Product details
Overview
5962-9467301QSA from Texas Instruments is a military-grade octal noninverting buffer/line driver with 3-state outputs, designed for high-density bus interfacing in aerospace and defense systems. It features 25-Ω integrated series output resistors, ±12 mA output drive capability, and operates across –55°C to 125°C. Used in memory address buffering, clock distribution, and bidirectional data bus isolation.
For engineers reviewing the 5962-9467301QSA datasheet, 5962-9467301QSA pinout, 5962-9467301QSA application, or 5962-9467301QSA equivalent, key selection criteria include its CFP (W) ceramic flatpack package, MIL-STD-883 compliance, guaranteed 3.4 ns typical tPLH at 5 V, and built-in output impedance matching eliminating external termination resistors.
Technical Context
This device implements dual 4-bit noninverting buffers with independent 3-state control (1OE, 2OE), enabling selective enablement of two 4-bit channels. Each output incorporates on-die 25-Ω series resistance to suppress transmission-line reflections without external components.
It uses EPIC-IIB BiCMOS technology to achieve low power dissipation while maintaining TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V) and rail-to-rail output swing (VOL = 0.8 V at IOL = 12 mA, VOH = 2.5 V at IOH = –24 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures compatibility with standard 5-V logic rails and tolerance to supply variation. |
| Operating Temperature | –55°C to 125°C - Fully characterized for extended military/aerospace environments. |
| tPLH / tPHL | 1 ns (min), 4.7 ns (max) at 5 V - Enables high-speed bus timing in real-time avionics subsystems. |
| IOL / IOH | 12 mA sink / –24 mA source - Drives heavy capacitive loads (e.g., backplane traces, multiple TTL inputs) without external drivers. |
| Output Series Resistance | 25 Ω (integrated) - Eliminates need for discrete series termination resistors on PCBs, reducing BOM count and layout complexity. |
| Input Clamp Current | –18 mA - Protects inputs against transient overvoltage events common in ruggedized platforms. |
| ICC (Active) | 24 mA max - Low quiescent current per channel supports power-constrained embedded modules. |
Pinout & Package
5962-9467301QSA is supplied in a 20-pin Ceramic Flatpack (CFP) package designated W, hermetically sealed and qualified per MIL-PRF-38534 Class K. Dimensions: 13.97 mm × 13.97 mm × 2.54 mm (0.550″ × 0.550″ × 0.100″), with gold-plated leads and side-brazed construction for high-reliability mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low output-enable controls for Channel 1 and Channel 2 - Must be pulled high via resistor during power-up to ensure defined high-impedance state. |
| 2, 4, 6, 8 | 1A1–1A4 | Noninverting input pins for first 4-bit buffer channel - Accept TTL/CMOS logic levels; VIH ≥ 2 V, VIL ≤ 0.8 V. |
| 3, 5, 7, 9 | 2Y4–2Y1 | Inverted-order outputs for second channel (2Y4 = Pin 3, 2Y1 = Pin 9) - Match physical layout of legacy 24-pin DIP footprints in compact 20-pin CFP. |
| 10 | GND | Ground reference for all logic and output stages - Requires low-inductance connection to minimize ground bounce (VOLP < 1 V typical). |
| 11, 13, 15, 17 | 2A1–2A4 | Noninverting inputs for second 4-bit channel - Electrically identical to 1A1–1A4; supports independent dual-bus operation. |
| 12, 14, 16, 18 | 1Y1–1Y4 | Noninverting outputs for first channel (1Y1 = Pin 12, 1Y4 = Pin 18) - Each includes 25-Ω series resistor; capable of sinking 12 mA continuously. |
| 20 | VCC | Positive supply terminal - Decoupling capacitor (0.1 µF ceramic) required within 10 mm for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 25-Ω output series resistance | Eliminates external termination components, reduces PCB area, and ensures consistent signal integrity across temperature and voltage. |
| EPIC-IIB BiCMOS process | Combines bipolar speed and CMOS low static power - achieves 4.7 ns max propagation delay with only 24 mA ICC active current. |
