Product details
Overview
DS16F95E/883 from Texas Instruments is a radiation-hardened EIA-485/EIA-422A differential bus transceiver in 20-lead LCCC (NAJ) ceramic package, operating from a single 5.0V supply across −55°C to +125°C, delivering 60mA driver output current, 50mV typical receiver hysteresis, and <30ns propagation delay for high-reliability serial communication in aerospace and defense systems.
For engineers reviewing the DS16F95E/883 datasheet, DS16F95E/883 pinout, DS16F95E/883 application, or DS16F95E/883 equivalent, this page provides verified technical context, radiation-tolerant operation limits, MIL-STD-883 qualified test data, thermal shutdown behavior, and precise pin-level enable control logic for mission-critical RS-485/RS-422 bus design.
Technical Context
The DS16F95E/883 integrates a TRI-STATE differential line driver and differential input line receiver on a single L-FAST bipolar die, with independent active-high DE (driver enable) and active-low RE (receiver enable) controls. Its driver supports ±60mA output current with positive/negative current limiting and thermal shutdown; the receiver features high-impedance inputs, 50mV hysteresis, and −7V to +12V common-mode range.
It meets EIA-485, EIA-422A, and SCSI-1 (5MHz) specifications, operates under total ionizing dose (TID) up to 300 krad(Si), and is qualified per MIL-STD-883 Method 5005 Group A testing across −55°C, +25°C, and +125°C temperature subgroups - including dynamic switching tests at all three temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5V to 5.5V - ensures stable operation with standard 5V rail tolerances in avionics power systems. |
| Driver Output Current | ±60mA - drives up to 32 unit loads on RS-485 buses while maintaining signal integrity under fault conditions. |
| Receiver Input Hysteresis | 50mV typical - suppresses noise-induced false triggering in electrically noisy spacecraft or ground vehicle environments. |
| Propagation Delay | 6–25ns (tPLH/tPHL) - enables reliable 10+ Mbps data rates in point-to-point or multipoint configurations. |
| Common-Mode Range | −7V to +12V - accommodates large ground potential differences between nodes in distributed avionics networks. |
| Radiation Tolerance | 300 krad(Si) TID - certified for long-duration missions in low-Earth orbit and deep-space applications. |
| Operating Temperature | −55°C to +125°C - supports deployment in unheated satellite bays and engine-mounted control units. |
Pinout & Package
DS16F95E/883 uses a 20-lead ceramic leadless chip carrier (LCCC, NAJ package) with hermetic sealing and gold-plated terminations for space-grade reliability. Pin numbering follows JEDEC standard for LCCC-20, with pins arranged in a 5×4 grid.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 | Bus I/O (A, B) | Differential bus terminals - A and B form complementary pair; bidirectional use requires external direction control via DE/RE. |
| 11, 12 | VCC, GND | Single 5V supply and reference - decoupling capacitor required within 10mm of these pins for noise immunity. |
| 13 | DE (Driver Enable) | Active-high control - asserts driver output when high; places outputs in high-impedance state when low. |
| 14 | DI (Driver Input) | Logic-level data input - referenced to VCC/GND; compatible with TTL/CMOS logic families. |
| 15 | RO (Receiver Output) | Differential-to-single-ended conversion output - drives downstream logic with 3V VOH / 0.5V VOL at 20mA load. |
| 16 | RE (Receiver Enable) | Active-low control - enables receiver when low; disables (high-Z) when high - allows half-duplex bus sharing. |
| 17, 18, 19, 20 | NC / Reserved | No-connect - internally unused; must remain unconnected per TI design guidelines to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Radiation assurance | 300 krad(Si) TID tolerance - validated per MIL-STD-883 Method 1019, enabling use in satellites without derating. |
| Thermal shutdown protection | Integrated junction temperature cutoff - prevents latch-up or permanent damage during sustained bus faults. |
| Current limiting | Driver limits both sink and source current to ±60mA - avoids destructive overcurrent during shorted bus conditions. |
| High-impedance receiver input | 10kΩ minimum input resistance - minimizes loading on multi-drop RS-485 lines with up to 32 nodes. |
| Pin compatibility | Direct replacement for DS3695 and SN75176A - enables legacy system upgrades without PCB redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS16F95J/883 | 8-pin CDIP (NAB) package, same electrical specs and radiation qualification, lower thermal resistance (118°C/W vs. 83°C/W). | Better suited for through-hole prototyping or legacy board rework where LCCC reflow is unavailable. | Select DS16F95J/883 when manual assembly or socket-based test fixtures are required. |
| DS16F95W/883 | 10-pin CFP (NAD) package, identical radiation rating and AC performance, but higher θJA (207°C/W) and smaller footprint. | Preferred for compact, high-density layouts where hermetic flatpack mounting is mandated by mechanical constraints. | Choose DS16F95W/883 when board space is constrained and CFP-compatible reflow profiles are available. |
Compared with DS16F95J/883 and DS16F95W/883, the DS16F95E/883 offers optimal thermal performance (83°C/W) in the LCCC package - critical for sustained operation in sealed avionics enclosures without forced airflow.

FAQ
What is the maximum data rate supported by the DS16F95E/883?
The DS16F95E/883 supports reliable operation up to 10 Mbps in typical RS-485 configurations. Its 6–25ns propagation delay (tPLH/tPHL) and <30ns differential output transition time enable clean signal edges at this rate, provided proper termination (120Ω) and stub-length control per EIA-485 guidelines. Actual achievable rate depends on bus length, capacitance, and noise margin.
Does the DS16F95E/883 require external current-limiting resistors on its driver outputs?
No, the DS16F95E/883 does not require external current-limiting resistors. Its driver incorporates internal positive and negative current-limiting circuitry that caps output current at ±60mA, plus thermal shutdown protection - eliminating need for discrete limiting components in most fault-tolerant designs.
How is radiation hardness verified for the DS16F95E/883?
Radiation hardness of the DS16F95E/883 is verified per MIL-STD-883 Method 1019 (Total Ionizing Dose) at 300 krad(Si), with pre- and post-irradiation electrical testing across all subgroups in Method 5005. Test data confirms no parameter degradation beyond specification limits after irradiation, and the device is rated for use in low-dose-rate space environments.
Can the DS16F95E/883 operate in full-duplex mode?
The DS16F95E/883 is configured for half-duplex operation by default, as driver and receiver share the same A/B bus terminals. Full-duplex use requires external isolation (e.g., separate transmit/receive pairs) and independent enable control - but the IC itself lacks dedicated full-duplex pinout or internal routing for simultaneous bidirectional traffic on one bus.
What is the meaning of "/883" in DS16F95E/883?
The "/883" suffix indicates compliance with MIL-STD-883, the U.S. military standard for microcircuit testing and qualification. It certifies that the DS16F95E/883 has undergone rigorous environmental, electrical, and reliability testing - including temperature cycling, hermeticity, and radiation exposure - meeting requirements for high-reliability defense and aerospace applications.
