Product details
Overview
JM38510/30109BEA from Texas Instruments is a dual J-K positive-edge-triggered flip-flop with complementary Q and Q̅ outputs, 16-pin CDIP package, -55°C to +125°C operating temperature range, and military-grade QML-38510 qualification for high-reliability aerospace and defense systems.
For engineers reviewing the JM38510/30109BEA datasheet, JM38510/30109BEA pinout, JM38510/30109BEA application, or JM38510/30109BEA equivalent, key selection considerations include its radiation-hardened design, dual independent clocked storage elements, direct set/reset control per section, and compatibility with legacy TTL logic families in harsh-environment digital control circuits.
Technical Context
The JM38510/30109BEA implements two identical J-K flip-flop sections sharing no internal logic-each with independent J, K, CLK, CLR, and PR inputs plus Q and Q̅ outputs. It operates synchronously on the rising edge of CLK and supports asynchronous active-low preset (PR) and clear (CLR) functions.
Designed for military and space applications, it meets MIL-PRF-38535 Class B requirements, features hermetically sealed ceramic dual-in-line packaging, and maintains full functionality across extended temperature extremes without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | LS-TTL compatible input thresholds and output drive capability for interoperability with standard 5V TTL systems. |
| Operating Temperature | -55°C to +125°C-enables deployment in spacecraft, avionics, and ground-based military electronics without thermal management overhead. |
| Supply Voltage | 4.5V to 5.5V-ensures stable operation under regulated 5V rails common in defense-grade power architectures. |
| Propagation Delay | 25 ns max (CLK to Q)-supports synchronous timing at up to ~20 MHz in critical control loops. |
| Output Drive | IOH = -0.4 mA / IOL = 8 mA-sufficient fan-out for driving multiple LS-TTL inputs or discrete interface circuitry. |
| Qualification Standard | QML-38510 Class B-certified for high-reliability applications requiring screening, lot traceability, and failure rate data per MIL-HDBK-217F. |
Pinout & Package
Ceramic Dual-In-Line Package (CDIP), 16-pin, hermetically sealed, with 0.3-inch body width and 0.1-inch lead pitch. Pin 1 marked by notch or dot; pins arranged in two parallel rows.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1CLR | Asynchronous active-low clear for first flip-flop-forces Q1 low regardless of clock state. |
| 2 | 1CLK | Positive-edge-triggered clock input for first flip-flop-samples J1/K1 on rising transition. |
| 3 | 1J | Data input controlling set behavior of first flip-flop when CLK rises. |
| 4 | 1K | Data input controlling reset behavior of first flip-flop when CLK rises. |
| 5 | 1Q̅ | Inverted output of first flip-flop-complementary to Pin 6, used for feedback or differential signaling. |
| 6 | 1Q | True output of first flip-flop-retains state until next valid clock edge or asynchronous control event. |
| 7 | GND | Signal reference and return path for all logic and power currents-must be low-impedance connection. |
| 8 | VCC | +5V supply rail-requires local decoupling capacitor due to switching current transients. |
| 9 | 2Q | True output of second flip-flop-functionally isolated from first section except shared VCC/GND. |
| 10 | 2Q̅ | Inverted output of second flip-flop-provides complementary signal without external inversion. |
| 11 | 2K | Data input for second flip-flop-operates identically to Pin 4 but for independent storage element. |
| 12 | 2J | Data input for second flip-flop-enables separate J-K control per section. |
| 13 | 2CLK | Positive-edge-triggered clock for second flip-flop-allows independent timing control from Pin 2. |
| 14 | 2CLR | Asynchronous active-low clear for second flip-flop-no effect on first section. |
| 15 | 2PR | Asynchronous active-low preset for second flip-flop-sets Q2 high independently. |
| 16 | 1PR | Asynchronous active-low preset for first flip-flop-sets Q1 high without clock dependency. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent J-K flip-flops | Enables two synchronized but electrically isolated storage channels in one package-reduces board area and interconnect complexity in redundancy-critical systems. |

FAQ
What is the qualified temperature range for JM38510/30109BEA?
The JM38510/30109BEA is qualified for continuous operation from -55°C to +125°C. This full military temperature range is verified per MIL-STD-883 test methods and applies to all electrical parameters in the device's datasheet. The specification ensures reliable performance in spacecraft thermal vacuum chambers, jet engine bays, and arctic ground stations without thermal derating. JM38510/30109BEA maintains timing and voltage thresholds across this entire span.
Is JM38510/30109BEA pin-compatible with commercial SN74LS109A variants?
No-JM38510/30109BEA uses a 16-pin CDIP (J) package with 0.3-inch width and hermetic sealing, whereas SN74LS109A variants use PDIP (N), SOIC (D), or SO (NS) packages with different pin pitches, body dimensions, and moisture sensitivity levels. While logic function and pin numbering match, physical mounting, thermal dissipation, and PCB footprint are incompatible. JM38510/30109BEA requires dedicated military-grade layout rules.
Does JM38510/30109BEA support master-slave or toggle operation?
Yes-JM38510/30109BEA supports toggle mode when both J and K inputs are held high, causing Q to invert on each positive clock edge. It also supports master-slave behavior through cascaded configurations using Q outputs to drive downstream clocks, though it is not internally structured as a master-slave pair. The device's dual independent sections allow flexible implementation of sequential logic functions without external gating. JM38510/30109BEA's truth table confirms toggle, set, reset, and hold modes.
What qualification standard does JM38510/30109BEA meet?
JM38510/30109BEA meets MIL-PRF-38535 Class B requirements, including screening for burn-in, temperature cycling, steady-state life, and radiation hardness assurance per applicable test methods. It carries QML-38510 certification, which mandates lot traceability, failure analysis, and reliability modeling compliant with MIL-HDBK-217F. This qualification is documented in TI's QML listing and verified by independent government audit-not derived from commercial-grade testing. JM38510/30109BEA's certificate number is assigned per lot.
Can JM38510/30109BEA be used with 3.3V logic systems?
No-JM38510/30109BEA is strictly a 5V TTL device with input thresholds centered at 1.4V and output swing referenced to 5V VCC. Its minimum supply voltage is 4.5V; operation below that violates absolute maximum ratings and causes undefined logic states. Interfacing with 3.3V systems requires level-shifting circuitry such as TI's SN74LVC4245 or discrete resistor-divider networks with appropriate noise margin analysis. JM38510/30109BEA must be powered from a clean, regulated 5V source.
