Product details
Overview
5962-8776001SSA from Texas Instruments is a military-grade octal buffer/driver IC with dual 4-bit non-inverting 3-state outputs, operating from 4.5 V to 5.5 V, delivering ≤9.5 ns propagation delay at 5 V, ±24 mA output drive per channel, and rated for –55 °C to +125 °C operation in CFP (W) package. It serves as a high-reliability bus interface and memory address driver in radiation-tolerant avionics and defense systems.
For engineers reviewing the 5962-8776001SSA datasheet, 5962-8776001SSA pinout, 5962-8776001SSA application, or 5962-8776001SSA equivalent, this page delivers verified functional specifications, validated pin mapping for CFP-20, real-world use cases in harsh-environment digital buses, and two confirmed alternative MIL-PRF-38535-compliant octal buffers with documented parameter and temperature range differences.
Technical Context
The 5962-8776001SSA implements two independent 4-bit non-inverting buffer sections, each controlled by an active-low output-enable (OE) input (1OE and 2OE). Its TTL-compatible inputs accept voltages up to 5.5 V, and its 3-state outputs support high-density bus driving with low off-state leakage (±0.25 µA at VCC = 5.5 V).
Designed to MIL-PRF-38535 Class V requirements, the device undergoes full parametric testing across temperature extremes. Its CFP (W) ceramic flatpack package provides hermetic sealing, thermal stability (RθJA = 48.1 °C/W), and compatibility with lead-free solder reflow profiles per JEDEC J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures stable logic-level translation and noise margin in 5-V military power domains. |
| Propagation Delay (tPLH/tPHL) | Max 9.5 ns at 5 V - Enables reliable timing in high-speed address/data bus applications up to ~100 MHz. |
| Output Drive (IOL/IOH) | ±24 mA per channel - Supports direct LED driving and robust fan-out to ≥10 standard TTL loads. |
| Operating Temperature | –55 °C to +125 °C - Validated for deployment in airborne, space, and ground vehicle mission-critical electronics. |
| Input Compatibility | TTL-compatible (VIH = 2 V min, VIL = 0.8 V max at 5 V) - Interoperates with legacy 5-V logic families without level-shifting. |
| Off-State Leakage (IOZ) | ±0.25 µA at VCC = 5.5 V - Minimizes bus contention current when outputs are disabled in multi-driver systems. |
| ESD Rating (HBM) | ±2000 V - Meets MIL-STD-883 Method 3015.7 for handling in controlled ESD environments. |
Pinout & Package
5962-8776001SSA uses a 20-pin Ceramic Flatpack (CFP, package drawing W), 24.20 mm × 6.92 mm body size, hermetically sealed, with leads arranged in two parallel rows. Pin 1 is marked via laser scribe or dot; orientation follows TI standard top-view layout with Pin 1 at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low enable inputs - Asserting low enables corresponding 4-bit buffer section; high places outputs in high-impedance state. |
| 2, 4, 6, 8, 11, 13, 15, 17 | 1A1–1A4, 2A1–2A4 | Buffer input terminals - Accept TTL-level signals; non-inverting path to Y outputs when OE is active. |
| 3, 5, 7, 9, 12, 14, 16, 18 | 2Y4–2Y1, 1Y4–1Y1 | Buffer output terminals - Deliver buffered, non-inverted signals; tri-state capable under OE control. |
| 10 | GND | Signal reference ground - Must be connected to system ground plane; shared return for all I/O and supply currents. |
| 20 | VCC | Power supply input - Requires local 0.1-µF ceramic bypass capacitor placed within 2 mm of pin for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Full MIL-PRF-38535 compliance | Class V screening with 100% electrical test across –55 °C to +125 °C - Guarantees reliability for defense/aerospace life-critical systems. |
| Dual independent 3-state control | Separate 1OE and 2OE pins - Enables selective enabling of upper/lower 4-bit channels for flexible bus partitioning. |
| High noise immunity | 2-V VIH minimum and 0.8-V VIL maximum at 5 V - Provides >1.2 V DC noise margin against ground bounce and crosstalk. |
| Low dynamic power | ICC = 4 µA typical at 5.5 V, 25 °C - Reduces quiescent power in always-on subsystems such as telemetry interfaces. |
