Product details
Overview
JM38510/10304BGA from Texas Instruments is a military-grade voltage comparator with 200 nA max input current, ±30 V differential input range, and 200 ns response time. It operates from single 5V to dual ±15V supplies, drives TTL/DTL/RTL/MOS loads, and supports strobe control and offset nulling. It is used in precision zero-crossing detection, relay drivers, and analog-to-digital interface circuits in aerospace and defense systems.
For engineers reviewing the JM38510/10304BGA datasheet, JM38510/10304BGA pinout, JM38510/10304BGA application, or JM38510/10304BGA equivalent, key selection considerations include its -55°C to +125°C operating range, TO-99 metal-can package with case-connected pin 4, strobe-enabled output disable, and compatibility with MIL-STD-883 Group A testing for high-reliability embedded timing and signal conditioning.
Technical Context
The JM38510/10304BGA implements an open-collector NPN output stage capable of sinking up to 50 mA at voltages up to 50 V relative to the negative supply. Its input stage uses a matched transistor pair with trimmable offset via pins 5 and 6, enabling precise nulling across temperature.
It features strobe capability (pin 7) that disables both input and output stages when pulled low, reducing input current to ~50 pA. The device maintains stable operation under wide supply conditions (5V single-ended to ±15V), with common-mode input range extending to ±30 V and CMRR ≥80 dB over -55°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | Single 5V to dual ±15V - supports logic-level and op-amp rail compatibility in mixed-signal systems. |
| Input Offset Voltage | ±3.0 mV max (−55°C to +125°C) - enables accurate threshold detection without external trimming in most applications. |
| Input Bias Current | 200 nA max over temperature - allows high-impedance sensor interfacing without significant loading error. |
| Response Time | 300 ns typical (5 mV overdrive, 50 pF load) - suitable for medium-speed digital conversion and pulse-width modulation feedback. |
| Differential Input Voltage | ±30 V - permits direct comparison of signals referenced to non-ground potentials, e.g., motor phase voltages. |
| Output Sink Current | 50 mA max - directly drives relays, lamps, or logic inputs without external buffer transistors. |
| Operating Temperature | −55°C to +125°C - qualified per MIL-STD-883 for deployment in avionics, missile guidance, and space-qualified electronics. |
Pinout & Package
Package: TO-99 metal can (package number LMC0008C), 8-pin, hermetically sealed, pin 4 internally connected to case for thermal and shielding integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output Collector | Open-collector NPN output; requires external pull-up to define logic high level and sink up to 50 mA. |
| 2 | Inverting Input (−) | Differential input node; accepts voltages from −30 V to +30 V relative to negative supply. |
| 3 | Non-Inverting Input (+) | Differential input node; same voltage range as pin 2; used for threshold or reference comparison. |
| 4 | Case / Ground Reference | Internally bonded to metal can; must be connected to system ground or shield plane for EMI suppression. |
| 5 | Offset Null (−) | Connects to one end of external 5 kΩ potentiometer for input offset voltage trimming. |
| 6 | Offset Null (+) | Connects to other end of same potentiometer; center wiper ties to negative supply for null adjustment. |
| 7 | Strobe Input | Active-low enable: pulling below 0.5 V disables both input and output stages, reducing quiescent current to ~50 pA. |
| 8 | Positive Supply (V+) | Accepts +5 V to +30 V in single-supply mode or +15 V in dual-supply configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Strobe-enabled shutdown | Reduces input current to ~50 pA and eliminates output leakage during idle periods, critical for low-power standby modes. |
| Offset voltage nulling | Adjusts input offset to ≤±0.5 mV via external potentiometer, enabling sub-millivolt threshold accuracy in precision sensing. |
| Wide common-mode range | ±30 V input voltage range allows direct comparison of signals floating above or below ground, e.g., motor phase or battery monitor rails. |
| Output stage isolation | Output can drive loads referenced to ground, positive supply, or negative supply - supports level-shifting and bidirectional switching. |
| MIL-STD-883 qualified | Group A testing per Method 5005 confirms reliability under extreme thermal cycling, vibration, and radiation environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM111H | Same die, commercial-grade TO-99 variant; lacks MIL-STD-883 screening and extended temperature validation. | Not approved for flight-critical or space-qualified use; limited to ground-based test equipment and non-safety systems. | Select LM111H only for cost-sensitive prototyping where full military qualification is unnecessary. |
| LM311J | Industrial-grade version with −25°C to +85°C rating; identical pinout but lower input bias current (150 nA typ) and no strobe function. | Suitable for commercial instrumentation but cannot replace JM38510/10304BGA in strobe-controlled or wide-temperature applications. | Choose LM311J for fixed-threshold detection in benign environments where strobe disable is not required. |
Compared with LM111H and LM311J, the JM38510/10304BGA uniquely combines military screening, strobe control, and guaranteed performance across −55°C to +125°C - making it irreplaceable in avionics health monitoring and radiation-hardened telemetry interfaces.

FAQ
What is the maximum allowable differential input voltage for JM38510/10304BGA?
The JM38510/10304BGA supports a differential input voltage range of ±30 V, meaning the voltage difference between pins 2 and 3 may not exceed 60 V peak-to-peak. This specification is absolute and applies across the full −55°C to +125°C operating range, enabling direct interface with high-voltage sensor outputs without external attenuation.
Does JM38510/10304BGA require external pull-up resistors on its output?
Yes, JM38510/10304BGA features an open-collector NPN output (pin 1) and requires an external pull-up resistor to define the logic-high voltage level. Typical values range from 1 kΩ to 10 kΩ depending on load capacitance and speed requirements; TI recommends 4.7 kΩ for general-purpose TTL interfacing with the JM38510/10304BGA.
How is the strobe function implemented on JM38510/10304BGA?
The strobe input (pin 7) of JM38510/10304BGA is active-low: pulling it below 0.5 V disables both input and output stages, reducing total supply current to ~50 pA. This feature allows precise timing control in pulsed measurement systems and eliminates false triggering during system initialization or fault recovery sequences involving the JM38510/10304BGA.
Can JM38510/10304BGA operate from a single 5V supply?
Yes, JM38510/10304BGA is fully specified for single 5V operation (V+ = 5V, V− = GND). In this configuration, the output swings from near ground to within ~0.4 V of V+, and the input common-mode range extends from 0 V to 3.5 V. All key parameters-including response time, offset voltage, and input current-are guaranteed under single-supply conditions for the JM38510/10304BGA.
What packaging and marking information identifies JM38510/10304BGA?
JM38510/10304BGA is supplied in a hermetically sealed TO-99 metal-can package (TI package number LMC0008C), with 8 leads and pin 4 internally connected to the case. The part is marked "JL111BGA" on the top surface, followed by date code and lot trace information; the full orderable number JM38510/10304BGA appears on the shipping label and certificate of conformance, not on the device body.
