Product details
Overview
5962-9559001QXA from Texas Instruments is a military-grade 16-bit inverting bus transceiver with 3-state outputs, designed for asynchronous bidirectional data transfer between A and B buses in high-reliability systems. It features dual 8-bit sections, ±32-mA/±64-mA drive capability, operation from –55°C to 125°C, and ceramic flatpack (WD) packaging for hermetic sealing.
For engineers reviewing the 5962-9559001QXA datasheet, 5962-9559001QXA pinout, 5962-9559001QXA application, or 5962-9559001QXA equivalent, key selection considerations include its MIL-PRF-38535 qualification, flow-through pinout for optimized PCB layout, latch-up immunity >500 mA, distributed VCC/GND for noise suppression, and compatibility with 5-V TTL logic interfaces in avionics and defense computing subsystems.
Technical Context
The 5962-9559001QXA implements two independent 8-bit bidirectional transceiver sections, each controlled by dedicated direction (1DIR/2DIR) and output-enable (1OE/2OE) inputs. Its EPIC-IIB BiCMOS process enables high-speed switching with low ground bounce (VOLP < 1 V at VCC = 5 V).
It supports asynchronous bus isolation via high-impedance state activation, requires pull-up on OE for power-up safety, and uses flow-through architecture with distributed power/ground pins to minimize simultaneous switching noise in dense backplane or module interconnect applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5-V TTL and CMOS logic rails without level-shifting. |
| Operating Temperature | –55°C to 125°C - qualified per MIL-PRF-38535 for use in extended-environment aerospace and defense platforms. |
| Output Drive | –32 mA IOH, +64 mA IOL - drives heavy capacitive loads (e.g., long traces, multiple receivers) while maintaining signal integrity. |
| Propagation Delay | tPLH/tPHL ≤ 4.1 ns (max) at VCC = 5 V - supports high-throughput data exchange in real-time control and instrumentation buses. |
| Input Clamp Current | –18 mA - protects against negative transients during hot-swap or ESD events without external diodes. |
| Latch-Up Immunity | >500 mA per JEDEC JESD-17 - prevents destructive latch-up under overvoltage or ground-bounce stress in mission-critical systems. |
| VOLP (Ground Bounce) | <1 V at VCC = 5 V, TA = 25°C - reduces false logic transitions caused by simultaneous output switching in multi-bit transfers. |
Pinout & Package
Ceramic dual flatpack (CFP), WD package: 48-lead, 380-mil body, 25-mil center-to-center lead spacing, hermetically sealable per MIL-STD-1835 GDFP1-F48 and JEDEC MO-146AA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (active-high) | Selects data flow direction per 8-bit section: L = B→A, H = A→B; enables true bidirectional operation without external logic. |
| 1OE, 2OE | Output enable input (active-low) | Drives outputs to high-impedance when high; tied to VCC via pull-up resistor for safe power-up isolation. |
| 1A1–1A8, 2A1–2A8 | Port A data inputs/outputs | First and second 8-bit bus interface side; electrically isolated from B ports when OE is asserted. |
| 1B1–1B8, 2B1–2B8 | Port B data inputs/outputs | Second 8-bit bus interface side; inverted relative to A-side signals per transceiver function. |
| VCC (Pins 7, 18, 28, 39) | Power supply | Distributed VCC pins reduce IR drop and high-frequency impedance, suppressing simultaneous switching noise. |
| GND (Pins 4, 10, 15, 21, 31, 42) | Ground reference | Multiple GND pins placed adjacent to VCC and I/O banks provide low-inductance return paths for fast edge rates. |
Key Features
| Feature | Design Value |
|---|---|
| Inverting transceiver architecture | Provides signal inversion across A↔B paths, enabling direct integration into differential or complementary bus topologies without external inverters. |
| Flow-through pinout | Input and output pins aligned on opposite sides of package (e.g., 1A1 at Pin 47, 1B1 at Pin 2) simplifies layer routing and minimizes trace crossovers on multilayer PCBs. |
| High-drive 3-state outputs | –32 mA / +64 mA drive strength maintains signal slew rate and noise margin across long stubs or unterminated lines in modular chassis designs. |
| Distributed VCC/GND configuration | Eight dedicated power/ground terminals suppress simultaneous switching output (SSO) noise, critical for deterministic timing in flight control computers. |
