Product details

Overview

5962-9450901QKA from Texas Instruments is a military-grade 10-bit noninverting 3-state bus buffer with dual active-low output-enable inputs (OE1, OE2), BiCMOS EPIC-II^B architecture, ±32-mA high-drive outputs, and operation across −55°C to 125°C for wide-data-path parity bus interfacing in avionics and defense computing systems.

For engineers reviewing the 5962-9450901QKA datasheet, 5962-9450901QKA pinout, 5962-9450901QKA application, or 5962-9450901QKA equivalent, this page delivers verified electrical specs, CFP package terminal mapping, military temperature validation, flow-through PCB layout advantages, and direct alternatives for legacy system sustainment and radiation-tolerant design.

Technical Context

This device implements a dual-input AND logic gate for 3-state control: either OE1 or OE2 high forces all ten Y outputs into high-impedance, enabling precise bus arbitration. Its BiCMOS EPIC-II^B process delivers low ground bounce (VOLP < 1 V) and latch-up immunity exceeding 500 mA per JESD-17.

It features power-up/power-down high-impedance behavior below 2.1 V VCC and requires external pullup on OE for guaranteed Z-state above that threshold. Switching performance is characterized at CL = 50 pF, with tPLH/tPHL ≤ 4.9 ns and enable/disable times (tPZH/tPLZ) ≤ 7.1 ns at VCC = 5 V and TA = 25°C.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4.5 V to 5.5 V - Ensures compatibility with standard 5-V TTL/CMOS logic rails and stable operation under supply variation.
IOH / IOL	−32 mA / 64 mA - Supports driving heavy capacitive loads and multiple TTL inputs without signal degradation.
tPLH / tPHL	1.1 ns (min) to 4.9 ns (max) - Enables high-speed data transfer in wide parallel buses up to ~200 MHz effective throughput.
VIH / VIL	2.0 V / 0.8 V - Matches standard TTL input thresholds, allowing direct interface with legacy 5-V logic families.
Operating Temp	−55°C to 125°C - Qualified per MIL-PRF-38535 for use in harsh-environment military, aerospace, and ground vehicle systems.
VOH / VOL	≥2.0 V (IOH = −32 mA) / ≤0.55 V (IOL = 64 mA) - Guarantees robust noise margins (>0.4 V) under full drive conditions.
Input Clamp	IIK = −18 mA - Protects inputs against transient overvoltage events common in ruggedized board environments.

Pinout & Package

Ceramic Flatpack (CFP) package, 24-lead, hermetically sealed, compliant with MIL-STD-1835 GDIP3-T24 and JEDEC MO-058 AA/AB. Designed for high-reliability, low-outgassing applications requiring long-term stability under thermal cycling and vacuum.

Pin/Terminal	Circuit Role	Design Meaning
1, 13	OE1, OE2	Active-low 3-state enable inputs; either high disables all outputs - enables flexible bus arbitration via discrete logic or microcontroller GPIO.
2–11	A1–A10	Noninverting data inputs - accepts true logic levels directly from upstream bus drivers or registers.
14–23	Y1–Y10	High-drive buffered outputs - deliver full swing, low-impedance signals to downstream data paths or memory interfaces.
12	GND	Digital ground reference - must be connected to system ground plane with low-inductance path to minimize switching noise.
24	VCC	Positive supply - requires local 5-V decoupling (0.1 µF ceramic + 4.7 µF tantalum) adjacent to pin for stable operation.
NC (pins 3, 4, 5, 6, 7, 8, 9, 10, 11, 15, 16, 17, 18, 19, 20, 21, 22)	No internal connection	Unused pins are unconnected die bond pads - must remain floating or grounded per board layout rules; no routing required.

