Product details

Overview

5962-8776701SA from Texas Instruments is a military-grade octal buffer/line driver with open-collector outputs, designed for bus line driving and memory address register buffering in high-reliability systems. It features dual 4-bit noninverting channels, symmetrical active-low output-enable (OE) inputs, and operates across −55°C to 125°C. Its pnp input structure reduces DC loading, and it eliminates need for 3-state overlap protection.

For engineers reviewing the 5962-8776701SA datasheet, 5962-8776701SA pinout, 5962-8776701SA application, or 5962-8776701SA equivalent, key selection criteria include military temperature range compliance, open-collector drive capability (64 mA sink), low propagation delay (1–7 ns), and CFP (W) ceramic flatpack packaging for hermetic reliability.

Technical Context

The 5962-8776701SA implements two independent 4-bit noninverting buffer sections, each controlled by its own active-low OE input (1OE and 2OE). Its open-collector outputs support wired-AND bus interfacing and direct connection to memory address latches without external pull-ups in many configurations.

It belongs to the SN54AS760 family and uses advanced Schottky (AS) logic technology, delivering higher speed and lower power than ALS variants. Input clamping diodes enable VIK = −1.2 V, supporting robust noise immunity and hot-swap tolerance in mission-critical backplane and avionics subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage (VCC)	4.5 V to 5.5 V - compatible with standard 5 V TTL/AS logic rails and tolerant of supply ripple in ruggedized power domains.
Operating temperature	−55°C to 125°C - qualified per MIL-PRF-38535 for space, avionics, and defense electronics with no derating required.
Output sink current (IOL)	64 mA - enables direct drive of terminated bus lines (e.g., 50 Ω) or multiple TTL inputs without external drivers.
Propagation delay (tPHL)	1 ns minimum, 7 ns maximum - ensures sub-8 ns timing margins for high-speed address/data strobing in real-time control systems.
Input clamp voltage (VIK)	−1.2 V - provides inherent negative transient suppression and supports safe operation during signal undershoot events.
Quiescent current (ICC)	20–32 mA (outputs high), 60–94 mA (outputs low) - reflects AS-family trade-off: higher static power for superior speed and drive strength.

Pinout & Package

Ceramic Flatpack (CFP), package code W, 20-pin, hermetically sealed, lead finish A42 (tin-lead), compliant with MIL-STD-1835. Designed for high-vibration, high-radiation, and long-lifecycle deployments.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE	Active-low output enable	Independent control of each 4-bit channel; low enables outputs, high places them in high-impedance state.
1A1–1A4, 2A1–2A4	Noninverting data inputs	Eight buffered inputs split into two groups; each maps 1:1 to corresponding Y outputs.
1Y1–1Y4, 2Y1–2Y4	Open-collector outputs	Eight open-drain outputs requiring external pull-up; support wired-OR/Wired-AND bus topologies.
VCC, GND	Power and reference	Single 5 V supply; ground pin placement minimizes switching noise coupling in high-density layouts.

Key Features

Feature	Design Value
Open-collector outputs	Enable direct bus arbitration, level translation, and wired-logic without external components in avionics backplanes.
pnp input structure	Reduces DC input loading to ≤1 µA (IIH), minimizing bus capacitance impact and improving fanout in large address trees.
No 3-state overlap requirement	Eliminates need for timing-critical OE sequencing-simplifies FPGA/CPLD interface design and improves system robustness.
MIL-PRF-38535 Class V qualification	Guarantees screening, testing, and traceability for flight-critical applications including launch vehicle control and satellite telemetry.

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal open-collector buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ54AS760W	Identical electrical specs, same CFP (W) package, but marked as SNJ54AS760W per TI's orderable device nomenclature; identical die and screening.	No functional difference - used interchangeably in DoD BOMs where part marking format differs per contract requirements.	Select when procurement documentation requires legacy SNJ prefix or specific DSCC drawing compliance.
5962-8776701RA	Same SN54AS760 functionality but in ceramic dual-in-line package (CDIP, J); slightly higher inductance leads and larger footprint.	Suitable for through-hole prototyping or legacy board rework where CFP reflow is unavailable; less suitable for high-frequency (>20 MHz) bus routing.	Choose for manual assembly environments or when matching existing CDIP-based avionics chassis layouts.

Compared with 5962-8776701SA, SNJ54AS760W offers identical performance and packaging but different marking convention, while 5962-8776701RA trades CFP hermeticity and RF performance for through-hole serviceability-neither is pin-compatible due to differing package geometries, though all share identical pin functions and logic behavior.

FAQ

What is the full military specification compliance status of the 5962-8776701SA?

The 5962-8776701SA is fully compliant with MIL-PRF-38535 Class V, qualified for operation from −55°C to 125°C, and screened per QML requirements for space and defense applications. It meets SMD 5962-87767 and is listed on the DSCC Qualified Products List (QPL) with full traceability, lot acceptance testing, and radiation hardness assurance documentation available upon request for the 5962-8776701SA.

Does the 5962-8776701SA support hot-swap or live-insertion in backplane systems?

The 5962-8776701SA supports limited hot-swap capability due to its input clamp voltage (VIK = −1.2 V) and open-collector architecture, which prevents bus contention during insertion. However, it lacks explicit hot-swap control circuitry; successful implementation requires external current-limiting resistors and staged power sequencing. System-level validation is required before deployment in live backplanes using the 5962-8776701SA.

Can the 5962-8776701SA be used as a direct replacement for the SN74ALS760 in commercial designs?

No-the 5962-8776701SA is a military-grade SN54AS760 variant with tighter AC/DC specs, wider temperature range, and CFP packaging; it is not a drop-in replacement for the commercial SN74ALS760 (SOIC/PDIP, 0°C–70°C). Electrical differences include higher IOL (64 mA vs. 24 mA), faster propagation (1–7 ns vs. 5–15 ns), and distinct input thresholds. Substitution requires full revalidation of timing, power, and thermal margins for the 5962-8776701SA.

What is the maximum capacitive load the 5962-8776701SA can drive while maintaining specified timing?

The 5962-8776701SA is characterized for CL = 50 pF with RL = 500 Ω, meeting tPHL ≤ 7 ns and tPLH ≤ 19.5 ns. Driving loads >50 pF increases propagation delay nonlinearly and may violate setup/hold windows in high-speed systems. For loads beyond 50 pF, TI recommends verifying timing margins empirically or adding series termination; the 5962-8776701SA does not specify guaranteed performance above this test condition.

Is there a RoHS-compliant version of the 5962-8776701SA available?

No-5962-8776701SA uses SnPb (A42) lead finish per MIL-STD-1835 and is exempt from RoHS under defense application waivers. TI does not offer a Pb-free variant of this exact part number. Alternate RoHS-compliant options include commercial SN74AS760DW (SOIC), but those lack military qualification, temperature range, and hermetic packaging required for the 5962-8776701SA's target applications.
