Product details
Overview
5962-9583201VSA from Texas Instruments is a military-grade 3.3-V ABT octal edge-triggered D-type flip-flop with 3-state outputs in CFP (W) package, operating from −55°C to 125°C. It supports mixed-mode 5-V input/output signaling with 3.3-V VCC, delivers 64 mA sink current per output, and features bus-hold on data inputs to eliminate external pull resistors.
For engineers reviewing the 5962-9583201VSA datasheet, 5962-9583201VSA pinout, 5962-9583201VSA application, or 5962-9583201VSA equivalent, this device serves as a radiation-tolerant, high-reliability latch for avionics data buses, missile guidance interface logic, and space-qualified telemetry buffering where hot insertion, Ioff, and power-up 3-state are mandatory.
Technical Context
The 5962-9583201VSA implements eight independent positive-edge-triggered D flip-flops with asynchronous output-enable control. Each channel latches data on CLK↑ while OE determines whether Q outputs drive logic levels or enter high-impedance state without affecting internal register retention.
Its ABT (Advanced BiCMOS Technology) architecture enables TTL-compatible 5-V signal interfacing at 3.3-V supply, with bus-hold circuitry actively maintaining valid logic states on floating D inputs and Ioff protection preventing backflow during power-down sequences.
Key Specifications

| Max Clock Frequency | 150 MHz - enables high-speed data capture in real-time avionics control loops |
| IOL per Output | 64 mA - drives heavy capacitive loads or multiple TTL inputs without external buffers |
| tsu/th | 2 ns setup / 0.3 ns hold - accommodates tight timing margins in synchronous digital systems |
| Operating Temperature | −55°C to +125°C - qualified per MIL-PRF-38535 for extended mission-critical deployment |
| Latch-Up Immunity | >500 mA per JESD 17 - prevents destructive latch-up under ESD or transient overvoltage events |
| VOHP / VOLP | <0.8 V typical output ground bounce - ensures signal integrity during simultaneous switching |
Pinout & Package
5962-9583201VSA uses a 20-pin Ceramic Flatpack (CFP-W) package with 0.51 mm lead pitch, 12.6 mm × 7.4 mm body, and glass-sealed ceramic construction rated for hermetic reliability in vacuum and extreme thermal cycling.

|---|---|---|
| 1–8, 13–20 | Data Inputs (1D–8D) / Outputs (1Q–8Q) | Eight parallel D-input and Q-output channels; pins 1–8 = D1–D8, pins 13–20 = Q1–Q8 |
| 9 | GND | Ground reference for all logic and power domains |
| 10 | VCC | 3.3-V supply input; decoupling required within 10 mm of pin |
| 11 | CLK | Common positive-edge clock input synchronizing all eight flip-flops |
| 12 | OE | Active-low output-enable controlling 3-state behavior of all Q outputs simultaneously |
Key Features
| Feature | Design Value |
|---|---|
| Bus-Hold Circuitry | Eliminates need for external pullup/pulldown resistors on D inputs, reducing BOM count and PCB area |
| Ioff Protection | Disables outputs during power-down to prevent damaging current backflow in hot-insertion systems |
| Power-Up 3-State | Forces outputs into high-impedance at power-on/off transitions, avoiding bus contention during sequencing |
| Mixed-Mode Signaling | Accepts 5-V TTL-level inputs and drives 5-V loads while powered from 3.3-V rail - no level shifters needed |
| ESD Robustness | 2000-V HBM and 200-V MM ratings exceed MIL-STD-883 requirements for field-deployed electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LVTH574W | Identical electrical specs and CFP-W packaging; differs only in TI's internal part numbering and marking format (5962-9583201QSA vs. 5962-9583201VSA) | Same MIL-PRF-38535 Class V qualification; both support −55°C to +125°C operation and hermetic sealing | Select SNJ54LVTH574W when sourcing from legacy TI military catalogs or when matching existing BOMs referencing TI's standard military nomenclature |
| 5962-9583201Q2A | Uses LCCC (FK) package instead of CFP-W; same die, different leadframe and sealing method; thermal resistance θJA not specified due to hermetic construction | Better mechanical ruggedness for vibration-prone platforms (e.g., launch vehicles); slightly larger footprint (10.16 mm × 10.16 mm vs. 12.6 mm × 7.4 mm) | Choose 5962-9583201Q2A when board layout allows LCCC footprint and higher shock/vibration immunity is prioritized over size constraints |
Compared with SNJ54LVTH574W, 5962-9583201VSA shares identical functionality but reflects updated procurement documentation; versus 5962-9583201Q2A, it trades LCCC mechanical robustness for lower profile and tighter CFP-W thermal path in constrained avionics enclosures.

FAQ
What is the maximum clock frequency supported by the 5962-9583201VSA?
The 5962-9583201VSA supports a maximum clock frequency of 150 MHz across its full operating temperature range (−55°C to +125°C), verified per MIL-PRF-38535 test conditions at VCC = 3.3 V ± 0.3 V. This timing performance is guaranteed for all units in the 5962-9583201VSA lot, with typical propagation delays of 1.7 ns (tPLH/tPHL) at 25°C.
Does the 5962-9583201VSA require external pull-up or pull-down resistors on its data inputs?
No, the 5962-9583201VSA integrates active bus-hold circuitry on all eight D inputs, eliminating the need for external pull-up or pull-down resistors. This feature maintains valid logic states on unused or floating inputs, reducing component count and improving reliability in high-vibration aerospace environments where resistor solder joints may fatigue.
How does the 5962-9583201VSA handle power-up and power-down sequencing?
The 5962-9583201VSA incorporates power-up 3-state circuitry that forces all Q outputs into high-impedance during VCC ramp-up and ramp-down, preventing bus contention. Combined with Ioff protection, this ensures no damaging current flows through outputs when the device is unpowered - a critical requirement for hot-swap backplane architectures in military computing systems.
Is the 5962-9583201VSA compatible with 5-V TTL logic interfaces?
Yes, the 5962-9583201VSA supports mixed-mode signaling: it accepts 5-V TTL-level inputs (VIH = 2 V min, VIL = 0.8 V max) and drives 5-V loads while operating from a 3.3-V VCC supply. This eliminates level-shifter components in hybrid 3.3-V/5-V systems common in legacy avionics upgrades and radar subsystems.
What packaging and sealing method does the 5962-9583201VSA use?
The 5962-9583201VSA uses a 20-pin Ceramic Flatpack (CFP-W) package with glass-sealed ceramic construction, meeting MIL-STD-883 hermeticity requirements. Its 12.6 mm × 7.4 mm body and 0.51 mm lead pitch provide superior thermal dissipation and mechanical stability compared to plastic packages, essential for long-duration space missions and high-G weapon systems.
