOS™ process benefit the TLC193MJGB in precision applications?
The LinCMOS™ process enables the TLC193MJGB to achieve <5 pA input bias current and stable input offset voltage even under ±several volts of differential input stress - a key advantage over standard CMOS comparators. This ensures minimal measurement error in high-impedance sensor interfaces such as RTDs, strain gauges, or pH electrodes across the full military temperature range.
Can the TLC193MJGB be used with a 3-V supply?
No. The TLC193MJGB has a minimum specified supply voltage of 4 V per the recommended operating conditions table in SLCS115E. Operation below 4 V is not characterized or guaranteed - parameters like propagation delay, offset voltage, and output drive may degrade unpredictably. For 3-V operation, consider the TLC393C or TLC393I variants instead.
Is the TLC193MJGB RoHS compliant?
No. The TLC193MJGB uses a ceramic DIP (JG) package with lead (Pb) finish (SNPB), and is explicitly marked "No" for RoHS compliance in TI's official packaging addendum. It is intended for legacy military/aerospace applications where Pb-based finishes are permitted and required for solder joint reliability under thermal cycling.
