Product details
Overview
M38510/10304BPA from Texas Instruments is a military-grade single high-speed voltage comparator with open-collector output, 165 ns response time, ±15 V dual-supply operation, and strobe-enabled disable functionality. It operates over –55°C to +125°C and drives loads up to 50 V at 50 mA - used in precision zero-crossing detection, relay control, and analog-to-digital interface circuits in aerospace and defense systems.
For engineers reviewing the M38510/10304BPA datasheet, M38510/10304BPA pinout, M38510/10304BPA application, or M38510/10304BPA equivalent, this page delivers verified electrical parameters, MIL-PRF-38535 qualification context, thermal metrics for LCCC-20 packaging, and real-world design guidance for strobe-controlled comparator deployment in safety-critical analog signal conditioning.
Technical Context
The M38510/10304BPA implements a PNP input stage enabling rail-to-rail common-mode input operation down to VCC−, followed by high-gain differential amplification and an isolated-emitter NPN open-collector output stage. Its BAL/STRB pin supports both external offset trimming and logic-controlled output disable.
Unlike standard comparators, it permits load referencing to ground, VCC+, or VCC−, and allows wire-OR connection of multiple outputs. All parameters are tested per MIL-PRF-38535 requirements, with full characterization across –55°C to +125°C including input bias current ≤300 nA and input offset voltage ≤10 mV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Response Time | 165 ns high-to-low (±15 V, 100-mV step, 5-mV overdrive) - enables sub-microsecond decision latency in timing-critical feedback loops |
| Supply Voltage Range | ±15 V (30 V total) - supports legacy op-amp rails and high-voltage industrial sensing without level-shifting |
| Output Drive Capability | 50 V / 50 mA collector sink - directly interfaces with relays, lamps, optocouplers, and TTL/MOS logic |
| Input Offset Voltage | Max 10 mV over full temperature range - ensures stable threshold accuracy in precision window detectors |
| Input Bias Current | Max 300 nA at 25°C - minimizes error in high-impedance sensor interfaces (e.g., photodiode, thermocouple) |
| Operating Temperature | –55°C to +125°C - qualified for extended-range military, avionics, and downhole electronics |
| Strobe Input Logic | Current-driven low-active (–3 mA to –5 mA) - provides deterministic output disable without floating pins or pullups |
Pinout & Package
LCCC-20 ceramic package (8.89 mm × 8.89 mm), hermetically sealed, leadless, surface-mountable with solder reflow compatibility. Designed for high-reliability board assembly under MIL-STD-883 conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 EMIT OUT | Emitter output terminal | Provides emitter-follower output referenced to VCC−; used for level-shifted logic or low-impedance sourcing |
| 2 IN+ | Noninverting input | Differential input node with PNP front-end; accepts signals down to VCC− −0.3 V |
| 3 IN− | Inverting input | Differential input node; common-mode range extends to VCC− −14.7 V (±15 V supply) |
| 4 VCC− | Negative supply rail | Reference for internal biasing and output stage; supports true dual-supply or single-supply (ground-referenced) operation |
| 5 BALANCE | Offset null adjustment | Two-terminal balance port for external 10-kΩ potentiometer to trim input offset voltage to <1 mV |
| 6 BAL/STRB | Strobe / balance select | Low-active strobe input (–3 mA) disables output; also serves as second balance terminal when used with BALANCE |
| 7 COL OUT | Collector output | Open-collector NPN output; sinks up to 50 mA; requires external pullup for logic-high assertion |
| 8 VCC+ | Positive supply rail | Primary power input; supports 3.5 V to 30 V total supply range (VCC+ − VCC−) |
| 10–19 NC | No internal connection | Unbonded pads; must remain unconnected per MIL-PRF-38535 mechanical and electrical integrity requirements |
| 20 VCC+ | Positive supply rail (redundant) | Second VCC+ bond pad for improved current distribution and reduced package inductance in high-speed switching |
Key Features
| Feature | Design Value |
|---|---|
| Strobe-enabled output disable | Guaranteed high-impedance state with –3 mA current drive on BAL/STRB - eliminates need for external enable logic or gate drivers |
| Rail-to-rail input common-mode range | Extends to VCC− −14.7 V and VCC+ −1.5 V - enables direct interfacing with sensors operating near supply rails |
| Isolated emitter output | EMIT OUT referenced independently to VCC− - allows level translation to negative logic domains or floating loads |
| Wire-OR output capability | Multiple COL OUT pins can be tied together with shared pullup - simplifies multi-threshold or priority encoder designs |
| MIL-PRF-38535 compliance | All parameters tested per Class B or S screening - includes burn-in, temperature cycling, and hermeticity validation for flight-critical use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM111FK | Same die, commercial LCCC-20 package; not MIL-PRF-38535 qualified; max temp +125°C but no screening or traceability | Lacks configuration control, lot traceability, and extended reliability testing - unsuitable for flight hardware or DoD procurement | Select LM111FK only for lab prototyping or non-critical ground systems where cost outweighs qualification rigor |
| LMH7322MF/NOPB | Modern 4.5 GHz gain-bandwidth amplifier with comparator mode; 1.8 ns propagation delay; 2.7–12 V single-supply only | Not dual-supply capable; no strobe or BALANCE pins; incompatible pinout and thermal profile; requires redesign | Choose LMH7322MF/NOPB only for new designs requiring nanosecond response and integrated hysteresis - not for drop-in replacement |
Compared with LM111FK and LMH7322MF/NOPB, M38510/10304BPA uniquely combines MIL-qualified reliability, dual-supply flexibility, strobe control, and legacy-compatible LCCC-20 packaging - making it irreplaceable for sustaining engineering of certified aerospace platforms.

FAQ
What is the qualified temperature range for M38510/10304BPA?
The M38510/10304BPA is fully characterized and qualified for operation from –55°C to +125°C per MIL-PRF-38535 Class B requirements. This includes parametric testing, burn-in, and thermal cycling across the full range - unlike commercial LM111 variants which specify narrower ranges or lack full-range validation.
Does M38510/10304BPA support single-supply operation?
Yes, M38510/10304BPA supports single-supply operation with VCC− grounded and VCC+ between 3.5 V and 30 V. The input common-mode range extends to within 1.5 V of VCC+ and down to VCC−, enabling direct interfacing with 0–5 V or 0–24 V sensor outputs without level-shifting circuitry.
How is the BAL/STRB pin used in M38510/10304BPA?
The BAL/STRB pin on M38510/10304BPA serves dual functions: when left open or tied to VCC+, it forms part of the offset null network with BALANCE; when driven with –3 mA to –5 mA current, it forces the COL OUT into high-impedance state regardless of input differential - enabling hardware-safe disable in fault conditions.
What is the maximum output current rating for M38510/10304BPA COL OUT?
The COL OUT pin of M38510/10304BPA is rated for continuous sink current up to 50 mA at VCE ≤ 1.5 V, with absolute maximum voltage of 50 V relative to VCC−. This allows direct driving of relays, LEDs, and optocouplers without external transistors - verified across –55°C to +125°C.
Is M38510/10304BPA pin-compatible with other LM111 variants?
M38510/10304BPA uses the LCCC-20 package and shares identical pinout with LM111FK, including NC pins and dual VCC+ connections. However, due to its MIL-PRF-38535 qualification, it is not interchangeable with commercial variants in production without requalification - even though physical layout matches.
