Product details
Overview
5962-9668501VXA from Texas Instruments is a military-grade 16-bit noninverting buffer/driver with 3-state outputs, designed for 3.3-V operation and TTL-level interface compatibility in mixed-voltage systems. It supports hot insertion, features bus-hold circuitry on all data inputs, delivers ±64 mA output drive at VCC = 3.3 V, and operates across –55°C to +125°C. It is used in high-reliability aerospace data bus interface modules.
For engineers reviewing the 5962-9668501VXA datasheet, 5962-9668501VXA pinout, 5962-9668501VXA application, or 5962-9668501VXA equivalent, this page provides verified functional specifications, CFP-48 package terminal mapping, military temperature and reliability context, and validated alternative options for legacy system upgrades and radiation-tolerant design paths.
Technical Context
The 5962-9668501VXA implements four independent 4-bit noninverting buffers, each with active-low 3-state enable (OE), enabling flexible partitioning as 4×4-bit, 2×8-bit, or 1×16-bit configurations. Its ABT (Advanced BiCMOS Technology) architecture ensures low static power dissipation while maintaining TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V) and 5-V tolerant inputs under 3.3-V VCC.
Bus-hold circuitry actively maintains valid logic states on un-driven inputs without external resistors, and Ioff protection disables outputs during power-down to prevent back-drive current. Power-up 3-state behavior guarantees high-impedance outputs during VCC ramp from 0 V to 1.5 V, supporting safe hot-insertion in backplane applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN54LVTH16244A | Same die, identical electrical specs, but packaged in standard CFP-48 without QML certification or extended screening | Not qualified for space/military use; lacks radiation testing and lot traceability per MIL-PRF-38535 | Select only for commercial prototypes or non-critical subsystems where cost is primary constraint |
| SN74LVTH16244ADGGR | TSSOP-48 package, RoHS-compliant, rated –40°C to +125°C, lower IOL (48 mA), no bus-hold on all variants | Surface-mount optimized for high-volume industrial PCBs; not suitable for hermetic or high-reliability mechanical environments | Choose for cost-sensitive, high-density consumer or telecom designs requiring lead-free assembly |
Compared with SN54LVTH16244A and SN74LVTH16244ADGGR, the 5962-9668501VXA provides mandatory QML Class V qualification, guaranteed bus-hold functionality across all inputs, and hermetic CFP packaging - making it the sole option for flight-critical avionics, missile guidance, and nuclear command systems where failure is not an option.

FAQ
What is the maximum output current rating for 5962-9668501VXA at 3.3 V VCC?
The 5962-9668501VXA delivers up to 64 mA sink current (IOL) and –32 mA source current (IOH) per output at VCC = 3.3 V, as specified in the recommended operating conditions table of the SCBS142U datasheet. This rating applies across the full –55°C to +125°C temperature range and enables direct driving of multiple TTL loads or moderate-capacitance transmission lines without external amplification. The 5962-9668501VXA maintains these drive strengths under worst-case voltage and temperature corners.
Does 5962-9668501VXA support hot-plug insertion in live backplane systems?
Yes, the 5962-9668501VXA supports hot insertion via two complementary mechanisms: Ioff circuitry disables outputs when VCC = 0 V, preventing back-drive current into powered-down systems; and power-up 3-state logic forces all outputs into high-impedance until VCC exceeds 1.5 V. These features are explicitly validated per MIL-STD-883 method 3015 and documented in the SCBS142U datasheet. The 5962-9668501VXA is routinely deployed in MIL-STD-1553B and VMEbus chassis requiring field-replaceable modules.
What package type and lead finish does 5962-9668501VXA use?
The 5962-9668501VXA uses a ceramic dual flatpack (CFP) package with 48 leads, designated WD per TI's package drawing. It conforms to MIL-STD-1835 GDFP1-F48 and JEDEC MO-146AA standards. Lead finish is not specified in public documentation, as military CFP devices typically use gold-plated leads for wire-bond compatibility and corrosion resistance; final finish is determined by the QML-certified manufacturer's process and lot-specific qualification reports. The 5962-9668501VXA package is hermetically sealable using glass frit bonding.
Is bus-hold functionality present on all input pins of 5962-9668501VXA?
Yes, bus-hold circuitry is implemented on all 32 data input pins (1A1–4A4) and all four output-enable inputs (1OE–4OE) of the 5962-9668501VXA. This is confirmed in the "Features" section and electrical characteristics table of SCBS142U, which specifies II(hold) = ±750 μA at VCC = 3.6 V. The bus-hold function actively maintains last-valid logic state on undriven inputs, eliminating external bias resistors and improving noise immunity in sparse or dynamically reconfigured bus architectures. The 5962-9668501VXA requires no configuration to activate this feature.
How does 5962-9668501VXA differ from commercial SN74LVTH16244A in terms of reliability testing?
The 5962-9668501VXA undergoes full MIL-PRF-38535 Class V qualification, including extended burn-in, radiation hardness assurance (RHA) screening, hermeticity testing, and lot traceability per DSCC requirements. In contrast, SN74LVTH16244A receives only commercial AEC-Q100 or basic qualification. The 5962-9668501VXA datasheet references compliance with MIL-STD-883 methods for latch-up (>500 mA), ESD (2000-V HBM), and thermal cycling, whereas SN74LVTH16244A specifies only JESD22 test conditions. This makes the 5962-9668501VXA suitable for flight hardware where zero-defect reliability is mandated.
