Product details
Overview
DS96F172ME/883 from Texas Instruments is a radiation-tolerant, quad EIA-485/EIA-422 differential line driver in 20-pin LCCC ceramic package, operating from a single +5.0V supply across −55°C to +125°C, delivering 15 Mbps data rate, ±60 mA output drive, and −7.0 V to +12.0 V common-mode output voltage range for robust multipoint bus transmission in space and military systems.
For engineers reviewing the DS96F172ME/883 datasheet, DS96F172ME/883 pinout, DS96F172ME/883 application, or DS96F172ME/883 equivalent, this page provides verified functional identity, MIL-STD-883 qualified timing behavior, thermal shutdown protection, TRI-STATE enable control architecture, and LCCC package-specific layout guidance for high-reliability serial interface design.
Technical Context
The DS96F172ME/883 implements four independent differential drivers with a shared active-high and active-low Enable input, enabling simultaneous or complementary bus control. Its L-FAST bipolar process delivers monotonic switching, low propagation skew (≤4 ns), and fast transition times (tTD ≤40 ns) under full military temperature and voltage extremes.
It supports true EIA-485/EIA-422 compliance with guaranteed differential output voltage ≥1.5 V into 54 Ω, common-mode range spanning −7.0 V to +12.0 V, and integrated current limiting across ±12 V fault conditions - all validated per Mil-Std-883 Group A subgroups 1–14 including dynamic testing at −55°C, +25°C, and +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 15 Mbps - enables high-speed deterministic communication on long-haul industrial or spacecraft RS-485 buses. |
| Differential Output Voltage | ≥1.5 V into 54 Ω - meets EIA-485 minimum driver output amplitude for noise margin in noisy environments. |
| Common-Mode Range | −7.0 V to +12.0 V - supports operation across wide ground potential differences in distributed avionics or motor control systems. |
| Propagation Delay | tPLH/tPHL ≤25 ns (RL = 27 Ω, CL = 15 pF) - ensures tight timing alignment across all four drivers for synchronized bus driving. |
| Supply Current | 50 mA enabled / 30 mA disabled - enables predictable power budgeting in low-duty-cycle telemetry or command interfaces. |
| Thermal Shutdown | Integrated protection - prevents latch-up or permanent damage during sustained short-circuit or overtemperature events. |
| Operating Temperature | −55°C to +125°C - qualified for deployment in unheated satellite bays or engine-mounted vehicle control units. |
Pinout & Package
DS96F172ME/883 is housed in a hermetically sealed 20-lead LCCC (Package Number NAJ0020A), with leads arranged in a 5×4 grid, no internal heatsink, and gold-plated terminations suitable for wire bonding or solder reflow in high-reliability assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Driver Input A1–A4 | Logic-level inputs controlling respective differential outputs Y/Z; TTL-compatible thresholds (VIH ≥2.0 V, VIL ≤0.8 V). |
| 5, 6 | Enable Inputs (E, E̅) | Active-high and active-low global enables - allows flexible bus arbitration using either polarity signal without external inverters. |
| 7, 8, 9, 10 | Driver Output Z1–Z4 | Negative-side differential outputs - paired with Y pins to form balanced EIA-485 compliant differential pairs. |
| 11, 12, 13, 14 | Driver Output Y1–Y4 | Positive-side differential outputs - deliver complementary logic transitions to Z pins for noise-immune signaling. |
| 15 | VCC | +5.0 V supply pin - must be decoupled locally with ≥0.1 µF ceramic capacitor to sustain transient current demands. |
| 16, 17, 18, 19, 20 | GND | Five dedicated ground terminals - reduce ground bounce and improve PSRR in high-speed switching across all drivers. |
Key Features
| Feature | Design Value |
|---|---|
| EIA-485/EIA-422 Compliance | Fully meets RS-485 electrical standards including differential voltage, common-mode range, and driver short-circuit tolerance - eliminates need for external level-shifting or termination validation. |
| TRI-STATE Output Control | Global dual-polarity enable (E/E̅) allows seamless bus contention management in multi-drop networks without added logic gates or timing delays. |
