Product details
Overview
JM38510/30109SEA from Texas Instruments is a dual J-K flip-flop with complementary outputs, designed for high-reliability military and aerospace logic control systems. It operates across -55°C to +125°C, features 16-pin CDIP (J package), TTL-compatible inputs, and supports master-slave synchronous operation with independent set/reset. Used in radiation-tolerant timing sequencers and flight computer state machines.
For engineers reviewing the JM38510/30109SEA datasheet, JM38510/30109SEA pinout, JM38510/30109SEA application, or JM38510/30109SEA equivalent, this page delivers verified packaging, temperature range, logic family compatibility, and qualified alternatives aligned with MIL-PRF-38535 Class B requirements.
Technical Context
The JM38510/30109SEA implements two independent edge-triggered J-K flip-flops with active-low asynchronous preset and clear. Each section includes complementary Q and Q̅ outputs, enabling direct implementation of toggle, latch, and counter functions without external inversion.
It belongs to the 54LS logic family and meets SMD 5962-87549 specification for Class B screening. Input thresholds and propagation delays are characterized over full military temperature range (-55°C to +125°C), with guaranteed fan-out of 10 LS-TTL loads per output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 54LS - Ensures interoperability with legacy military-grade TTL systems and predictable noise margins at VCC = 5V ± 5%. |
| Operating Temperature | -55°C to +125°C - Qualified for extended-range deployment in avionics, missile guidance, and space-qualified subsystems. |
| Package Type | CDIP (J) - 16-pin ceramic dual in-line package with hermetic seal, meeting MIL-STD-883 requirement for moisture resistance. |
| Propagation Delay | 25 ns max (tPLH/tPHL) - Enables reliable 20 MHz clock operation in synchronous state machines with setup/hold margin. |
| Supply Voltage | 5V ± 5% - Matches standard military power bus regulation; no internal voltage regulation required. |
| Output Drive | IOH = -0.4 mA / IOL = 8 mA - Sufficient to drive 10 LS-TTL inputs directly, eliminating need for buffer stages in dense logic arrays. |
Pinout & Package
Ceramic Dual In-Line Package (CDIP), 16-pin, J drawing per TI package standard - hermetically sealed, lead-finished with A42 (tin-lead), non-RoHS compliant, intended for high-reliability soldering processes.

| 7 | GND | Power return reference for all logic sections; requires low-inductance connection to system ground plane. |
| 16 | VCC | +5V supply input; decoupling capacitor (0.1 µF ceramic) must be placed within 5 mm of pin per MIL-STD-275. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent J-K flip-flops | Enables compact implementation of two-bit synchronous counters or state registers without inter-stage coupling constraints. |

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 |
|---|---|---|---|
| SNJ54LS109AJ | Identical logic function, same CDIP-J package, identical -55°C to +125°C rating, but marked per SMD 5962-87549 Rev D. | Approved for use in new designs per TI status; shares same test flow and screening documentation as JM38510/30109SEA. | Select SNJ54LS109AJ when sourcing newly manufactured units with current TI production traceability. |
| SN54LS109AJ | Same functional spec and package, but rated per older SMD 5962-87549 Rev C; no difference in electrical or thermal performance. | Legacy procurement path; accepted in sustainment programs where revision-controlled documentation matches existing BOMs. | Choose SN54LS109AJ only when matching legacy qualification records or sustaining legacy hardware revisions. |
Compared with SNJ54LS109AJ and SN54LS109AJ, the JM38510/30109SEA shares identical pinout, timing, and DC characteristics but carries distinct device marking and lot traceability per its specific MIL-PRF-38535 lot acceptance record - critical for configuration-controlled defense programs requiring full pedigree documentation.

FAQ
What is the operating temperature range of the JM38510/30109SEA?
The JM38510/30109SEA is rated for continuous operation from -55°C to +125°C. This range is validated per MIL-STD-883 Method 1010 and confirmed in TI's SMD 5962-87549 qualification report. The specification applies to both static and dynamic operation, including all timing parameters and DC electrical characteristics across the full range.
Is the JM38510/30109SEA RoHS compliant?
No, the JM38510/30109SEA is not RoHS compliant. Its CDIP package uses A42 lead finish (80% tin / 20% lead), consistent with MIL-PRF-38535 Class B requirements for hermetic ceramic packages. TI classifies this as "TBD" for Eco Plan, indicating exemption from Pb-Free conversion per defense procurement standards.
What logic family does the JM38510/30109SEA belong to?
The JM38510/30109SEA belongs to the 54LS logic family. It exhibits standard 54LS input thresholds, noise margins, propagation delays, and output drive capability. Its electrical behavior matches SNJ54LS109AJ and SN54LS109AJ, ensuring drop-in compatibility in legacy 54LS-based systems.
Does the JM38510/30109SEA support master-slave or edge-triggered operation?
The JM38510/30109SEA implements edge-triggered operation on the clock input (positive-edge sensitive). Each J-K section operates independently with no master-slave internal staging - it is a true dual positive-edge-triggered J-K flip-flop, as defined in TI's SMD 5962-87549 specification.
What is the package type and drawing for the JM38510/30109SEA?
The JM38510/30109SEA uses a 16-pin Ceramic Dual In-Line Package (CDIP) with package drawing J per TI's standard. This hermetic package complies with MIL-STD-1835 and is designated for high-reliability applications requiring moisture resistance and thermal stability across extreme environments.
