Overview
M38510/11201BCA from Texas Instruments is a quad differential voltage comparator designed for military-grade applications, operating from single supplies (2 V to 30 V) or dual supplies (±1 V to ±15 V), with 2 mV typical input offset voltage, 25 nA typical input bias current, and −55°C to +125°C operating temperature range - deployed in power supervision, oscillator timing, and industrial control systems.
For engineers reviewing the M38510/11201BCA datasheet, M38510/11201BCA pinout, M38510/11201BCA application, or M38510/11201BCA equivalent, this device delivers open-collector outputs compatible with TTL/MOS/CMOS logic, wide common-mode input range including ground, and tested compliance to MIL-PRF-38535 requirements for high-reliability embedded systems.
Technical Context
The M38510/11201BCA implements four independent comparators using PNP Darlington-pair inputs for low bias current and high gain, enabling accurate operation down to ground-level common-mode voltage. Its open-collector NPN output stage supports wired-AND configurations and external pull-up flexibility across logic families.
It is characterized over the full military temperature range (−55°C to +125°C) with all parameters tested per MIL-PRF-38535, featuring differential input voltage tolerance up to ±36 V and supply-current independence from VCC - critical for stable performance in harsh-environment analog monitoring circuits.

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 CDIP-14 package, identical electrical specs, but commercial-temp grade (0°C to +70°C) and non-MIL-qualified. | Lacks full −55°C to +125°C characterization and MIL-PRF-38535 testing - unsuitable for flight-critical or extended-temperature deployments. | Select LM139JB only for cost-sensitive, non-military prototypes or lab equipment where environmental stress is minimal. |
| LM339AW | CFP-14 package, same quad comparator function, but rated for −40°C to +85°C and not MIL-qualified; uses different die process. | Lower temperature range and absence of MIL-PRF-38535 validation limit use in defense/aerospace programs requiring traceable qualification data. | Choose LM339AW for commercial automotive or industrial control where CFP packaging and RoHS compliance are prioritized over military spec compliance. |
Compared with LM139JB and LM339AW, M38510/11201BCA uniquely provides full MIL-PRF-38535 qualification, guaranteed −55°C to +125°C operation, and tested parameter coverage - making it the sole option for systems requiring documented reliability under sustained thermal, shock, and radiation stress.

FAQ
What is the absolute maximum supply voltage rating for M38510/11201BCA?
The absolute maximum supply voltage for M38510/11201BCA is 36 V, as specified in the Absolute Maximum Ratings table. However, recommended operating conditions limit VCC to 30 V for reliable long-term operation. Exceeding 30 V may compromise parametric guarantees and lifetime reliability, even though the device survives short-term stress up to 36 V without immediate failure. Always refer to the TI SLCS160 datasheet for derating guidance.
Does M38510/11201BCA support dual-supply operation?
Yes, M38510/11201BCA supports dual-supply operation with ±1 V to ±15 V (tested) or ±1 V to ±18 V (absolute maximum). The supply difference must remain within 2 V to 36 V, and VCC must be at least 1.5 V more positive than the input common-mode voltage. This configuration enables bipolar signal comparison in analog front-ends used in test equipment and motor control feedback loops.
What is the meaning of "NC" pins on the M38510/11201BCA pinout?
"NC" stands for No Connect - these pins (e.g., pins 11, 12, 15, 17 in LCCC variant) have no internal connection to the die and must remain unconnected in PCB layout. On the CDIP-14 package of M38510/11201BCA, there are no NC pins; all 14 pins are functional. Confusion may arise from cross-referencing LCCC (FK) pin diagrams - always verify pin mapping against the J-package mechanical drawing for M38510/11201BCA.
Can M38510/11201BCA drive TTL logic directly?
Yes, M38510/11201BCA outputs are explicitly rated for TTL compatibility. Its open-collector NPN output can sink up to 20 mA and achieves VOL ≤ 400 mV at IOL = 4 mA (25°C), meeting TTL low-level input voltage requirements. When used with a 5 V pull-up resistor (e.g., 1–5 kΩ), M38510/11201BCA reliably interfaces with standard TTL gates, microcontrollers, and FPGAs without additional buffering.
Is M38510/11201BCA RoHS compliant?
No, M38510/11201BCA is not RoHS compliant. It uses SNPB (tin-lead) lead finish per its packaging data, and the "RoHS" column in TI's orderable addendum shows "No" for this part number. It is intended for military, aerospace, and legacy systems where leaded finishes are required for solder joint reliability under thermal cycling and mechanical shock - consistent with MIL-PRF-38535 Class K or S processing.
