Product details
Overview
M38510/10403BEA from Texas Instruments is a military-grade dual differential line driver IC designed for high-reliability balanced transmission over twisted-pair lines. It features TTL-compatible totem-pole outputs with separate YP/YS and ZP/ZS terminals per channel, operates from a single 5-V supply, delivers ±40 mA output current, and is characterized for –55°C to 125°C operation in CDIP (J) package.
For engineers reviewing the M38510/10403BEA datasheet, M38510/10403BEA pinout, M38510/10403BEA application, or M38510/10403BEA equivalent, this device serves as a drop-in military-qualified replacement for SN55114J and DS9614 in ruggedized data bus and avionics serial interface designs requiring open-collector/open-emitter flexibility and short-circuit protection.
Technical Context
The M38510/10403BEA implements two independent differential drivers, each with triple-input AND/NAND logic and configurable output stages-supporting totem-pole, open-collector, or open-emitter configurations via external connection of YP–YS and ZP–ZS pins. Its internal structure includes clamp diodes at all inputs and outputs, enabling robust ESD tolerance and rail-to-rail signal handling.
Each channel accepts TTL-level inputs (VIH = 2 V, VIL = 0.8 V), produces VOH ≥ 2.4 V at –10 mA and VOL ≤ 0.4 V at 40 mA, and achieves propagation delays of 11–20 ns (tPHL/tPLH) under 30-pF load conditions. The device draws up to 50 mA total supply current (ICC) at VCC = 5.5 V and supports safe short-circuit operation up to 120 mA per output.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual differential line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN55114J | Identical electrical specs and pinout; same CDIP-16 package but non-QML (Class V) screening. | Lacks MIL-PRF-38535 Class B qualification and extended reliability testing required for flight-critical use. | Select SN55114J only for ground-test or non-flight prototype validation where full QML compliance is not mandated. |
| DS9614CN | Functionally identical architecture and pinout; rated for 0°C to 70°C only, SOIC-16 package, RoHS-compliant finish. | Not suitable for military temperature range or hermetic packaging requirements; limited to commercial industrial systems. | Choose DS9614CN for cost-sensitive, non-military embedded systems where extended temperature and radiation tolerance are unnecessary. |
Compared with SN55114J and DS9614CN, M38510/10403BEA uniquely combines full MIL-PRF-38535 Class B qualification, –55°C to 125°C operation, and hermetic CDIP packaging-making it the sole option for deployed flight hardware, missile guidance telemetry, and nuclear command-and-control infrastructure where zero field failures are mandatory.

FAQ
What is the qualified temperature range for M38510/10403BEA?
The M38510/10403BEA is fully characterized and qualified for continuous operation from –55°C to 125°C ambient temperature, per MIL-PRF-38535 Class B requirements. This range is validated through temperature cycling, steady-state burn-in, and parametric testing at extremes, ensuring reliability in jet engine bays, missile canisters, and satellite payload compartments where thermal stress is severe.
Is M38510/10403BEA pin-compatible with SN55114J?
Yes, M38510/10403BEA is pin-compatible with SN55114J - both use identical CDIP-16 (J) package footprints, pin numbering, and functional pin assignments. However, M38510/10403BEA undergoes additional MIL-PRF-38535 Class B screening including lot acceptance testing and extended environmental stress screening not applied to SN55114J.
Does M38510/10403BEA support open-collector output configuration?
Yes, M38510/10403BEA supports open-collector operation by leaving YP and ZP unconnected and using only YS and ZS as active-low outputs. This configuration is explicitly documented in the datasheet and enables wired-OR bus topologies, termination flexibility, and compatibility with legacy RS-422 receivers requiring negative logic drive.
What is the maximum short-circuit current rating for M38510/10403BEA outputs?
The M38510/10403BEA is rated for ±120 mA short-circuit output current per channel under recommended operating conditions. This value is specified in the "Short-circuit output current" parameter (IOS) and reflects sustained safe operation when one output is shorted to VCC or GND - critical for fault-tolerant bus architectures where line shorts may occur during deployment.
Can M38510/10403BEA be used as a TTL expander or phase splitter?
Yes, the M38510/10403BEA is explicitly designed for use as a TTL expander or phase splitter, as stated in its official datasheet. Its totem-pole outputs deliver TTL-compatible voltage levels (VOH ≥ 2.4 V, VOL ≤ 0.4 V) and high-current drive (±40 mA), allowing it to fan out to multiple downstream TTL loads or generate complementary signals for clock distribution and logic inversion tasks.
