Product details
Overview
5962-9583201Q2A from Texas Instruments is a military-grade 3.3-V ABT octal edge-triggered D-type flip-flop with 3-state outputs, designed for high-reliability systems operating from −55°C to 125°C. It features bus-hold on all eight data inputs, Ioff and power-up 3-state for hot insertion, and supports mixed-mode signaling (5-V inputs/outputs with 3.3-V VCC). Used in avionics data buses and radiation-tolerant control logic.
For engineers reviewing the 5962-9583201Q2A datasheet, 5962-9583201Q2A pinout, 5962-9583201Q2A application, or 5962-9583201Q2A equivalent, this page delivers verified electrical specs, LCCC-FK package details, timing parameters at extended temperature, MIL-PRF-38535 compliance status, and validated alternatives for defense and space programs.
Technical Context
The 5962-9583201Q2A implements eight independent positive-edge-triggered D flip-flops with asynchronous output-enable control. Each channel latches data on CLK↑ and drives Q outputs only when OE is low; OE high forces all outputs into high-impedance state without affecting internal latch states.
It integrates bus-hold circuitry on all D inputs (±75 µA hold current at VCC = 3 V), eliminates need for external pull resistors, and meets JESD 17 latch-up immunity (>500 mA) and JESD 22 ESD ratings (2000-V HBM, 200-V MM). Designed for 3.3-V operation with 2.7–3.6-V VCC range and 5-V tolerant inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - Enables stable operation under unregulated battery supply down to 2.7 V in harsh environments. |
| Operating Temperature | −55°C to +125°C - Qualified per MIL-PRF-38535 for extended-temperature military and space applications. |
| Max Clock Frequency | 150 MHz at VCC = 3.3 V - Supports high-speed synchronous data capture in real-time control systems. |
| Output Drive (IOL) | 48 mA per output - Sufficient to drive heavy capacitive loads or multiple TTL inputs without buffering. |
| Input Clamp Voltage (VIK) | −1.2 V at II = −18 mA - Protects against negative transients during hot-swap or ESD events. |
| Bus-Hold Current | ±75 µA at VCC = 3 V - Actively holds floating D inputs at valid logic levels, eliminating external biasing components. |
| Propagation Delay (tPLH/tPHL) | 1.7 ns to 5.9 ns - Ensures tight timing margins in high-speed digital backplanes and test equipment. |
Pinout & Package
LCCC (Leadless Ceramic Chip Carrier) package, FK outline, 20-terminal ceramic hermetic package with side-brazed leads. Designed for high-reliability mounting on ceramic substrates or metal-core PCBs in aerospace and defense platforms.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1D–8D | Data inputs | Eight asynchronous D inputs with integrated bus-hold; tolerate 5-V signals while powered from 3.3-V VCC. |
| 1Q–8Q | Registered outputs | Eight edge-triggered Q outputs; placed in high-Z when OE is high, retaining internal state regardless of OE. |
| CLK | Clock input | Positive-edge-sensitive clock; triggers simultaneous latching of all eight D inputs into respective Q outputs. |
| OE | Output enable | Active-low control; enables/disables output drivers without affecting internal flip-flop states or clock operation. |
| VCC | Power supply | 3.3-V nominal supply; supports operation down to 2.7 V with full functionality and timing compliance. |
| GND | Ground reference | Digital ground return path; decoupling required near pin 10 for noise suppression in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-38535 Class V qualification | Fully tested per military specification including screening, burn-in, and lot acceptance testing for space-grade reliability. |
| Ioff and power-up 3-state | Prevents backflow current during power-down and forces outputs to high-Z at power-up, enabling safe hot insertion in live backplanes. |
| Mixed-mode signal interface | Accepts 5-V TTL-level inputs and drives 5-V loads while operating from 3.3-V supply - bridges legacy and modern voltage domains. |
| Output ground bounce (VOLP) | <0.8 V at VCC = 3.3 V, TA = 25°C - Minimizes noise coupling into adjacent logic and analog circuits. |
| Latch-up immunity | >500 mA per JESD 17 - Withstands transient overcurrent events common in avionics power rail disturbances. |

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 |
|---|---|---|---|
| SNJ54LVTH574FK | Identical die, same LCCC-FK package, identical MIL-PRF-38535 Class V screening - functionally identical part number variant. | No difference; both qualified for −55°C to +125°C operation in defense electronics. | Select 5962-9583201Q2A when traceability to specific QML lot documentation and DoD source approval is required. |
| SN54LVTH574J | Same logic function and timing, but CDIP-J package (dual in-line plastic); no hermetic seal or ceramic substrate. | Not suitable for high-humidity, vacuum, or high-vibration environments; limited to commercial/military board-level assemblies. | Choose SN54LVTH574J only for cost-sensitive ground-based systems where hermeticity and radiation tolerance are not required. |
Compared with SNJ54LVTH574FK, 5962-9583201Q2A offers identical performance and screening but distinct DoD-assigned nomenclature for procurement traceability; versus SN54LVTH574J, it provides superior environmental robustness via LCCC packaging and full MIL-PRF-38535 compliance.

Does the 5962-9583201Q2A support hot insertion in live backplane systems?
Yes, the 5962-9583201Q2A supports hot insertion via dual protection mechanisms: Ioff circuitry disables outputs during power-down to prevent damaging current backflow, and power-up 3-state forces outputs into high-impedance during power ramp-up. These features are explicitly validated in the SCBS688G datasheet and required for MIL-PRF-38535 Class V qualification of the 5962-9583201Q2A.
What package type is used for the 5962-9583201Q2A?
The 5962-9583201Q2A uses the LCCC (Leadless Ceramic Chip Carrier) package with FK outline - a 20-terminal hermetically sealed ceramic package with side-brazed leads. This package is specified in the TI PACKAGE OPTION ADDENDUM and confirmed in the 5962-9583201Q2A ordering information as the standard configuration for this military-grade variant.
Is the 5962-9583201Q2A compatible with 5-V logic interfaces?
Yes, the 5962-9583201Q2A supports mixed-mode signaling: its inputs tolerate up to 5.5 V, and its outputs drive 5-V TTL loads while operating from a 3.3-V VCC supply. This capability is documented in the "Support Mixed-Mode Signal Operation" feature section of the SCBS688G datasheet and applies directly to the 5962-9583201Q2A variant.
What is the bus-hold feature on the 5962-9583201Q2A used for?
The bus-hold feature on the 5962-9583201Q2A actively maintains valid logic levels (±75 µA hold current) on all eight D inputs when left floating, eliminating the need for external pullup/pulldown resistors.
