Product details
Overview
5962-9062501MSA from Texas Instruments is a military-grade octal noninverting buffer/line driver with dual 4-bit sections, 3-state outputs, active-low output-enable (OE) control, and BiCMOS architecture enabling 48 mA low-level output drive at −55°C to 125°C. It drives memory address buses and clock distribution lines in hardened avionics and defense computing systems.
For engineers reviewing the 5962-9062501MSA datasheet, 5962-9062501MSA pinout, 5962-9062501MSA application, or 5962-9062501MSA equivalent, key selection criteria include its CFP-20 ceramic flatpack package, MIL-STD-883 qualified operation, 5 V supply compatibility, high-current 3-state bus driving capability, and guaranteed performance across full military temperature range.
Technical Context
The 5962-9062501MSA implements two independent 4-bit noninverting buffers, each with dedicated active-low OE input controlling high-impedance output states. Its BiCMOS design combines bipolar input stages for low DC loading and CMOS output stages for fast switching and rail-to-rail drive capability.
It supports bus-oriented system architectures via symmetrical 3-state control, P-N-P input structure reducing input current draw, and ESD protection exceeding 2000 V per MIL-STD-883C Method 3015. Output timing is characterized for CL = 50 pF with tPLH/tPHL ≤ 5 ns and tPZL/tPHZ ≤ 9 ns over −55°C to 125°C.
Key Specifications

| Supply Voltage (VCC) | 4.5 V to 5.5 V - Ensures stable operation under regulated 5 V military power rails with ±10% tolerance. |
| Operating Temperature | −55°C to 125°C - Fully qualified for airborne, space, and ground-based defense platforms requiring extreme environmental resilience. |
| Low-Level Output Current (IOL) | 48 mA - Sustains robust drive into heavily loaded address or data buses without signal degradation. |
| Propagation Delay (tPLH/tPHL) | ≤ 5 ns @ 5 V, CL = 50 pF - Enables reliable timing in high-speed memory interface and clock fanout applications up to ~100 MHz. |
| Input Clamp Current (IIK) | −18 mA - Protects inputs against transient overvoltage events common in ruggedized electronic enclosures. |
| ICCZ (Quiescent Supply Current) | 4–10 mA - Low standby power consumption critical for thermally constrained military subsystems. |

Pinout & Package
5962-9062501MSA is supplied in a 20-pin Ceramic Flatpack (CFP-W) package with hermetic sealing and lead finish specified as "Call TI" per TI's packaging addendum. The package meets MIL-PRF-38534 Class K requirements for high-reliability applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE | Section 1 Output Enable (active-low) | Controls Y1–Y4 outputs; logic low enables pass-through from A1–A4, high places outputs in high-Z state. |
| 2OE | Section 2 Output Enable (active-low) | Controls Y1–Y4 of second buffer section independently, enabling selective bus isolation. |
| 1A1–1A4 | Section 1 Data Inputs | Noninverting inputs for first 4-bit buffer group; accept TTL-compatible logic levels. |
| 2A1–2A4 | Section 2 Data Inputs | Noninverting inputs for second 4-bit buffer group; electrically isolated from Section 1. |
| 1Y1–1Y4 | Section 1 Outputs | 3-state buffered outputs mirroring 1A1–1A4 when 1OE is low; high-Z otherwise. |
| 2Y1–2Y4 | Section 2 Outputs | 3-state buffered outputs mirroring 2A1–2A4 when 2OE is low; high-Z otherwise. |
| VCC | Positive Supply | 5 V power connection; decoupling required within 1 cm for noise immunity in high-speed operation. |
| GND | Ground Reference | Signal and power return path; must be low-inductance connection to minimize ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| State-of-the-art BiCMOS design | Reduces ICCZ quiescent current by >50% vs. legacy bipolar-only octal drivers, lowering thermal load in sealed chassis. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal noninverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-9062501MRA | Same electrical specs, but in 20-pin Ceramic DIP (CDIP-J) package instead of CFP-W. | CDIP-J offers easier manual prototyping and socket-based testing but lacks hermetic seal and higher thermal conductivity of CFP. | Select 5962-9062501MRA only for lab validation or non-hermetic chassis where board-level conformal coating suffices. |
| 5962-9062501M2A | Identical functionality and temperature range, packaged in 20-pin LCCC (FK) with surface-mount terminations. | LCCC enables higher-density layouts and superior high-frequency performance due to shorter internal leads and lower inductance. | Choose 5962-9062501M2A for new designs targeting automated SMT assembly and RF-noise-sensitive radar subsystems. |
Compared with 5962-9062501MRA (CDIP) and 5962-9062501M2A (LCCC), the 5962-9062501MSA (CFP-W) provides optimal thermal dissipation and hermetic reliability for conduction-cooled avionics modules, while retaining identical logic behavior and timing specs across all three variants.

FAQ
What is the operating temperature range of the 5962-9062501MSA?
The 5962-9062501MSA is fully characterized for operation from −55°C to 125°C per MIL-STD-883, making it suitable for deployment in uncontrolled environmental zones of aircraft, naval vessels, and armored vehicles. This range is verified through temperature cycling, burn-in, and parametric testing at extremes, and applies to all electrical specifications including propagation delay, output drive, and input thresholds. The 5962-9062501MSA maintains guaranteed performance without derating across this full interval.
Does the 5962-9062501MSA support 3.3 V logic interfaces?
No, the 5962-9062501MSA is designed exclusively for 5 V operation with recommended VCC of 4.5 V to 5.5 V and TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V). It does not support 3.3 V core logic directly; interfacing with 3.3 V devices requires level-shifting circuitry or a compatible 5 V tolerant FPGA I/O bank. The 5962-9062501MSA datasheet specifies no operation below 4.5 V, and VIH/VIL values are fixed relative to 5 V rails-not scalable to lower voltages.
What package type is used for the 5962-9062501MSA?
The 5962-9062501MSA uses a 20-pin Ceramic Flatpack (CFP-W) package with leads extending from two sides and a hermetically sealed ceramic body. Per TI's Package Option Addendum, this variant is designated "W" and conforms to MIL-PRF-38534 Class K reliability standards. The CFP-W package provides superior thermal conductivity and moisture resistance compared to plastic SOIC or PDIP alternatives, and is commonly used in high-reliability defense applications where long-term hermeticity is mandatory.
How many independent buffer sections does the 5962-9062501MSA contain?
The 5962-9062501MSA contains two independent 4-bit noninverting buffer sections, each with its own active-low output-enable input (1OE and 2OE). This allows separate control of outputs Y1–Y4 and Y1–Y4, supporting asymmetric bus arbitration, staggered enable sequencing, or dual-bus isolation. Each section operates identically-no shared internal resources-and both sections meet full military temperature and drive specifications simultaneously when enabled.
Is the 5962-9062501MSA pin-compatible with commercial SN74BCT244 variants?
Yes, the 5962-9062501MSA shares identical pinout and logic function with commercial SN74BCT244 variants in 20-pin packages (e.g., SOIC-DW, PDIP-N), including matching pin assignments for VCC, GND, OE, A, and Y terminals. However, differences exist in package construction (CFP-W vs. plastic), qualification level (MIL-STD-883 vs. commercial), and absolute maximum ratings (e.g., wider VI range for military version). PCB layout can reuse footprint geometry, but thermal and reliability validation must reflect the 5962-9062501MSA's hermetic CFP-W construction.
