Product details
Overview
5962-9680901VXA from Texas Instruments is a radiation-tolerant, military-grade 16-bit ABT buffer/driver with 3-state outputs, designed for 3.3-V VCC operation while supporting 5-V TTL-level inputs and outputs. It features four independent 4-bit channels, bus-hold on all data inputs, integrated 22-Ω output series resistors, and Ioff hot-insertion support. It operates across –55°C to 125°C in a hermetic ceramic dual flatpack (WD) package and is used in avionics data bus interface modules.
For engineers reviewing the 5962-9680901VXA datasheet, 5962-9680901VXA pinout, 5962-9680901VXA application, or 5962-9680901VXA equivalent, key selection considerations include its MIL-PRF-38535 qualification, extended temperature range, bus-hold functionality eliminating external resistors, and compatibility with mixed-voltage (3.3-V/5-V) signal environments in safety-critical systems.
Technical Context
The 5962-9680901VXA implements four independent 4-bit noninverting buffers, each with an active-low 3-state output-enable (OE) input. Its ABT (Advanced BiCMOS Technology) architecture enables TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V) while operating from a 2.7–3.6-V supply, allowing direct interfacing between 3.3-V logic and legacy 5-V buses.
It integrates bus-hold circuitry on all 16 data inputs (A1–A4 per channel), eliminating need for external pullup/pulldown resistors, and includes Ioff protection that disables outputs during power-down to prevent backflow current. Power-up 3-state ensures high-impedance outputs during VCC ramp-up from 0 to 1.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - supports unregulated battery operation down to 2.7 V without functional degradation |
| Input Voltage Range | –0.5 V to 5.5 V - enables safe 5-V TTL input signaling into 3.3-V core logic |
| Output Drive | ±12 mA - sufficient to drive standard TTL loads and 50-pF transmission lines |
| Bus-Hold Current | ±75 µA at VI = 0.8 V / 2 V - maintains valid logic state on floating inputs without external components |
| Propagation Delay | 1.1 ns to 4.6 ns (tPLH/tPHL @ VCC = 2.7 V) - ensures timing compliance in high-speed 16-bit parallel interfaces |
| Hot-Insertion Support | Ioff ≤ ±100 µA at VCC = 0 - prevents damaging back-current during live board insertion |
| Operating Temperature | –55°C to 125°C - qualified for aerospace and defense platforms requiring extreme environmental resilience |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE | Active-low output enable | Controls 4-bit group output state independently; low = enabled, high = high-Z |
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Data inputs | 16 total inputs with bus-hold; tolerate 5-V signals while powered from 3.3-V VCC |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | True buffered outputs | Each has built-in 22-Ω series resistor to suppress overshoot/undershoot on PCB traces |
| VCC (Pins 7, 21, 28, 42) | Power supply | Distributed VCC pins minimize switching noise and improve PSRR across 16-bit bus |
| GND (Pins 4, 10, 15, 25, 31, 37, 45, 47) | Ground reference | Eight dedicated GND pins reduce ground bounce and enhance signal integrity |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-38535 Qualified | Fully tested per QML Class V requirements including screening, burn-in, and lot acceptance testing for space and defense use |
| Bus-Hold Inputs | Eliminates need for 16 external pullup/pulldown resistors, reducing BOM count and PCB area in avionics backplanes |
| Integrated Output Resistors | 22-Ω series termination on all 16 outputs reduces EMI and eliminates discrete R-series components for point-to-point routing |
| Mixed-Mode Signal Operation | Accepts 5-V TTL inputs and drives 5-V loads while powered from 3.3-V rail - enables seamless voltage translation without level shifters |
| Power-Up 3-State | Guarantees high-impedance outputs during VCC ramp from 0 to 1.5 V - prevents bus contention at system startup |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LVTH162244WD | Same die, identical electrical specs, same WD package, but not MIL-PRF-38535 qualified; lacks QML screening and radiation tolerance testing | Suitable for non-mission-critical military systems where full QML-V is not mandated | Select SNJ54LVTH162244WD only if radiation hardness and extended reliability testing are not required |
| 5962-9680901QXA | Same family, same WD package, but different output-enable configuration: OE pins assigned to groups 1&2 and 3&4 rather than individual 4-bit groups | Requires PCB layout revision due to altered OE pin mapping; incompatible pinout for drop-in replacement | Choose 5962-9680901QXA only when redesigning for consolidated OE control and verifying timing impact on group enable sequencing |
Compared with SNJ54LVTH162244WD and 5962-9680901QXA, the 5962-9680901VXA uniquely delivers full QML-V qualification with individual 4-bit OE control and guaranteed radiation tolerance-making it the sole option for flight-critical avionics where component-level reliability and pin-specific enable flexibility are mandatory.

FAQ
What is the qualified temperature range for the 5962-9680901VXA?
The 5962-9680901VXA is fully specified and qualified for continuous operation from –55°C to +125°C. This range is validated per MIL-PRF-38535 requirements and applies across all electrical parameters including propagation delay, drive strength, and bus-hold functionality. The 5962-9680901VXA maintains guaranteed performance without derating throughout this full military temperature range.
Does the 5962-9680901VXA support hot insertion, and how is it implemented?
Yes, the 5962-9680901VXA supports hot insertion via two complementary mechanisms: Ioff circuitry limits current to ±100 µA when VCC = 0, preventing backflow damage during live insertion; and power-up 3-state forces all outputs into high-impedance mode while VCC ramps from 0 to 1.5 V. These features are integral to the 5962-9680901VXA design and verified per MIL-STD-883 test methods.
How does the bus-hold feature on the 5962-9680901VXA eliminate external resistors?
The 5962-9680901VXA integrates active bus-hold circuitry on all 16 data inputs (A1–A4 per channel), providing ±75 µA dynamic hold current to maintain valid logic states on undriven or floating inputs. This eliminates the need for external pullup or pulldown resistors, directly reducing BOM cost and PCB footprint - a key advantage confirmed in the 5962-9680901VXA datasheet Section 6.3.
What packaging and sealing standard does the 5962-9680901VXA meet?
The 5962-9680901VXA uses a 48-lead ceramic dual flatpack (WD package) conforming to MIL-STD-1835 GDFP1-F48 and JEDEC MO-146AA. It is hermetically sealed using glass-frit bonding to a ceramic lid, achieving a leak rate <1×10⁻⁸ atm·cc/sec He, satisfying MIL-STD-883 Method 1014 for space and defense applications.
Can the 5962-9680901VXA interface directly between 3.3-V and 5-V logic domains?
Yes, the 5962-9680901VXA supports true mixed-mode operation: its inputs accept 0–5.5 V signals (including 5-V TTL), and its outputs drive 5-V loads while powered from a 2.7–3.6 V VCC rail. This capability is explicitly specified in the Recommended Operating Conditions table and Electrical Characteristics section of the 5962-9680901VXA datasheet.
