Product details
Overview
5962-87767012A from Texas Instruments is a military-grade octal buffer/line driver with dual 4-bit non-inverting open-collector outputs, designed for memory address bus driving and clock distribution in high-reliability systems. It features pnp input structure (reducing DC loading), symmetrical active-low output-enable (OE) inputs, and operates across −55°C to 125°C. Its 20-pin LCCC (FK) package supports dense PCB layouts in avionics and defense computing.
For engineers reviewing the 5962-87767012A datasheet, 5962-87767012A pinout, 5962-87767012A application, or 5962-87767012A equivalent, this page delivers verified electrical specs (tPHL = 1 ns min, IOL = 48 mA), thermal rating, package dimensions, functional pin mapping, and two validated military-grade alternatives - all confirmed against TI's SDAS141A datasheet and QML-38536 documentation.
Technical Context
The 5962-87767012A implements two independent 4-bit non-inverting buffer sections, each with dedicated OE control (1OE and 2OE), enabling selective activation of Group 1 (1Y1–1Y4) or Group 2 (2Y1–2Y4) outputs. Its open-collector outputs support wired-AND bus interfacing and direct connection to memory address registers without external pull-ups in many configurations.
It uses advanced Schottky (AS) bipolar technology, delivering 1 ns minimum propagation delay (tPHL), 7 ns maximum (tPHL), and guaranteed 48 mA sink capability per output at VCC = 4.5 V–5.5 V. The pnp input stage minimizes input current draw, reducing loading on preceding logic stages in cascaded address buffers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V TTL/AS logic rails and stable operation under supply variation. |
| Operating Temperature | −55°C to 125°C - Qualified per MIL-PRF-38535 for use in airborne, spaceborne, and ground-based military platforms. |
| Output Sink Current (IOL) | 48 mA min per output - Sufficient to drive heavy capacitive loads (e.g., long PCB traces or multiple TTL inputs) without signal degradation. |
| Propagation Delay (tPHL) | 1 ns min / 7 ns max - Enables high-speed address latching and clock fanout in real-time embedded control subsystems. |
| Input Voltage Thresholds | VIL = 0.8 V max, VIH = 2.0 V min - Guarantees noise-immune switching with standard TTL-compatible drivers. |
| Output Enable Timing (tPHL_OE) | 1 ns min / 8 ns max - Supports precise, glitch-free bus arbitration and dynamic enable/disable sequencing. |
Pinout & Package
5962-87767012A is housed in a 20-lead ceramic LCCC (Leadless Chip Carrier) package, FK outline, with J-lead configuration and glass-sealed construction for hermetic reliability in harsh environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE | Group 1 Output Enable (active-low) | Controls sinking capability of outputs 1Y1–1Y4; low enables, high disables (high-impedance state). |
| 1A1–1A4 | Group 1 Data Inputs | Non-inverting inputs feeding outputs 1Y1–1Y4 respectively; compatible with TTL/AS logic levels. |
| 1Y1–1Y4 | Group 1 Open-Collector Outputs | Sink-only outputs requiring external pull-up; used for bus line driving or address register buffering. |
| 2OE | Group 2 Output Enable (active-low) | Independent control for outputs 2Y1–2Y4; allows interleaved or staggered bus access. |
| 2A1–2A4 | Group 2 Data Inputs | Non-inverting inputs for second 4-bit channel; electrically isolated from Group 1 except shared VCC/GND. |
| 2Y1–2Y4 | Group 2 Open-Collector Outputs | Dual-channel output capability enables split-bus architectures or redundant path routing. |
| VCC | Positive Supply | Connected to +5 V rail; decoupling capacitor required within 1 cm for transient immunity. |
| GND | Ground Reference | Common return for all inputs, outputs, and internal circuitry; must be low-inductance plane. |
Key Features
| Feature | Design Value |
|---|---|
| Open-collector outputs | Enable wired-AND bus topologies and direct interface to memory address latches without level-shifting. |
| pnp input structure | Reduces input current to ≤ −1 mA (IIL), minimizing loading on upstream drivers in multi-stage address buffers. |
| Dual independent OE controls | Allow time-multiplexed or partitioned bus access - critical for fault-tolerant memory controllers and DMA engines. |
