Product details
Overview
JM38510/11201BCA from Texas Instruments is a military-grade quad differential comparator IC designed for precision voltage comparison in harsh environments. It operates from single supplies (2 V to 30 V) or dual supplies (±1 V to ±15 V), features open-collector outputs compatible with TTL/MOS/CMOS, and delivers 2 mV typical input offset voltage, 25 nA typical input bias current, and −55°C to +125°C operating range - enabling use in power supervision, oscillator circuits, and industrial control systems.
For engineers reviewing the JM38510/11201BCA datasheet, JM38510/11201BCA pinout, JM38510/11201BCA application, or JM38510/11201BCA equivalent, this page provides verified technical context, military-qualified package details (CDIP-14), key electrical specifications, functional pin mapping, real-world application scenarios, and validated alternative options for high-reliability design-in.
Technical Context
The JM38510/11201BCA implements four independent comparators with PNP Darlington-pair inputs, enabling rail-to-rail common-mode input operation down to ground and up to VCC − 1.5 V at 25°C (VCC − 2 V over full temperature range). Its open-collector NPN output stage supports wired-AND logic and level translation across mixed-voltage domains.
Designed per MIL-PRF-38535 Class B requirements, all parameters are 100% tested across −55°C to +125°C. Input differential voltage tolerance reaches ±36 V, supply current remains stable at 0.8 mA (typ) regardless of supply voltage, and response time is 1.3 µs (typ) with 100-mV overdrive into 5.1 kΩ pull-up and 15 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | Single: 2 V to 30 V; Dual: ±1 V to ±15 V - supports wide-input industrial and avionics power rails without external regulation. |
| Input Offset Voltage | 2 mV (typ), 9 mV (max, −55°C to +125°C) - enables accurate threshold detection in precision monitoring applications. |
| Input Bias Current | 25 nA (typ), 300 nA (max, −55°C to +125°C) - minimizes loading on high-impedance sensor or reference networks. |
| Common-Mode Range | 0 V to VCC − 2 V - allows direct interfacing with ground-referenced signals and rail-sensing topologies. |
| Output Type | Open-collector NPN - permits flexible logic-level translation, wired-AND bus configuration, and external pull-up selection. |
| Response Time | 1.3 µs (typ, 100-mV overdrive) - suitable for fast edge-detection in pulse-width modulation and fault-monitoring circuits. |
| Operating Temperature | −55°C to +125°C - qualified for deployment in military, aerospace, and under-hood automotive environments. |

| 14 | Comparator 3 Output | Open-collector NPN drain - routed separately for discrete logic or analog feedback paths. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Power Supervision | Oscillator Circuits |
|---|---|
Use Scenario: Monitoring multiple DC rails (e.g., 3.3 V, 5 V, 12 V) in avionics subsystems for undervoltage/overvoltage faults. IC Role / Device Role: Quad comparator configured as independent voltage window detectors with hysteresis via external resistors.

| Industrial Control Logic | Automotive Body Control |
Use Scenario: Converting analog sensor outputs (e.g., temperature, pressure) into digital status flags for PLC I/O modules operating in factory-floor environments. IC Role / Device Role: Comparator array performing threshold comparisons against precision references; outputs drive optocouplers or isolation buffers. Use Value: −55°C to +125°C operation and 0.8 mA supply current allow direct mounting near heat-generating equipment without derating. |
Use Scenario: Detecting door-open, seat-belt, or hood-latch states in body control modules using resistive divider networks tied to vehicle battery. IC Role / Device Role: Four-channel voltage comparator interpreting switch closure as voltage drop across pull-up network.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM139JB | Same die, commercial-grade CDIP-14; not MIL-PRF-38535 qualified; tested only over 0°C to +70°C. | Lacks full military temperature screening and 100% parametric test coverage; unsuitable for flight or defense programs. | Select LM139JB only for cost-sensitive, non-mission-critical industrial prototypes where extended temperature validation is unnecessary. |
| LM139FKB | LCCC-20 ceramic package; identical electrical specs; different pinout and footprint; higher thermal resistance (RθJA = 82.5°C/W). | Requires PCB redesign; better suited for high-density, low-profile layouts where CDIP height is prohibitive. | Choose LM139FKB when board space constraints preclude CDIP-14, and when LCCC's superior mechanical robustness justifies layout change. |
Compared with LM139JB, JM38510/11201BCA guarantees full military temperature performance and test coverage; compared with LM139FKB, it offers plug-compatible CDIP-14 mounting with lower thermal resistance and legacy compatibility in existing mil-spec designs.

FAQ
What is the operating temperature range of the JM38510/11201BCA?
The JM38510/11201BCA is fully characterized and tested over −55°C to +125°C, meeting MIL-PRF-38535 Class B requirements. This range is guaranteed for all electrical parameters, including input offset voltage, supply current, and response time - making JM38510/11201BCA suitable for deployment in engine compartments, avionics bays, and outdoor military enclosures without thermal derating.
Does the JM38510/11201BCA support dual-supply operation?
Yes, the JM38510/11201BCA supports dual-supply operation with ±1 V to ±15 V ratings (tested), provided the total supply differential remains between 2 V and 36 V and VCC is at least 1.5 V more positive than the input common-mode voltage. This capability enables bipolar signal conditioning in instrumentation and test equipment while retaining the same pinout and functionality as single-supply use.
What is the maximum differential input voltage the JM38510/11201BCA can withstand?
The JM38510/11201BCA has an absolute maximum differential input voltage rating of ±36 V, meaning the voltage difference between any IN+ and its corresponding IN− pin may reach 36 V in either polarity without damage. This specification is critical for applications involving inductive kickback, relay contact bounce, or unregulated sensor inputs where transient overvoltage is expected.
How does the open-collector output of the JM38510/11201BCA function in practice?
The JM38510/11201BCA features four independent open-collector NPN outputs that sink current when active (IN− > IN+ + VIO) and present high impedance when inactive. Each output requires an external pull-up resistor to define logic-high voltage level - enabling interoperability with 3.3 V, 5 V, or 12 V logic families and supporting wired-AND configurations for fault-bus signaling without additional logic gates.
Is the JM38510/11201BCA RoHS compliant?
No, the JM38510/11201BCA uses SNPB (tin-lead) lead finish and is explicitly marked "No" for RoHS compliance in TI's official packaging addendum. It is manufactured for legacy military and aerospace programs where leaded finishes are mandated for solder joint reliability under thermal cycling and mechanical shock - and is not intended for consumer or RoHS-restricted commercial applications.