Key Features

Feature	Design Value
EPIC-II^B BiCMOS Process	Reduces static power by >50% vs. bipolar-only equivalents while retaining high-speed drive capability and latch-up immunity.
Flow-Through Pinout	Input A1–A10 on left side, outputs Y1–Y10 on right side - minimizes trace crossovers and simplifies 2-layer PCB routing for dense backplanes.
Power-Up/Down Z-State	Guaranteed high-impedance when VCC ∈ [0, 2.1 V] - prevents bus contention during power sequencing in multi-rail systems.
High-Drive Outputs	−32 mA IOH / 64 mA IOL - drives 10+ TTL loads or 30+ pF traces without external buffers, reducing component count.
Military Temperature Qualification	Tested and screened per MIL-PRF-38535 Class V - ensures parametric compliance and reliability across full −55°C to 125°C range.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 10-bit noninverting bus buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ54ABT827W	Identical die, same CFP package (W), identical military screening and marking - functionally and physically interchangeable.	Same qualification level (MIL-PRF-38535 Class V), identical temp range and reliability testing - suitable for drop-in replacement in existing designs.	Select SNJ54ABT827W if sourcing through legacy TI military distribution channels; both share identical lot traceability and test reports.
5962-9450901QLA	Same functional silicon but in ceramic DIP (JT) package - larger footprint, higher thermal resistance (θJA ≈ 67°C/W vs. CFP's ~100°C/W), no lead coplanarity guarantee.	Preferred where through-hole assembly, manual rework, or socket-based prototyping is required; less suitable for high-vibration environments.	Choose 5962-9450901QLA only when board-level mechanical constraints mandate DIP form factor or legacy socket compatibility.

Compared with 5962-9450901QKA, SNJ54ABT827W offers identical performance and reliability in the same CFP package, while 5962-9450901QLA trades compactness and vibration resistance for easier hand-soldering and socket use - selection depends strictly on mechanical integration requirements, not electrical capability.

FAQ

What is the operating temperature range specified for the 5962-9450901QKA?

The 5962-9450901QKA is fully characterized and qualified for operation from −55°C to 125°C, meeting MIL-PRF-38535 Class V requirements. This range is validated across all electrical parameters including VOH/VOL, propagation delay, and 3-state leakage, making it suitable for extreme-environment deployment in space, airborne, and ground-mobile platforms where ambient thermal swings exceed commercial limits.

Does the 5962-9450901QKA require external pullup resistors on its OE pins?

Yes - to ensure guaranteed high-impedance output state when VCC exceeds 2.1 V, OE1 and OE2 must be tied to VCC via external pullup resistors. The minimum resistor value is determined by the current-sinking capability of the driving source; TI recommends ≥1 kΩ for typical microcontroller GPIOs. Without pullups, outputs may inadvertently enable during partial power-up sequences.

Is the 5962-9450901QKA pin-compatible with commercial-grade SN74ABT827 variants?

No - the 5962-9450901QKA uses a 24-lead ceramic flatpack (CFP/W) package, whereas commercial SN74ABT827 parts use SOIC (DW), SSOP (DB), or TSSOP (PW) packages with different pin counts and layouts. Electrical functionality is identical, but PCB footprint, soldering process, and thermal profile are not interchangeable without redesign.

What is the maximum capacitive load the 5962-9450901QKA can drive while maintaining specified timing?

The 5962-9450901QKA's switching characteristics (tPLH, tPHL, tPZH, etc.) are specified with CL = 50 pF. While it can drive heavier loads due to its ±32-mA/64-mA drive strength, timing margins degrade linearly beyond 50 pF - for example, tPLH increases to ~6.5 ns at CL = 100 pF. For designs requiring strict <5-ns skew, keep total net capacitance ≤45 pF including trace, via, and receiver input.

How does the 5962-9450901QKA handle power sequencing in multi-rail systems?

The 5962-9450901QKA enters a guaranteed high-impedance state whenever VCC is between 0 V and 2.1 V, preventing bus contention during staggered power-up/down of 5-V and 3.3-V domains. However, because OE is not internally clamped, external pullups are essential to maintain Z-state once VCC rises above 2.1 V - this behavior is explicitly designed for safe integration into complex power-sequenced avionics architectures.
