Product details

Overview

5962-9684901QXA from Texas Instruments is a military-grade 16-bit registered transceiver with 3-state outputs, designed for 3.3-V ABT operation and mixed-mode (5-V input/output with 3.3-V V_CC) interfacing in high-reliability systems. It features dual 8-bit or single 16-bit data flow, clocked register storage on CLKAB/CLKBA rising edge, bus-hold inputs eliminating external resistors, and I_off/power-up 3-state for hot insertion in avionics and defense backplanes.

For engineers reviewing the 5962-9684901QXA datasheet, 5962-9684901QXA pinout, 5962-9684901QXA application, or 5962-9684901QXA equivalent, this page delivers verified electrical specs, military temperature range (–55°C to 125°C), WD ceramic flatpack package details, timing parameters up to 150 MHz, and validated alternatives for legacy system sustainment and radiation-tolerant design reviews.

Technical Context

The 5962-9684901QXA implements Advanced BiCMOS Technology (ABT) for low static power and high-speed switching noise suppression via distributed V_CC/GND pins. Its dual-clock architecture supports independent A-to-B and B-to-A registered data transfer with separate CLKENAB/CLKENBA and OEAB/OEBA controls.

It integrates active bus-hold circuitry on all data inputs, ensures high-impedance during power-up/down when V_CC < 1.5 V, and meets MIL-PRF-38535 requirements including latch-up >500 mA and ESD >2000 V (MIL-STD-883, Method 3015).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Operating Range	2.7 V to 3.6 V - supports unregulated battery operation down to 2.7 V without functional degradation
Max Clock Frequency	150 MHz - enables high-throughput data buffering in synchronous backplane interfaces
Input Voltage Tolerance	–0.5 V to 7 V - allows safe 5-V TTL signal interfacing while powered from 3.3-V supply
I_off Current	±100 µA at V_CC = 0 - prevents damaging backflow current during hot-swap or partial power-down
Output Drive (I_OL)	96 mA per output - sufficient to drive heavy capacitive loads or multiple TTL inputs in legacy systems
Operating Temperature	–55°C to 125°C - qualified per MIL-PRF-38535 for aerospace, missile, and ground vehicle control units
Propagation Delay (t_PLH)	1.6 ns to 5.7 ns - ensures tight timing margins in high-speed register-to-register transfers
Bus-Hold Current	±75 µA - actively holds floating data lines at valid logic levels without external components

Pinout & Package

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
SNJ54LVTH16952WD	Same die, identical WD package, but marked per standard military drawing (5962-9684901QX instead of QXA); same –55°C to 125°C rating and MIL-PRF-38535 Class V screening.	No functional difference; used interchangeably in DoD procurement where QXA suffix denotes specific lot traceability or test report packaging.	Select SNJ54LVTH16952WD if sourcing through standard DSCC-qualified channels; 5962-9684901QXA is preferred when full QML-V documentation and radiation test reports are contractually mandated.
5962-0151901QXA	Pin-compatible 16-bit LVT transceiver (not ABT), lower max frequency (100 MHz), no bus-hold, higher I_CC (8 mA vs. 5 mA), same WD package and temperature range.	Suitable for non-critical timing paths where 50 MHz headroom is acceptable and external pullups can be added; lacks hot-insertion support.	Choose 5962-0151901QXA only when ABT-specific features (bus-hold, I_off, 150 MHz) are unnecessary and cost reduction is prioritized over design margin.

Compared with SNJ54LVTH16952WD, 5962-9684901QXA offers identical functionality but with enhanced traceability for QML-V programs; versus 5962-0151901QXA, it delivers 50% higher bandwidth, eliminates external biasing, and adds robust hot-swap capability-critical for field-upgradeable avionics.

FAQ

What is the maximum clock frequency supported by the 5962-9684901QXA?

The 5962-9684901QXA supports a maximum clock frequency of 150 MHz under recommended operating conditions (V_CC = 3.3 V ± 0.3 V). This specification is validated across the full military temperature range (–55°C to 125°C) and applies to both A-to-B and B-to-A registered data transfers in the 5962-9684901QXA device.

Does the 5962-9684901QXA support hot insertion, and how is it implemented?

Yes, the 5962-9684901QXA supports hot insertion via two integrated features: I_off circuitry disables outputs when V_CC = 0, preventing damaging current backflow, and power-up 3-state forces outputs into high-impedance during power ramp-up/down. These functions are inherent to the 5962-9684901QXA silicon design and require no external components.

What package type and lead finish does the 5962-9684901QXA use?

The 5962-9684901QXA is packaged in the 56-lead ceramic dual flatpack (WD) with a hermetic ceramic body and solderable leads. Per TI's packaging documentation, the lead finish is tin-lead (SnPb), consistent with MIL-PRF-38535 Class V requirements for military-grade reliability and solder joint integrity.

How does bus-hold functionality work on the 5962-9684901QXA, and what current does it provide?

The 5962-9684901QXA integrates active bus-hold circuitry on all A and B port data inputs, maintaining valid logic levels on floating pins without external resistors. It sources or sinks ±75 µA (minimum) at V_CC = 3 V, sufficient to override typical noise coupling and ensure stable input states in high-impedance bus environments.

Is the 5962-9684901QXA compliant with MIL-PRF-38535, and what screening level does it meet?

Yes, the 5962-9684901QXA is fully compliant with MIL-PRF-38535 and qualified to Class V standards. It undergoes rigorous testing including latch-up (>500 mA), ESD (>2000 V per MIL-STD-883 Method 3015), and extended temperature cycling, with full traceability and certification documentation provided for each lot of the 5962-9684901QXA device.
