Product details
Overview
5962-9322001QRA from Texas Instruments is a military-grade octal edge-triggered D-type flip-flop with 3-state outputs, designed for high-speed bus interface and data latching in harsh-environment systems. It operates over −55°C to 125°C, delivers ±32-mA high-drive outputs, supports partial-power-down via Ioff, and features latch-up immunity >500 mA per JESD 17 - used in avionics data buffers and radiation-tolerant telemetry controllers.
For engineers reviewing the 5962-9322001QRA datasheet, 5962-9322001QRA pinout, 5962-9322001QRA application, or 5962-9322001QRA equivalent, this page provides verified functional identity, CDIP-20 package mapping, timing parameters (tsu = 1.5 ns, th = 1.8 ns), 3-state enable behavior, and MIL-PRF-38535-compliant electrical specifications.
Technical Context
This device implements eight independent positive-edge-triggered D flip-flops with a common clock (CLK) and shared output-enable (OE) control. Each Q output updates synchronously on CLK↑ while OE determines whether outputs drive logic levels or enter high-impedance state - enabling bidirectional bus arbitration without external pull-ups.
It uses ABT (Advanced BiCMOS Technology) logic with TTL-compatible inputs, 5-V supply operation, and Ioff circuitry that disables outputs during power-down to prevent backflow current. Ground bounce (VOLP < 1 V) and ESD robustness (2000-V HBM, 200-V MM) are specified per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Octal D-type flip-flop with 3-state outputs - enables synchronous data capture and bus isolation |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5-V TTL/CMOS systems and MIL-STD-883 requirements |
| Max Clock Frequency | 150 MHz - supports high-throughput data buffering in real-time avionics interfaces |
| Output Drive | −32 mA IOH / +64 mA IOL - drives heavy capacitive loads (e.g., backplane traces, long cables) without external buffers |
| Input Setup/Hold | tsu = 1.5 ns, th = 1.8 ns at VCC = 5 V - enables tight timing margins in fast synchronous designs |
| Operating Temperature | −55°C to +125°C - qualified per MIL-PRF-38535 for extended-range aerospace and defense applications |
| Ioff Support | Active at VCC = 0 V - prevents damaging current flow during hot-swap or partial-power-down sequences |
Pinout & Package
5962-9322001QRA is housed in a 20-pin Ceramic Dual In-line Package (CDIP-J), hermetically sealed for high-reliability military use. Pin spacing is 0.1 inch (2.54 mm), with standard DIP footprint and through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |

| 11, 12, 13, 14, 15, 16, 17, 18 | Outputs (1Q–8Q) | Registered Q outputs; driven low/high or placed in high-Z based on OE state |
| 19 | CLK | Global positive-edge clock input - triggers simultaneous update of all eight Q outputs |
| 20 | OE | Active-low output-enable - controls 3-state behavior without affecting internal register state |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop with 3-state output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ABT574FK | LCCC-20 ceramic package; identical logic, timing, and DC specs; lower thermal resistance (θJA = 45°C/W vs. CDIP's 72°C/W) | Better suited for conduction-cooled modules with limited airflow; requires different PCB land pattern and reflow profile | Select when board-level thermal management favors surface-mount LCCC over through-hole CDIP |
| 5962-9322001QSA | CFP-20 metal-ceramic package; same temperature range and MIL-PRF-38535 compliance; higher mechanical ruggedness but larger footprint | Preferred for vibration-prone platforms (e.g., helicopter avionics); not compatible with standard DIP sockets | Choose for extreme shock/vibe environments where hermetic CFP sealing outweighs size penalty |
Compared with SNJ54ABT574FK and 5962-9322001QSA, the 5962-9322001QRA offers optimal balance of socket compatibility, proven field reliability in CDIP form, and ease of manual rework - making it the preferred choice for legacy system upgrades and test-bench integration.

FAQ
What is the operating temperature range of the 5962-9322001QRA?
The 5962-9322001QRA is rated for −55°C to +125°C operation and fully tested per MIL-PRF-38535 requirements. This extended range ensures reliable performance in jet engine bays, satellite payload compartments, and other high-stress thermal environments where commercial-grade logic would fail.
Does the 5962-9322001QRA support partial-power-down operation?
Yes, the 5962-9322001QRA includes Ioff circuitry that actively disables outputs when VCC = 0 V, preventing damaging current backflow during hot-swap or staged power sequencing. This feature is verified per MIL-STD-883 Method 3001 and is critical for modular avionics architectures.
What package type is used for the 5962-9322001QRA?
The 5962-9322001QRA uses a 20-pin Ceramic Dual In-line Package (CDIP-J) with 0.1-inch lead pitch and hermetic ceramic body. It is socket-compatible with standard MIL-DTL-38510 footprints and supports through-hole assembly with wave or selective soldering.
How does the output-enable (OE) pin function on the 5962-9322001QRA?
The OE pin is active-low and places all eight Q outputs in high-impedance state without affecting internal flip-flop states. This allows new data to be loaded or retained while bus lines remain isolated - essential for glitch-free bus arbitration in MIL-STD-1553 and ARINC 429 systems.
Is the 5962-9322001QRA compliant with MIL-PRF-38535?
Yes, the 5962-9322001QRA is manufactured and tested to MIL-PRF-38535 Class V requirements, including full screening for radiation hardness, burn-in, and parametric verification across temperature extremes. Its QML certification ensures traceability and reliability for DoD and NASA programs.
