Product details
Overview
JM38510/30109SFA from Texas Instruments is a dual J-K flip-flop with complementary outputs, designed for high-reliability military and aerospace logic systems. It operates across -55°C to +125°C, features 16-pin CFP packaging, TTL-compatible inputs, and guaranteed propagation delay of ≤30 ns (max) at VCC = 5V. It serves as a synchronous edge-triggered storage element in radiation-tolerant timing and control circuits.
For engineers reviewing the JM38510/30109SFA datasheet, JM38510/30109SFA pinout, JM38510/30109SFA application, or JM38510/30109SFA equivalent, this page delivers verified package mapping, functional equivalence to SNJ54LS109AW, temperature-grade validation, and direct substitution guidance for legacy MIL-PRF-38535 Class S applications.
Technical Context
The JM38510/30109SFA implements two independent positive-edge-triggered J-K flip-flops with individual Set (SD) and Reset (RD) asynchronous inputs, each driving true and complemented Q/Q̅ outputs. All inputs are TTL-compatible with VIH = 2.0 V min and VIL = 0.8 V max.
It meets MIL-PRF-38535 Class S requirements, including screening per MIL-STD-883 Method 5005, burn-in, and lot acceptance testing. The device uses bipolar TTL process technology and supports single 5V ±5% supply operation with ICC = 34 mA max at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | LS-TTL - ensures compatibility with legacy 74LS-series control logic and predictable noise margins. |
| Operating Temperature | -55°C to +125°C - qualified for extended-range military and space vehicle avionics environments. |
| Propagation Delay | ≤30 ns (max) - guarantees deterministic state update timing in synchronous digital control loops. |
| Supply Voltage | 5V ±5% - requires stable regulated rail; no internal voltage regulation or wide-VCC support. |
| Output Drive | IOH = -0.4 mA / IOL = 8 mA - sufficient to drive 10 LS-TTL loads directly without buffering. |
| Package Type | 16-pin CFP (Ceramic Flatpack, TI drawing W) - hermetically sealed, lead-finished with A42 alloy for solderability and corrosion resistance. |
Pinout & Package
Package: 16-lead Ceramic Flatpack (CFP), TI package drawing W, hermetic ceramic body with parallel leads, 0.300" width, 0.050" lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 11, 12, 13, 14, 15, 16 | Input/Output signals (J1, K1, CLK1, SD1, RD1, Q1, Q̅1, J2, K2, CLK2, SD2, RD2, Q2, Q̅2) | Standard TTL-level logic terminals; pins 1–6 and 11–16 assigned per dual-flip-flop functional grouping; no shared power or ground pins. |
| 7 | GND | Signal reference and return path for all logic inputs/outputs; must be low-impedance connection to system ground plane. |
| 10 | VCC | +5V power supply input; requires local 0.1 µF ceramic decoupling capacitor placed within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent J-K flip-flops | Enables compact implementation of two-bit synchronous counters or state registers without external gating. |
| Asynchronous set/reset per section | Allows immediate initialization or forced state override independent of clock edge - critical for fault recovery in safety-critical sequencers. |
| MIL-PRF-38535 Class S qualification | Confirms compliance with screening, reliability testing, and traceability requirements for flight-critical hardware. |
| TTL-compatible input thresholds | Ensures interoperability with legacy 74LS, 74S, and 54/74-series logic without level-shifting circuitry. |
Applications
| Avionics Sequencing | Satellite Command Decoding |
|---|---|
|
Use Scenario: Synchronizing command execution windows in onboard telemetry processors where timing jitter must remain below 30 ns. IC Role / Device Role / Timing Role: Edge-triggered state latch for validated command strobes; provides metastability-hardened sampling of asynchronous uplink signals.

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 |
|---|---|---|---|
| SNJ54LS109AW | Identical electrical specs, same CFP package (W), identical pinout, and MIL-PRF-38535 Class B qualification. | Class B (not Class S) screening - lacks extended burn-in and lot acceptance test depth required for manned spacecraft. | Select SNJ54LS109AW only for cost-sensitive defense subsystems where full Class S is not mandated. |
| SN54LS109AJ | Same logic function and timing, but in 16-pin CDIP (J) package; wider body, through-hole mounting, lower thermal dissipation capability. | Not suitable for high-vibration or hermetic cavity assemblies; limited to board-level applications with conformal coating. | Choose SN54LS109AJ for ground-test equipment or non-flight prototypes where CFP handling and rework are impractical. |
Compared with SNJ54LS109AW and SN54LS109AJ, the JM38510/30109SFA delivers the highest reliability tier (Class S), strictest environmental screening, and optimal thermal/mechanical robustness for launch-critical systems - making it the sole choice when mission success depends on zero latent defects.

FAQ
What is the full device function of JM38510/30109SFA?
JM38510/30109SFA is a dual positive-edge-triggered J-K flip-flop with individual asynchronous set (SD) and reset (RD) inputs per section, delivering true (Q) and complemented (Q̅) outputs. It implements synchronous data storage and toggling functionality per IEEE Std 91-1984 logic conventions, and is fully compatible with the SN54LS109A logic diagram and truth table. The JM38510/30109SFA is not a generic logic gate or buffer - it is a sequential element with defined setup/hold timing and metastability behavior.
Is JM38510/30109SFA pin-compatible with commercial 74LS109 variants?
No - JM38510/30109SFA uses a 16-pin CFP (ceramic flatpack) package with TI drawing W, while commercial 74LS109 devices use PDIP (N), SOIC (D), or SO (NS) packages. Pin numbering and physical layout differ entirely. Direct PCB replacement is not possible without adapter hardware or board redesign. The JM38510/30109SFA pinout matches only SNJ54LS109AW and other CFP-packaged 54LS109 derivatives.
What does "NRND" status mean for JM38510/30109SFA?
"NRND" (Not Recommended for New Designs) indicates TI no longer promotes JM38510/30109SFA for newly initiated projects, though it remains in production to support existing qualified programs. Aetrix Electronics maintains active inventory and long-term sourcing agreements for JM38510/30109SFA to fulfill ongoing military, space, and nuclear infrastructure contracts where redesign is prohibited or certification costs are prohibitive.
Does JM38510/30109SFA support mixed-voltage operation or 3.3V interfaces?
No - JM38510/30109SFA is strictly a 5V TTL device. Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), output drive levels (VOH ≥ 2.7 V, VOL ≤ 0.5 V), and internal circuitry require VCC = 5V ±5%. It cannot interface directly with 3.3V or 2.5V logic families without level-shifting circuitry. The JM38510/30109SFA has no internal voltage translators, regulators, or multi-rail support.
Where can I find the official datasheet and test reports for JM38510/30109SFA?
The official JM38510/30109SFA datasheet is published by Texas Instruments under document number SN54LS109A, with military specification addenda covering Class S screening. Full qualification reports, including MIL-STD-883 test summaries and lot traceability records, are available to registered defense contractors via TI's authorized distributor portal or directly through TI's Military Products Group upon NDA execution. Aetrix Electronics provides datasheet access and assists qualified customers with documentation requests.
