Product details
Overview
5962-9450201QXA from Texas Instruments is a military-grade 16-bit bus transceiver and register with 3-state outputs, implementing dual 8-bit or single 16-bit bidirectional data flow, clocked storage (CLKAB/CLKBA), direction control (DIR), output enable (OE), and multiplexed real-time/stored data selection (SAB/SBA). It operates across –55°C to 125°C and delivers –32-mA IOH / 64-mA IOL drive strength for high-noise-margin system interconnects in avionics backplanes.
For engineers reviewing the 5962-9450201QXA datasheet, 5962-9450201QXA pinout, 5962-9450201QXA application, or 5962-9450201QXA equivalent, key selection criteria include its MIL-PRF-38535 qualification, WD ceramic flatpack package, latch-up immunity >500 mA, distributed VCC/GND pinning for low switching noise, and flow-through architecture enabling optimized PCB routing in space-constrained military computing modules.
Technical Context
The 5962-9450201QXA integrates two independent 8-bit bus transceiver/register blocks, each with separate clock (CLKAB/CLKBA), select (SAB/SBA), direction (DIR), and output-enable (OE) controls. Its EPIC-IIB BiCMOS process enables high-speed operation (125 MHz max clock frequency) while maintaining TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V) and low ground bounce (VOLP < 1 V).
It supports four core bus-management functions: real-time A→B/B→A transfer, storage of A/B data on clock edges, isolation with retained register state, and multiplexed output combining stored and live data-achieved via glitch-free select logic that eliminates decoding hazards during mode transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with standard 5-V military logic rails and tolerance to supply droop. |
| Operating Temperature | –55°C to 125°C - Fully characterized for extended-range deployment in airborne, missile, and ground vehicle electronics. |
| Output Drive | –32 mA IOH / 64 mA IOL - Sustains robust signal integrity driving long traces or multiple loads in noisy environments. |
| Propagation Delay | tPLH/tPHL ≤ 4.1 ns (CL = 50 pF) - Enables sub-8-ns round-trip latency for time-critical data handshaking. |
| Latch-Up Immunity | >500 mA per JESD 17 - Guarantees survivability under transient fault conditions without destructive latch-up. |
| Input Transition Rate | 10 ns/V - Supports clean edge interpretation even with slow-rising control signals from legacy subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit registered transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ABT16646W | MIL-PRF-38535 Class V qualified, same WD package and pinout, but rated only to 125°C (not –55°C); lacks full Q-level screening. | Suitable for non-safety-critical ground support equipment where extended low-temp operation is not required. | Select when cost sensitivity outweighs need for full Class Q qualification and extreme cold-start capability. |
| 5962-9315901Q2A | Same function and WD package, but based on older ABT technology-higher ICC (32 mA vs 2 mA typical quiescent), slower tPLH (5.5 ns), no EPIC-IIB noise reduction. | Acceptable for legacy redesigns where footprint compatibility is mandatory but performance headroom is available. | Choose only if backward compatibility with pre-1999 designs is essential and power/noise budgets allow degradation. |
Compared with SNJ54ABT16646W and 5962-9315901Q2A, the 5962-9450201QXA delivers superior low-temperature operation, lower ground bounce, tighter timing margins, and full Class Q screening-making it the sole choice for new flight-critical avionics and space-qualified systems requiring guaranteed reliability at –55°C.

FAQ
What is the operating temperature range specified for the 5962-9450201QXA?
The 5962-9450201QXA is fully characterized and tested over the extended military temperature range of –55°C to 125°C, per MIL-PRF-38535 requirements. This range is validated for all electrical parameters including propagation delay, drive strength, and input thresholds-ensuring reliable operation in stratospheric avionics, missile guidance systems, and orbital satellite electronics where ambient extremes are routine.
Does the 5962-9450201QXA support true bidirectional data flow without external logic?
Yes, the 5962-9450201QXA supports fully independent bidirectional data flow via dedicated DIR inputs per 8-bit section. When OE is low, DIR determines whether data transfers from A→B or B→A; both directions can be active simultaneously on separate halves of the device. No external direction-control logic is needed, simplifying board design and eliminating timing skew from discrete gates.
How does the 5962-9450201QXA prevent output glitches during multiplexer mode transitions?
The 5962-9450201QXA uses proprietary glitch-free select logic for SAB and SBA inputs. Unlike conventional multiplexers, its internal circuitry ensures no transient invalid states occur when switching between real-time and stored data paths. This is confirmed in the functional timing diagrams and eliminates the need for external synchronization or filtering-critical for deterministic behavior in safety-critical systems using the 5962-9450201QXA.
What package type and lead finish does the 5962-9450201QXA use?
The 5962-9450201QXA is supplied exclusively in the 380-mil fine-pitch ceramic flatpack (WD package) with 56 leads and 25-mil center-to-center spacing. Its leads are finished with solderable nickel-iron alloy (Kovar) compatible with gold-tin or lead-tin solder reflow profiles, meeting MIL-STD-883 requirements for hermeticity and thermal cycling endurance.
Is the 5962-9450201QXA compliant with MIL-PRF-38535, and what screening level does it meet?
Yes, the 5962-9450201QXA is fully compliant with MIL-PRF-38535 and qualified to Class Q standards-including radiation hardness assurance (RHA), 100% wafer lot testing, burn-in, and failure analysis traceability. All parameters are tested per Method 303, and the device carries full QML certification documentation required for DoD prime contractor acceptance.