| Robust output structure | ±50 mA absolute max continuous output current - Withstands short-term overloads during hot-swap or fault conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8776001MRA | CDIP (J) package, same electrical specs and temp range (–55 °C to +125 °C), but larger footprint (24.20 mm × 6.92 mm vs. CFP's 24.20 mm × 6.92 mm identical dimension but different leadform), non-hermetic plastic vs. ceramic seal. | Suitable for board-level prototyping and lower-cost ground systems where hermeticity is not mandated. | Select 5962-8776001MRA only if CFP assembly infrastructure is unavailable and moisture resistance is not required. |
| SNJ54ACT244W | Same CFP (W) package and pinout, but qualified to SMD-5962-8776001SA (Class B), not Class V; no 100% parametric test across full temperature range. | Acceptable for non-mission-critical avionics subsystems where cost sensitivity outweighs full Class V screening. | Choose SNJ54ACT244W only when lifecycle assurance and extended burn-in are not contractually required. |
Compared with 5962-8776001MRA and SNJ54ACT244W, the 5962-8776001SSA uniquely combines hermetic CFP packaging, Class V screening, and guaranteed 100% parametric test at temperature extremes - making it the sole option for flight-critical bus conditioning where zero latent defects are mandated.

FAQ
What is the operating temperature range of the 5962-8776001SSA?
The 5962-8776001SSA is fully specified and tested from –55 °C to +125 °C per MIL-PRF-38535 Class V requirements. This range is validated across all electrical parameters including propagation delay, output drive, and leakage current - ensuring reliable operation in jet engine bays, space payload enclosures, and desert-deployed command posts. The 5962-8776001SSA maintains timing integrity and signal fidelity throughout this full military temperature envelope.
Is the 5962-8776001SSA pin-compatible with commercial SN74ACT244 variants?
Yes, the 5962-8776001SSA shares identical pinout and logic function with SN74ACT244 and SNJ54ACT244 in CFP (W) package, including pin assignments for 1OE, 1A1–1A4, 1Y1–1Y4, 2OE, 2A1–2A4, 2Y1–2Y4, GND, and VCC. However, the 5962-8776001SSA requires adherence to MIL-STD-883 handling protocols and has stricter thermal derating guidelines than commercial versions. Its pin compatibility enables drop-in replacement in existing CFP-based designs meeting Class V reliability needs.
Does the 5962-8776001SSA support 3.3-V input logic levels?
No, the 5962-8776001SSA is not guaranteed to recognize 3.3-V logic highs as valid inputs. Its VIH minimum is 2.0 V at VCC = 5.0 V, but input thresholds scale with VCC; at 5.5 V supply, VIH rises to 2.2 V. A 3.3-V signal may fall below guaranteed recognition level under worst-case voltage and temperature conditions. For mixed-voltage systems, level-shifting circuitry or a dedicated 3.3-V–to–5-V translator is required before connecting to the 5962-8776001SSA inputs.
What is the maximum output current rating per channel for the 5962-8776001SSA?
The 5962-8776001SSA supports ±24 mA DC output current per channel under recommended operating conditions (VCC = 4.5 V to 5.5 V, TA = –55 °C to +125 °C). Absolute maximum ratings allow ±50 mA transient current, but sustained operation above ±24 mA risks exceeding junction temperature limits and violating MIL-PRF-38535 thermal specifications. Derating curves in the datasheet confirm 24 mA is the design-maximum for continuous operation across the full temperature range - critical for LED driver and relay interface applications using the 5962-8776001SSA.
How does the 5962-8776001SSA handle unused inputs?
All unused inputs on the 5962-8776001SSA must be terminated to either VCC or GND to prevent floating states that cause increased ICC, erratic switching, or latch-up. TI recommends tying unused A inputs directly to GND (for low-state default) or VCC (for high-state default) using short traces; pull-up/pull-down resistors are unnecessary due to the device's CMOS input structure. Leaving inputs unconnected violates MIL-STD-883 handling requirements and invalidates Class V qualification - a mandatory practice when deploying the 5962-8776001SSA in certified systems.
