Product details
Overview
JL193BGA from Texas Instruments is a military-grade dual precision voltage comparator in TO-99 metal can package, featuring 5 mV max input offset voltage at 25°C, 0.4 mA supply current independent of supply voltage, and input common-mode range extending to ground-enabling accurate zero-crossing detection in single-supply industrial sensor interfaces.
For engineers reviewing the JL193BGA datasheet, JL193BGA pinout, JL193BGA application, or JL193BGA equivalent, this device supports high-reliability analog threshold detection in aerospace power monitoring, radiation-hardened instrumentation, and legacy MIL-STD-883 Class B embedded control systems where rail-to-ground sensing and low quiescent current are critical.
Technical Context
The JL193BGA implements two independent open-collector NPN output comparators with PNP input stages, enabling operation from single supplies (5–36 VDC) or split supplies (±2.5 V to ±18 V). Its input stage allows common-mode voltage down to −0.3 V, supporting ground-referenced signal conditioning without level-shifting circuitry.
Each comparator delivers 5 µs typical response time at 5 mV overdrive into 5.1 kΩ load, with 76 dB common-mode rejection and 80 dB channel separation. The uncommitted collector outputs support wired-OR logic, direct TTL/CMOS interfacing, and programmable pull-up to any compatible rail within the supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.0 VDC to 36 VDC single supply; ±2.5 VDC to ±18 VDC dual supply - enables direct integration into legacy 28 V aircraft bus or ±15 V test equipment without regulation. |
| Input Offset Voltage | ±5 mV max at 25°C - ensures ≤10 mV total error band for 12-bit-equivalent threshold accuracy in precision limit detection. |
| Supply Current | 0.4 mA typ, independent of supply voltage - supports battery-backed operation and reduces thermal loading in sealed enclosures. |
| Input Bias Current | ±100 nA max - permits use with high-impedance sensor sources (e.g., thermocouples, photodiodes) without significant error. |
| Output Saturation Voltage | 250 mV typ at 4 mA sink - guarantees robust low-state margin for 3.3 V or 5 V logic families under full load. |
| Operating Temperature | −55°C to +125°C - qualified per MIL-STD-883 Group A testing for sustained performance in extreme environmental conditions. |
| Input Common-Mode Range | Includes ground (−0.3 V min) - eliminates need for negative bias or level-shifters when monitoring signals referenced to system ground. |
Pinout & Package
TO-99 metal can package (LMC0008A outline), 8-pin, hermetically sealed, with center tab electrically connected to Pin 4 (V−). Package height ≤5.72 mm, lead diameter ≤1.397 mm, and JEDEC-standard 20-unit tray packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Comparator A) | Accepts reference or feedback signal; supports differential input voltage up to full supply rail. |
| 2 | Non-Inverting Input (Comparator A) | Accepts sensed signal; common-mode range includes ground for true single-supply zero-crossing capability. |
| 3 | Output (Comparator A) | Open-collector NPN - requires external pull-up; sinks up to 16 mA; enables wired-OR with other comparators. |
| 4 | V− (Negative Supply / Ground) | Reference node for dual supply; tied to case tab - must be connected to system ground or negative rail for thermal and EMI control. |
| 5 | V+ (Positive Supply) | Primary power input; accepts 5–36 VDC; supply current independent of voltage magnitude. |
| 6 | Non-Inverting Input (Comparator B) | Independent second channel input; identical electrical specs to Pin 2 - enables dual-threshold or window detection. |
| 7 | Inverting Input (Comparator B) | Second channel reference input; fully isolated from Channel A - supports 80 dB channel separation. |
| 8 | Output (Comparator B) | Second open-collector output; electrically isolated but thermally coupled - enables independent logic interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Ground-sensing input stage | Common-mode range extends to −0.3 V - enables direct monitoring of 0 V–referenced transducer outputs without external bias. |
| Single-supply operation | Functional from 5 VDC only - eliminates need for dual-rail power supplies in space-constrained avionics modules. |
| Low-power open-collector outputs | 0.4 mA total supply current with both outputs active - extends battery life in portable test equipment. |
| MIL-STD-883 qualified | Full Group A testing across −55°C to +125°C - ensures reliability in launch vehicle telemetry and satellite subsystems. |
| Logic-family compatibility | Output compatible with TTL, DTL, ECL, MOS, and CMOS - simplifies interface design without level translators. |

IC Role / Device Role / Timing Role: Direct drop-in functional replacement maintaining original PCB layout and calibration points. Use Value: Identical TO-99 pinout, electrical specs, and MIL-STD-883 qualification ensure zero redesign effort and full compliance with legacy configuration management. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM193JG | Same die, ceramic DIP-8 package; no metal can shielding; θJA = 146°C/W (still air) | Lacks hermetic seal and EMI shielding; unsuitable for high-radiation or high-vibration environments | Select JL193BGA for flight-critical or sealed-housing deployments; LM193JG only for bench-test or non-mission-critical use. |
| LM2903JG | Higher offset (7 mV max); wider temp range (−65°C to +150°C); same TO-99 footprint but different internal trimming | Lower precision but extended cold survival; not MIL-STD-883 Group A qualified | Use LM2903JG only when extreme low-temp operation is required and ±7 mV offset is acceptable; JL193BGA preferred for precision thresholding. |
Compared with LM193JG and LM2903JG, JL193BGA uniquely combines MIL-STD-883 Group A qualification, 5 mV max offset, and hermetic TO-99 packaging - making it the sole option for new designs requiring certified reliability in defense electronics and space-qualified subsystems.

FAQ
What is the maximum differential input voltage specification for JL193BGA?
The JL193BGA supports a differential input voltage range equal to the power supply voltage, with absolute maximum rating of 36 V. This allows direct comparison of signals spanning the full supply rail without external attenuation, as confirmed in the Absolute Maximum Ratings table of the SNOSAN2A datasheet.
Does JL193BGA require external pull-up resistors on its outputs?
Yes, JL193BGA features open-collector NPN outputs that require external pull-up resistors to define the logic-high state. The output transistor sinks current only; no internal pull-up is provided. Pull-up voltage may be any rail within the device's supply range (5–36 VDC), as stated in the "Output Voltage Compatible with TTL, DTL, ECL, MOS and CMOS Logic Systems" feature.
Is JL193BGA pin-compatible with commercial-grade LM193 variants?
Yes, JL193BGA uses the standard TO-99 (LMC0008A) 8-pin metal can package with identical pinout to LM193JG and LM193H. Pin assignments for V+, V−, inputs, and outputs match exactly - enabling mechanical and electrical interchangeability in existing layouts, though qualification level differs.
What is the thermal resistance (θJA) of JL193BGA in still air?
JL193BGA has a junction-to-ambient thermal resistance (θJA) of 174°C/W under still-air conditions, as specified in the Absolute Maximum Ratings section. This value reflects the TO-99 metal can package's thermal performance and must be used for derating calculations at elevated ambient temperatures.
Can JL193BGA operate with a single 5 V supply?
Yes, JL193BGA is explicitly rated for single-supply operation from 5.0 VDC to 36 VDC. Its input common-mode range includes ground, and output logic levels remain compatible with TTL/CMOS at 5 V - verified in the "Wide Supply Voltage Range" and "Input Common-Mode Voltage Range Includes Ground" features.
