Product details
Overview
DS96F175ME/883 from Texas Instruments is a radiation-tolerant, quad EIA-485/EIA-422 differential line receiver in 20-pin LCCC ceramic package, operating from single +5.0V supply with −7V to +12V common-mode input range, 15 Mbps data rate, and separate active-high enables per receiver pair - used in spacecraft telemetry downlink receivers and hardened avionics data buses.
For engineers reviewing the DS96F175ME/883 datasheet, DS96F175ME/883 pinout, DS96F175ME/883 application, or DS96F175ME/883 equivalent, key selection criteria include MIL-STD-883 Class B qualification, LCCC-20 hermetic packaging, ±200 mV input sensitivity over full common-mode range, TRI-STATE outputs, and compatibility with EIA-485 multipoint bus topologies in radiation-exposed environments.
Technical Context
The DS96F175ME/883 implements four independent differential receivers using TI's L-FAST bipolar technology, enabling high-speed operation up to 15 Mbps while maintaining low power consumption and robust noise immunity via 50 mV typical input hysteresis. Each receiver pair has dedicated active-high enable control, supporting selective channel activation in time-critical serial links.
It meets EIA-485, EIA-422A, and EIA-423A standards with guaranteed operation across −55°C to +125°C, ±25V absolute maximum input voltage tolerance, and high input impedance (>10 kΩ) for minimal bus loading - critical for long-haul, multi-drop RS-485 networks in space-grade systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 15 Mbps - supports high-throughput telemetry and command links without signal integrity degradation. |
| Common-Mode Range | −7 V to +12 V - enables reliable reception in electrically noisy spacecraft bays with ground potential shifts. |
| Input Sensitivity | ±200 mV - ensures valid logic decision even under marginal differential signal conditions on long cables. |
| Propagation Delay | 22–30 ns (CL = 15 pF) - guarantees tight timing alignment across all four channels in synchronous bus architectures. |
| Supply Voltage | +4.5 V to +5.5 V - compatible with standard space-grade 5 V power rails and tolerant of voltage droop. |
| Operating Temperature | −55°C to +125°C - qualified per MIL-STD-883 for use in orbital and deep-space thermal environments. |
| Input Hysteresis | 50 mV typical - suppresses false triggering from EMI-induced noise on differential pairs. |
Pinout & Package
DS96F175ME/883 is housed in a hermetically sealed 20-lead Ceramic Leadless Chip Carrier (LCCC, package number NAJ0020A), with leads arranged in a 5×4 grid and soldered directly to metallized pads on ceramic substrates. The package provides radiation hardness, zero moisture ingress, and thermal stability for space applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | A1–A4 Inputs (non-inverting) | Differential input terminals for receivers 1–4; accept balanced signals referenced to common-mode range. |
| 5, 6, 7, 8 | B1–B4 Inputs (inverting) | Complementary differential inputs paired with A1–A4; define polarity and noise rejection path. |
| 9, 10 | E1, E2 Enables | Active-high enables controlling receivers 1&2 (E1) and 3&4 (E2); disable outputs to high-impedance state. |
| 11–14 | Y1–Y4 Outputs | TRI-STATE TTL-compatible outputs; drive loads up to 16 mA low / −400 µA high with defined VOH/VOL. |
| 15 | VCC | +5 V supply pin; bypassing required per MIL-STD-883 layout guidelines for transient suppression. |
| 16 | GND | Signal reference ground; must be connected to system star ground point to maintain common-mode integrity. |
| 17–20 | NC | No-connect pins; left unconnected per TI mechanical drawing NAJ0020A to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| L-FAST bipolar process | Enables 15 Mbps operation with <1.5 mA per receiver ICC at 5 V - reduces thermal load in sealed enclosures. |
| Separate enables per receiver pair | Allows dynamic channel gating in time-division multiplexed telemetry streams without affecting other receivers. |
| ±25 V absolute max input rating | Withstands lightning-induced transients and ESD events in launch vehicle interfaces without external clamping. |