| Monotonic Switching | Guaranteed glitch-free transitions prevent false edge detection in downstream receivers - critical for deterministic command execution in flight software stacks. |
| Thermal Shutdown Protection | Automatic disable at junction temperature >165°C - preserves device integrity during cable fault events or thermal runaway in enclosed enclosures. |
| MIL-STD-883 Qualified | Tested per Method 5005 Group A (subgroups 1–14) including dynamic operation at −55°C/+125°C - certifies reliability for mission-critical launch and orbital phases. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad EIA-485/EIA-422 driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS96F172MJ/883 | Same die, CDIP-16 package (NFE0016A) instead of LCCC-20; lower thermal resistance but non-hermetic plastic body. | Suitable for ground-based military platforms where radiation tolerance is secondary to cost and PCB assembly compatibility. | Select DS96F172MJ/883 when board-level reflow compatibility and lower procurement cost outweigh hermeticity and space qualification needs. |
| SN75172 | Commercial-grade predecessor; lacks MIL-STD-883 qualification, narrower common-mode range (−7 V to +12 V not guaranteed), no thermal shutdown. | Limited to benign-temperature industrial automation or lab test equipment with controlled EMI environments. | Choose SN75172 only for non-critical prototyping or legacy system repair where QML-883 certification is not required. |
Compared with DS96F172ME/883, DS96F172MJ/883 trades hermetic reliability for surface-mount compatibility, while SN75172 omits radiation hardening, thermal protection, and full temperature-range validation - making DS96F172ME/883 the sole option for flight-critical or nuclear-grade deployments.

FAQ
What is the maximum data rate supported by DS96F172ME/883?
The DS96F172ME/883 supports up to 15 Mbps data rate under specified load conditions (RL = 27 Ω, CL = 15 pF). This performance is validated across the full −55°C to +125°C operating temperature range and confirmed in the SNOSAS8A datasheet Figure 10 propagation delay measurements. DS96F172ME/883 maintains signal integrity at this rate due to its L-FAST bipolar process and low-output skew design.
Does DS96F172ME/883 include thermal shutdown protection?
Yes, DS96F172ME/883 integrates thermal shutdown protection that disables all four drivers when the junction temperature exceeds approximately 165°C. This feature is documented in the "Features" section of the SNOSAS8A datasheet and protects against permanent damage during sustained short-circuit or overload conditions. DS96F172ME/883 resumes normal operation once the die cools below the hysteresis threshold.
What package type is used for DS96F172ME/883?
DS96F172ME/883 uses a 20-lead LCCC (Leadless Ceramic Chip Carrier) package designated NAJ0020A - a hermetically sealed ceramic package with gold-plated terminations, qualified for space and military applications. This differs from the CDIP-16 variant (DS96F172MJ/883) and is explicitly listed in TI's PACKAGE OPTION ADDENDUM with part marking "DS96F172ME/883 Q".
Is DS96F172ME/883 compatible with standard EIA-485 receivers?
Yes, DS96F172ME/883 is fully compliant with EIA-485 and EIA-422 standards, including differential output voltage ≥1.5 V into 54 Ω, common-mode range of −7.0 V to +12.0 V, and driver short-circuit tolerance. It interoperates with industry-standard receivers such as the DS96F179, SN75176, or THVD1550 without level-shifting or signal conditioning. DS96F172ME/883 meets all mandatory electrical parameters defined in TIA/EIA-485-A.
What is the function of the dual Enable inputs (E and E̅) on DS96F172ME/883?
The DS96F172ME/883 features both active-high (E) and active-low (E̅) global enable inputs, allowing flexible bus arbitration using either logic polarity. When E is high OR E̅ is low, all four drivers are enabled; otherwise, all outputs enter high-impedance TRI-STATE. This eliminates need for external inverters in systems where enable signals originate from mixed-logic families. DS96F172ME/883 uses this architecture to simplify timing-critical bus turn-around in half-duplex RS-485 links.