| MIL-PRF-38535 Class Q/V qualification | Meets screening, testing, and reliability requirements for space-qualified and high-integrity defense electronics, including burn-in and radiation hardness assurance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ABT16640WD | Identical electrical specs, same WD ceramic package, but not QML-certified; lacks full MIL-PRF-38535 Class Q screening and documentation traceability. | Acceptable for non-certified military prototypes or lab test fixtures where formal qualification isn't required. | Select SNJ54ABT16640WD only if QML documentation, lot traceability, and extended reliability testing are unnecessary. |
| SN74ABT16640DGGR | Commercial-grade (–40°C to 85°C), TSSOP-48 package; lower thermal resistance (θJA = 89°C/W) but no hermetic seal or radiation tolerance. | Suitable for ground-based industrial control or telecom infrastructure where environmental stress is moderate. | Choose SN74ABT16640DGGR for cost-sensitive, non-mission-critical designs requiring RoHS-compliant plastic packaging and higher volume availability. |
Compared with SNJ54ABT16640WD and SN74ABT16640DGGR, the 5962-9559001QXA delivers verified QML Class Q compliance, full temperature range coverage, and hermetic packaging-making it the sole option for flight-qualified hardware where certification evidence, radiation resilience, and extreme thermal cycling performance are mandatory.

FAQ
What is the qualification status of the 5962-9559001QXA?
The 5962-9559001QXA is a QML Class Q-qualified device per MIL-PRF-38535, certified for use in high-reliability military and aerospace applications. It undergoes rigorous screening including burn-in, temperature cycling, and parametric testing to ensure performance across –55°C to 125°C. Unlike commercial variants, the 5962-9559001QXA provides full traceability, lot-specific test reports, and conformance to defense procurement standards - essential for flight hardware acceptance.
Does the 5962-9559001QXA support hot-swap operation?
The 5962-9559001QXA supports controlled hot-swap operation when OE is held high (disabled) during insertion, leveraging its input clamp current rating of –18 mA and latch-up immunity exceeding 500 mA. However, TI recommends using external current-limiting resistors and sequencing controls to prevent bus contention. The 5962-9559001QXA itself does not include built-in hot-swap controllers or slew-rate limiting - those functions must be implemented externally per system-level requirements.
How does the flow-through architecture of the 5962-9559001QXA improve PCB layout?
The flow-through architecture of the 5962-9559001QXA aligns A-side inputs on one side (e.g., Pins 47–37, 36–26) and corresponding B-side outputs on the opposite side (e.g., Pins 2–12, 13–23), enabling straight-line trace routing without vias or crossovers. This reduces parasitic inductance, improves signal integrity for 100+ Mbps parallel transfers, and simplifies layer stackup in compact 6-layer avionics modules - directly lowering design cycle time and EMI risk compared to traditional zig-zag pinouts.
Can the 5962-9559001QXA be used as two independent 8-bit transceivers?
Yes, the 5962-9559001QXA contains two fully independent 8-bit transceiver sections (1A/1B and 2A/2B), each with dedicated DIR and OE controls. This allows concurrent bidirectional data flow - for example, transferring sensor data from Port A to Port B while simultaneously routing command packets from Port B to Port A. Each section operates at full speed (≤4.1 ns propagation delay) without crosstalk, making the 5962-9559001QXA ideal for dual-channel instrumentation or redundant bus architectures.
What are the recommended power-up sequencing guidelines for the 5962-9559001QXA?
TI specifies that OE must be held high (inactive) during power-up to ensure all outputs remain in high-impedance state until VCC stabilizes. This is achieved by tying OE to VCC through a pull-up resistor; minimum value depends on driver sink capability but typically ranges from 1 kΩ to 10 kΩ. The 5962-9559001QXA has no internal power-on reset - proper sequencing prevents bus contention and avoids false writes to downstream memory or peripherals during rail ramp-up.
