Product details
Overview
M38510/10304BGA from Texas Instruments is a military-grade voltage comparator with 200 nA max input current, ±30 V differential input range, and 200 ns typical response time. It operates from single 5V to dual ±15V supplies, features strobe capability and offset null pins, and drives TTL/DTL/RTL loads or relays up to 50 mA - used in precision zero-crossing detection and relay control in aerospace power monitoring systems.
For engineers reviewing the M38510/10304BGA datasheet, M38510/10304BGA pinout, M38510/10304BGA application, or M38510/10304BGA equivalent, this page delivers verified military-spec electrical parameters, TO-99 package layout, strobe-enabled isolation architecture, and direct alternatives for high-reliability analog signal conditioning in extended-temperature environments.
Technical Context
The M38510/10304BGA implements an open-collector NPN output stage compatible with ground-, positive-, or negative-referenced loads, enabling flexible interface topologies including wired-OR logic and relay driving. Its input stage uses matched transistor pairs with trimmable offset via external potentiometer across pins 5 and 6.
Strobe functionality (pin 7) allows dynamic disabling of both input and output stages, reducing input current to 50 pA when active - critical for low-power wake-up circuits. The device meets MIL-STD-883 Group A testing per subgroups 1–11, covering static/dynamic/functional tests across –55°C to +125°C.

Pinout & Package
Package: TO-99 metal can (LMC0008C), hermetically sealed, 8-pin circular layout with case connected to pin 4. Designed for high-reliability mounting on ceramic substrates with thermal pad grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output Collector | Open-collector NPN output - requires external pull-up; sinks up to 50 mA to drive relays or logic. |
| 2 | Inverting Input (–) | Differential input node - referenced to internal matched pair; accepts ±30 V differential swing. |
| 3 | Non-Inverting Input (+) | Differential input node - identical voltage range and bias current as pin 2. |
| 4 | Case / Ground Reference | Internally connected to metal can - must be tied to system ground or negative supply for shielding. |
| 5 | Offset Null (–) | Connects to emitter of input stage PNP - used with external potentiometer to null offset voltage. |
| 6 | Offset Null (+) | Connects to emitter of input stage NPN - forms balanced null network with pin 5. |
| 7 | Strobe Input | Active-low enable - pulling current disables both input and output stages, reducing input current to 50 pA. |
| 8 | Positive Supply (V+) | Connects to +VCC rail - supports single 5 V or dual ±15 V operation; decoupling required within 2 inches. |
Key Features
| Feature | Design Value |

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 package; no MIL-STD-883 screening; rated –25°C to +85°C. | Lacks Group A testing and extended temperature range - unsuitable for flight-critical or downhole use. | Select LM111H only for lab prototypes or non-mission-critical ground equipment where cost outweighs reliability. |
| LM311J | Same functional architecture but plastic DIP-8 package; lower thermal resistance (θJA = 100°C/W); RoHS-compliant finish. | Not hermetically sealed; unqualified for >105°C ambient; lacks strobe pin and case grounding. | Choose LM311J for cost-sensitive industrial controls where extended temperature and hermeticity are not required. |
Compared with LM111H and LM311J, the M38510/10304BGA uniquely combines military screening, TO-99 hermetic packaging, strobe capability, and –55°C to +125°C operation - making it irreplaceable in safety-critical analog front-ends where failure modes must be eliminated, not mitigated.

FAQ
What is the maximum differential input voltage rating for M38510/10304BGA?
The M38510/10304BGA supports a differential input voltage range of ±30 V, as specified in the Absolute Maximum Ratings table. This allows direct interfacing with high-voltage sensors or transformer-coupled signals without external attenuation. Exceeding ±30 V risks permanent damage to the input stage, regardless of common-mode level. The rating applies across the full –55°C to +125°C operating range and is validated per MIL-STD-883 Method 5005.
Does M38510/10304BGA support single-supply operation?
Yes, the M38510/10304BGA operates from a single 5 V supply, as confirmed in the Features and Recommended Operating Conditions sections. When using single-supply configuration, the negative supply pin (pin 4, case) must be connected to circuit ground, and the non-inverting input (pin 3) is typically biased above ground to establish a valid comparison threshold. Input common-mode range extends to within 1.5 V of ground under this condition.
How is the strobe function implemented on M38510/10304BGA?
The strobe function is controlled by pin 7 (Strobe Input), which acts as an active-low enable. Pulling pin 7 low (≤0.8 V) disables both input and output stages, reducing input current to 50 pA and forcing the output into high-impedance state. The strobe pin must never be grounded directly - instead, it requires current-limited sourcing (max 10 mA) from a logic driver. This feature is used in synchronized sampling systems to eliminate comparator noise during acquisition windows.
What package type does M38510/10304BGA use, and is it hermetically sealed?
M38510/10304BGA uses the TO-99 metal can package (designator LMC0008C), which is hermetically sealed per MIL-STD-883 requirements. The case (pin 4) serves as both mechanical shield and thermal path, and must be soldered to a grounded copper area on the PCB. This construction provides immunity to moisture ingress, outgassing, and ionizing radiation - essential for space-qualified and downhole applications.
Can M38510/10304BGA outputs be wire-OR'ed, and what design precautions apply?
Yes, M38510/10304BGA outputs support wired-OR logic due to its open-collector architecture. To implement this, connect all collector outputs (pin 1) to a shared pull-up resistor tied to the appropriate logic rail. Ensure each device shares identical supply references and that total sink current remains below 50 mA per output. Avoid mixing M38510/10304BGA with non-strobe-compatible comparators on the same bus, as timing mismatches may cause metastability.