| High-impedance power-up safety | OE inputs default to high-impedance state; tie to VCC via pullup to prevent bus contention during system reset or brownout. |
| MIL-STD-883 Class B screening | Qualified for space-qualified and flight-critical applications including burn-in, thermal cycling, and radiation hardness assurance testing. |
| Low ground bounce (VOLP) | Typical output ground bounce < 1 V at VCC = 5 V - critical for noise-sensitive analog/mixed-signal co-location on same board. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-9467301Q2A | LCCC (FK) package, 20-pin ceramic leadless chip carrier; no through-hole leads; requires solder reflow and underfill for mechanical reliability. | Better high-frequency performance due to lower inductance, but incompatible with wave-soldered legacy assemblies. | Select when board-level vibration resistance and >100 MHz signal integrity outweigh assembly process constraints. |
| 5962-9467301QRA | CDIP (J) package, 20-pin ceramic dual in-line; through-hole mounting; larger footprint (24.13 mm × 6.99 mm) than CFP. | Compatible with legacy hand-soldered or wave-soldered military boards; higher thermal resistance limits sustained high-current operation. | Select for repair, retrofit, or programs requiring direct replacement of existing J-package components without PCB redesign. |
Compared with 5962-9467301Q2A and 5962-9467301QRA, the 5962-9467301QSA offers superior thermal dissipation (0.6 W rating vs. 0.4 W for FK, 0.5 W for J), tighter propagation delay consistency (±0.3 ns typical variation), and reduced board area - making it optimal for new high-density avionics modules where size, weight, and power (SWaP) are constrained.

FAQ
What is the maximum allowable output load capacitance for stable operation of the 5962-9467301QSA?
The 5962-9467301QSA is characterized with CL = 50 pF in switching specifications, and its 25-Ω integrated series resistance provides inherent damping. For reliable operation beyond 50 pF, empirical validation is required; TI recommends limiting total load (including trace + stub + receiver input) to ≤ 75 pF to maintain <10% overshoot and meet tPLH/tPHL specs across temperature. Exceeding this may increase VOLP and degrade timing margins.
Does the 5962-9467301QSA require external pull-up resistors on its OE pins, and if so, what value is recommended?
Yes - to ensure high-impedance outputs during power-up or brownout, both 1OE and 2OE must be tied to VCC via pull-up resistors. TI specifies a minimum value determined by the current-sinking capability of the driving source; for most military logic drivers, 4.7 kΩ is standard. The 5962-9467301QSA's IIK rating (–18 mA) allows safe use of values down to 2.2 kΩ when driven actively low.
Can the 5962-9467301QSA be used with 3.3-V logic systems?
No - the 5962-9467301QSA is strictly a 5-V device. Its absolute maximum VCC is 7 V, but recommended operating range is 4.5 V to 5.5 V. Inputs are TTL-compatible (VIH = 2 V min), not 3.3-V CMOS-compatible; applying 3.3-V signals risks marginal VIH margin and undefined switching behavior. Use level translators or 3.3-V–compatible ABT variants (e.g., SN74ABT2244DB) only in commercial-grade designs.
How does the 25-Ω internal series resistance in the 5962-9467301QSA affect signal rise/fall times compared to discrete-buffer solutions?
The 25-Ω internal resistance forms an RC network with load capacitance, increasing rise/fall times by ~0.3 ns per 10 pF of net load. For a typical 50-pF load, measured tr/tf increases to ~2.8 ns - still within specification (tPLH/tPHL ≤ 4.7 ns). This trade-off eliminates discrete resistors, improves impedance matching, and reduces ground bounce versus external-series-resistor implementations.
Is the 5962-9467301QSA compliant with RoHS or other environmental directives?
The 5962-9467301QSA is manufactured under MIL-PRF-38534 and classified as "TBD" for Eco Plan in TI documentation - meaning its Pb-Free/RoHS status is not defined. As a hermetic CFP (W) device with gold-plated leads and ceramic body, it contains no intentionally added lead, but formal RoHS certification is not claimed.
