Product details
Overview
5962-9758001QEA from Texas Instruments is a dual J-K positive-edge-triggered flip-flop with independent preset and clear inputs, operating across –55°C to 125°C. It features 16-pin CDIP (J package), 100 MHz max clock frequency, 3 ns setup time, 1 ns hold time, and TTL-compatible input/output levels. It is used in military-grade synchronous logic control, state machine sequencing, and digital counter design.
For engineers reviewing the 5962-9758001QEA datasheet, 5962-9758001QEA pinout, 5962-9758001QEA application, or 5962-9758001QEA equivalent, key selection criteria include military temperature range compliance, edge-triggered J-K functionality, dual independent flip-flop architecture, and CDIP packaging for high-reliability board-level integration.
Technical Context
This device implements two fully independent J-K flip-flops sharing no internal signal paths. Each flip-flop responds to the rising edge of its dedicated clock input (1CLK/2CLK) and supports asynchronous active-low preset (1PRE/2PRE) and clear (1CLR/2CLR) with priority over clocked operation. Data transfer occurs only on positive clock transitions when both PRE and CLR are high.
Logic behavior follows standard J-K truth table including toggle (J=K=H), set (J=H,K=L), reset (J=L,K=H), and hold (J=K=L) modes. Clock triggering is voltage-level–sensitive-not dependent on slew rate-and output propagation delays (tPLH/tPHL) are specified down to 3 ns at VCC = 5 V and CL = 50 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Dual independent J-K positive-edge-triggered flip-flops with asynchronous preset/clear |
| Operating Temperature | –55°C to 125°C - qualified for military/aerospace environmental stress screening |
| Max Clock Frequency | 100 MHz - enables high-speed synchronous logic in real-time control systems |
| Setup/Hold Time | 3 ns / 1 ns - defines minimum data stability window before/after clock edge for reliable sampling |
| Propagation Delay | 3–8 ns (tPLH/tPHL) - determines worst-case path delay in sequential logic chains |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V TTL power rails and noise margins |

Pinout & Package
5962-9758001QEA is supplied in a 16-pin Ceramic Dual-In-Line Package (CDIP, J package), hermetically sealed for moisture resistance and long-term reliability in harsh environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1CLR | Active-low asynchronous clear for first flip-flop - forces Q1 = L, Q1̅ = H regardless of clock or J/K |
| 2 | 1J | Data input J for first flip-flop - controls set behavior when CLK rises and PRE/CLR inactive |
| 3 | 1K | Data input K for first flip-flop - controls reset behavior and enables toggle mode when tied to J |
| 4 | 1CLK | Positive-edge-triggered clock for first flip-flop - samples J/K on rising transition |
| 5 | 1PRE | Active-low asynchronous preset for first flip-flop - forces Q1 = H, Q1̅ = L unconditionally |
| 6 | 1Q | True output of first flip-flop - reflects stored state after clock edge or async control |
| 7 | 1Q̅ | Complementary output of first flip-flop - always inverse of 1Q |
| 8 | GND | Ground reference for all logic and power connections |
| 9 | VCC | +5 V supply rail - powers internal TTL circuitry and output drivers |
| 10 | 2Q̅ | Complementary output of second flip-flop - always inverse of 2Q |
| 11 | 2Q | True output of second flip-flop - independent storage node synchronized to 2CLK |
| 12 | 2PRE | Active-low asynchronous preset for second flip-flop - operates identically to 1PRE |
| 13 | 2CLK | Positive-edge-triggered clock for second flip-flop - electrically isolated from 1CLK |
| 14 | 2K | Data input K for second flip-flop - functionally identical to 1K |
| 15 | 2J | Data input J for second flip-flop - functionally identical to 1J |
| 16 | 2CLR | Active-low asynchronous clear for second flip-flop - operates identically to 1CLR |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Preset/Clear | Independent active-low PRE/CLR per flip-flop enables immediate state initialization without clock dependency |
| J-K Toggle Mode | Grounding K and tying J high configures each section as a divide-by-2 counter - essential for frequency division |
| D-Type Emulation | Tying J and K together allows use as edge-triggered D flip-flop - increases functional flexibility in logic design |
| Military Temperature Range | Rated from –55°C to 125°C - meets MIL-PRF-38535 requirements for defense electronics deployment |
| CDIP Hermetic Packaging | Ceramic DIP (J package) provides superior thermal cycling endurance and hermetic seal against humidity ingress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual J-K flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JM38510/34102BEA | Identical electrical specs, same CDIP-J package, same –55°C to 125°C rating, but manufactured under different QML flow (Class B vs Class Q) | No functional difference - approved for same MIL-STD-883 test conditions and qualification levels | Select JM38510/34102BEA if procurement requires legacy QML Class B documentation traceability |
| SNJ54F109J | Same die, identical pinout and timing, but marked per older TI military part numbering convention (no 5962- prefix) | Functionally interchangeable - used in legacy designs where original BOM specifies SNJ54F109J | Choose SNJ54F109J for direct replacement in fielded hardware with unchanged documentation and lot history |
Compared with 5962-9758001QEA, JM38510/34102BEA offers equivalent performance with alternate QML certification lineage, while SNJ54F109J provides identical silicon in legacy marking format - both preserve full pin-and-function compatibility without layout or firmware changes.

FAQ
What is the maximum clock frequency supported by the 5962-9758001QEA?
The 5962-9758001QEA supports a maximum clock frequency of 100 MHz under recommended operating conditions (VCC = 4.5 V to 5.5 V, TA = –55°C to 125°C). This value is verified per the switching characteristics table in the official Texas Instruments SDFS047A datasheet and applies specifically to the CDIP-J packaged 5962-9758001QEA variant.
Does the 5962-9758001QEA support asynchronous reset and preset functions?
Yes, the 5962-9758001QEA provides independent active-low asynchronous preset (1PRE, 2PRE) and clear (1CLR, 2CLR) inputs for each flip-flop. These inputs override clocked operation and force defined output states regardless of J/K or clock activity - a core feature confirmed in the FUNCTION TABLE and absolute maximum ratings section of the SDFS047A datasheet.
What package type is used for the 5962-9758001QEA?
The 5962-9758001QEA uses a 16-pin Ceramic Dual-In-Line Package (CDIP) with J package drawing, as documented in TI's PACKAGE OPTION ADDENDUM. This hermetically sealed ceramic package ensures long-term reliability in high-humidity, high-vibration, and wide-temperature military environments.
How does the 5962-9758001QEA differ from the commercial SN74F109 variants?
The 5962-9758001QEA is the military-qualified version of the SN74F109, characterized for –55°C to 125°C operation, built to MIL-PRF-38535 Class Q standards, and supplied in hermetic CDIP packaging. In contrast, SN74F109 variants (e.g., D or N packages) are commercial-grade, rated 0°C to 70°C, and use plastic or non-hermetic enclosures - making 5962-9758001QEA unsuitable for non-military applications due to over-specification and cost.
Can the 5962-9758001QEA be used as a D-type flip-flop?
Yes, the 5962-9758001QEA can emulate a D-type flip-flop by connecting the J and K inputs of each section together. When J = K, the device behaves as an edge-triggered D flip-flop - a configuration explicitly described in the device description section of the SDFS047A datasheet and validated across the full military temperature range.