| MIL-STD-883 Group A testing | Validated across 14 test subgroups including functional, dynamic, and settling tests at −55°C, +25°C, and +125°C. |
| Hermetic LCCC-20 package | Zero moisture permeability and <1 × 10⁻⁸ atm·cc/sec He leak rate - prevents internal corrosion during 15+ year missions. |
Applications
| Spacecraft Telemetry Receiver | Avionics Data Concentrator |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad EIA-485 receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS96F175MQML | Same die, identical electrical specs, but packaged in 16-pin CDIP (NFE0016A); no NC pins; lower pin count limits routing flexibility in dense layouts. | Preferred for legacy board designs with existing CDIP footprints and less stringent radiation tolerance requirements than 883-class. | Select DS96F175MQML only if CDIP-16 mechanical fit and non-883 compliance are acceptable for the target program. |
| AM26LS32 | Commercial-grade quad receiver; lacks MIL-STD-883 qualification, radiation hardening, and extended temperature range; 10 Mbps max data rate. | Suitable for ground-based lab equipment or non-flight subsystems where cost and availability outweigh environmental robustness. | Use AM26LS32 only in non-mission-critical terrestrial prototypes - not for flight hardware or space-qualified systems. |
Compared with DS96F175MQML and AM26LS32, the DS96F175ME/883 uniquely delivers hermetic LCCC-20 packaging, full MIL-STD-883 Class B screening, and guaranteed 15 Mbps performance across −55°C to +125°C - making it the sole option for flight-critical EIA-485 receivers in DoD and NASA programs.

FAQ
What is the qualified temperature range for DS96F175ME/883?
The DS96F175ME/883 is fully qualified per MIL-STD-883 for operation from −55°C to +125°C. All electrical parameters - including propagation delay, input thresholds, and output drive - are tested across this full range in Groups 1–3 (static), 4–6 (dynamic), and 7–14 (functional/settling) per the datasheet's Quality Conformance Inspection table. This makes DS96F175ME/883 suitable for deep-space probe thermal cycling and high-altitude avionics bays.
Does DS96F175ME/883 support EIA-485 half-duplex bus termination?
Yes, DS96F175ME/883 supports EIA-485 half-duplex operation when used with external drivers like the DS96F174 or SN75ALS176. Its high input impedance (>10 kΩ), ±200 mV sensitivity, and −7 V to +12 V common-mode range allow proper receiver biasing and fail-safe detection on terminated buses. The DS96F175ME/883 itself does not integrate bus termination resistors - those must be placed externally per Figure 8 in the datasheet.
How does the enable architecture of DS96F175ME/883 differ from DS96F173ME/883?
DS96F175ME/883 features two independent active-high enables (E1 for receivers 1&2, E2 for receivers 3&4), allowing granular channel control. In contrast, DS96F173ME/883 uses a single enable pin with both active-high and active-low logic inputs shared across all four receivers. This architectural difference means DS96F175ME/883 supports true per-pair power gating in time-sliced communication protocols, while DS96F173ME/883 is better suited for global bus enable/disable scenarios.
Is DS96F175ME/883 pin-compatible with commercial equivalents like SN75175?
No, DS96F175ME/883 is not pin-compatible with SN75175. While functionally similar as quad EIA-485 receivers, DS96F175ME/883 uses a 20-pin LCCC (NAJ0020A) package with NC pins at positions 17–20, whereas SN75175 uses a 16-pin DIP or SOIC package. Pin mapping, thermal pad configuration, and enable logic differ fundamentally - direct PCB replacement requires layout redesign and validation per MIL-PRF-38535.
What is the maximum data rate guaranteed for DS96F175ME/883 under worst-case conditions?
The DS96F175ME/883 guarantees 15 Mbps operation under worst-case conditions: VCC = 4.5 V, TA = +125°C, CL = 15 pF, and common-mode voltage = ±12 V. This is confirmed by AC parameter testing in Subgroup 2 and 3 of MIL-STD-883, with tPHL/tPLH propagation delays bounded at 30 ns. Performance degrades to ~10 Mbps at −55°C due to carrier mobility limits in the L-FAST process.