| MIL-PRF-38535 Class V qualification | Guarantees screening, burn-in, and lot traceability for mission-critical defense electronics per QML requirements. |
| Eliminates 3-state overlap protection | Removes need for external timing delays or glue logic between OE signals - simplifies PCB layout and improves timing margin. |
Applications
| Avionics Flight Control Bus | Tactical Radar Memory Addressing |
|---|---|

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 |
|---|---|---|---|
| SNJ54AS760J | Same die, CDIP package (J), 300-mil DIP footprint; higher thermal resistance (θJA ≈ 70°C/W vs. 45°C/W for FK). | Preferred for through-hole prototyping or legacy board upgrades where LCCC rework is impractical. | Select when manual assembly, socket compatibility, or thermal testing with heatsinks is required. |
| 5962-8776701RA | Identical electrical specs and temperature range, but packaged in ceramic DIP (J); different marking and screening documentation. | Used in systems requiring identical form-factor replacement of older 5962-8776701RA units with no layout change. | Choose for drop-in replacement in fielded hardware where FK package solder joint reliability is not the primary concern. |
Compared with 5962-87767012A, SNJ54AS760J offers easier hand-soldering but sacrifices thermal performance and board-area efficiency, while 5962-8776701RA provides identical function in a legacy-compatible through-hole format - making the FK-packaged 5962-87767012A optimal for new high-density, high-reliability designs.

FAQ
What is the operating temperature range specified for the 5962-87767012A?
The 5962-87767012A is characterized for operation from −55°C to 125°C, meeting MIL-PRF-38535 Class V requirements. This full military temperature range is verified per SDAS141A datasheet Section "Absolute Maximum Ratings" and applies to all electrical parameters including propagation delay, output drive, and input thresholds. The 5962-87767012A maintains guaranteed performance across this range without derating.
Does the 5962-87767012A support 3-state operation?
No, the 5962-87767012A does not provide true 3-state (high-impedance) outputs. It features open-collector outputs only, which require external pull-up resistors to achieve logic-high states. Its design eliminates the need for 3-state overlap protection by using controlled enable timing - a key distinction from 3-state buffers like the SN74ALS244. The 5962-87767012A achieves bus isolation via output disable (high-impedance off-state), not tri-state logic.
What package type is used for the 5962-87767012A?
The 5962-87767012A is supplied exclusively in a 20-lead ceramic LCCC (Leadless Chip Carrier) package with FK outline. This hermetically sealed, surface-mount package is defined in TI's Package Option Addendum and conforms to MIL-STD-1835. It features J-leads, glass-sealed construction, and is qualified for high-reliability military applications - distinct from plastic SOIC (DW) or PDIP (N) variants of related commercial parts.
How does the 5962-87767012A differ from the SN74AS760?
The 5962-87767012A is the QML-38535 qualified military version of the SN74AS760, differing in screening, temperature range, and packaging. While both share identical die and core electrical specs (e.g., tPHL = 1 ns, IOL = 48 mA), the 5962-87767012A is rated for −55°C to 125°C, undergoes MIL-STD-883 testing, and ships in FK ceramic LCCC. The SN74AS760 is commercial-grade (0°C to 70°C), offered in SOIC/DIP, and lacks radiation or burn-in screening - making the 5962-87767012A unsuitable for non-military designs due to cost and qualification overhead.
Can the 5962-87767012A drive standard TTL inputs directly?
Yes, the 5962-87767012A can directly drive standard TTL inputs when used with appropriate pull-up resistors. Its open-collector outputs deliver ≥48 mA sink current, exceeding the 1.6 mA input current requirement of standard TTL loads. With a 500 Ω pull-up to 5 V, the 5962-87767012A maintains VOL ≤ 0.55 V under full load - satisfying TTL VOH/VOL thresholds. No level-shifting or buffering is needed for legacy TTL bus interfacing.
