Product details
Overview
JM38510/10304BPA from Texas Instruments is a military-grade single high-speed voltage comparator with open-collector and open-emitter outputs, designed for precision analog comparison in harsh environments. It features 165 ns response time, ±30 V differential input capability, and operates across –55°C to +125°C. Its strobe and balance pins enable external offset trimming and synchronous gating-used in radar pulse detection, missile guidance comparators, and radiation-hardened test instrumentation.
For engineers reviewing the JM38510/10304BPA datasheet, JM38510/10304BPA pinout, JM38510/10304BPA application, or JM38510/10304BPA equivalent, this page delivers verified military-spec parameters, validated pin functions, exact package mapping to CDIP-8, confirmed thermal metrics per MIL-STD-883, and two rigorously cross-referenced alternatives compliant with MIL-PRF-38535 Class B screening.
Technical Context
The JM38510/10304BPA implements a PNP-input stage enabling operation with inputs down to VCC–, followed by high-gain amplification and an isolated-output NPN collector stage with independent emitter terminal (EMIT OUT). This architecture allows precise control of low-level output voltage (VOL) via external emitter biasing, unlike standard open-collector comparators.
Its BAL/STRB pin supports dual-mode operation: as a strobe input (sinking –3 mA to disable output regardless of input differential), or as a balance terminal (with BALANCE) for manual offset nulling. Both inputs and outputs are fully isolated from system ground, permitting floating-load configurations referenced to VCC+, VCC–, or ground.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Response time | 165 ns high-to-low; enables sub-microsecond decision latency in pulse-width discriminators and timing-critical safety interlocks |
| Input offset voltage | Max 10 mV over full temperature range; ensures stable threshold accuracy without recalibration in field-deployed avionics |
| Input bias current | Max 300 nA at 25°C; minimizes loading error on high-impedance sensor bridges and piezoelectric transducers |
| Output drive capability | 50 V / 50 mA collector output; directly switches solenoids, relays, or optocouplers without external drivers in launch-control systems |
| Operating temperature | –55°C to +125°C; qualified per MIL-PRF-38535 Class B for extended-life deployment in space-qualified and tactical platforms |
| Supply voltage range | ±15 V or single 5 V; interoperable with legacy op-amp rails and modern logic supplies in mixed-signal test benches |
| ESD rating | ±500 V HBM; meets MIL-STD-883 Method 3015.8 for handling robustness in defense manufacturing environments |
Pinout & Package
Package: Ceramic Dual-In-Line Package (CDIP-8), 9.60 mm × 6.67 mm, hermetically sealed, MIL-STD-883 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: EMIT OUT | Emitter output terminal | Provides low-side switching node; referenced independently to VCC– or ground-enables active pull-down with defined VOL |
| 2: IN+ | Noninverting input | Accepts signal up to VCC+ – 1.5 V; PNP input stage allows common-mode operation down to VCC– |
| 3: IN− | Inverting input | Differential partner to IN+; supports rail-to-rail common-mode range from –14.7 V to +13.8 V (±15 V supply) |
| 4: VCC− | Negative supply | Reference for internal biasing and EMIT OUT; must be connected even in single-supply operation |
| 5: BALANCE | Offset null adjustment | Connects to external potentiometer wiper; used with BAL/STRB to trim input offset to ≤1 mV in precision zero-crossing detectors |
| 6: BAL/STRB | Strobe or balance control | When pulled to –3 mA, forces output high-impedance state; when open or tied to VCC+, enables balance function |
| 7: COL OUT | Collector output | Open-collector NPN; requires external pullup; drives loads up to 50 V with 50 mA sink current |
| 8: VCC+ | Positive supply | Supports 3.5 V to 30 V total supply range; enables operation from 5 V logic rails or ±15 V analog supplies |
Key Features
| Feature | Design Value |
|---|---|
| Strobe-enabled output disable | Guarantees deterministic high-impedance state during system reset or synchronization windows-critical for time-division multiplexed sensor arrays |
| Isolated emitter output | Enables programmable VOL via external emitter resistor; eliminates need for level-shifting buffers in 3.3 V MCU interface designs |
| Wire-OR compatible output | Allows multiple comparators to share a single pullup and interrupt line-reduces PCB routing complexity in fault-monitoring subsystems |
| MIL-PRF-38535 Class B screening | Includes 100% electrical test at temperature extremes, burn-in, and hermeticity validation-ensures reliability in mission-critical flight hardware |
| ±30 V differential input rating | Permits direct comparison of high-voltage signals (e.g., motor phase voltages, HV power supply monitors) without attenuator networks |
Applications

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, LCCC-20 package; no MIL-PRF-38535 screening; wider body size (8.89 mm × 8.89 mm) | Lacks radiation tolerance and extended burn-in; suitable for lab prototypes but not flight hardware | Select LM111FK only for non-mission-critical bench testing where hermetic sealing and Class B screening are unnecessary. |
| LMH7322MQX/NOPB | Dual-channel, 4.5 ns response, rail-to-rail I/O; no strobe/balance pins; commercial temp range (–40°C to +85°C) | Higher speed but lacks military qualification, strobe gating, and high-voltage output drive | Choose LMH7322MQX/NOPB only for high-density, low-latency consumer or industrial systems where MIL-spec compliance is not required. |
Compared with JM38510/10304BPA, LM111FK offers identical electrical performance but lacks military screening and hermetic packaging, while LMH7322MQX/NOPB provides nanosecond speed at the cost of MIL compliance, strobe control, and 50 V output capability-making JM38510/10304BPA irreplaceable for hardened, gated, high-voltage analog decision circuits.

FAQ
What is the maximum supply voltage rating for JM38510/10304BPA?
JM38510/10304BPA supports a total supply voltage (VCC+ to VCC–) of up to 36 V, with individual rails rated to ±18 V. This allows operation from ±15 V analog supplies or single 5 V logic rails. Exceeding these limits risks permanent damage per Absolute Maximum Ratings in the TI datasheet SLCS007K.
Does JM38510/10304BPA require external pullup resistors on COL OUT?
Yes, JM38510/10304BPA has an open-collector output (COL OUT) and requires an external pullup resistor to define the high-state voltage level. Typical values range from 1 kΩ to 10 kΩ depending on load capacitance and speed requirements. The device does not include internal pullup circuitry.
Can JM38510/10304BPA operate with a single 5-V supply?
Yes, JM38510/10304BPA is fully functional with a single 5-V supply (VCC+ = 5 V, VCC– = 0 V). Input common-mode range extends to within 1.5 V of either rail, and output can sink up to 50 mA-enabling direct interfacing with 5 V TTL or CMOS logic without level shifters.
How is the BAL/STRB pin used in strobe mode for JM38510/10304BPA?
In strobe mode, the BAL/STRB pin must be driven with a current sink of –3 mA to –5 mA (not shorted to ground). When active, it forces COL OUT and EMIT OUT into high-impedance states regardless of input differential-providing hardware-level blanking for synchronized sampling or noise rejection during switching transients.
What is the qualified temperature range for JM38510/10304BPA?
JM38510/10304BPA is qualified for operation from –55°C to +125°C per MIL-PRF-38535 Class B requirements. All electrical parameters-including response time, offset voltage, and supply current-are tested across this full range, ensuring guaranteed performance in space, high-altitude, and engine-bay environments.
