Product details
Overview
JM38510/30102SDA from Texas Instruments is a military-grade dual D-type positive-edge-triggered flip-flop in ceramic flatpack (CFP) packaging, operating across –55°C to +125°C, with 14-pin configuration, TTL-compatible input thresholds, and guaranteed propagation delay ≤30 ns at VCC = 5 V. It serves as a synchronous storage element in radiation-tolerant avionics timing and control logic.
For engineers reviewing the JM38510/30102SDA datasheet, JM38510/30102SDA pinout, JM38510/30102SDA application, or JM38510/30102SDA equivalent, this device supports high-reliability digital state retention in deterministic real-time systems where extended temperature range and hermetic sealing are mandatory.
Technical Context
This device implements two independent D-type latches with complementary Q and Q̅ outputs, each triggered on the rising edge of the clock signal. It features TTL-level compatible inputs, guaranteed noise immunity of ≥0.4 V under worst-case conditions, and operates with supply voltage fixed at 5 V ±5%.
No internal reset or preset functionality is provided; asynchronous control requires external gating. The CFP package ensures hermeticity and thermal stability, meeting MIL-STD-883 requirements for mechanical shock, vibration, and humidity resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | LS-TTL - ensures compatibility with legacy 74LS-series interface logic and predictable fanout loading. |
| Clock Edge Sensitivity | Positive-edge-triggered - synchronizes state capture precisely at rising transitions, enabling deterministic sampling in hard-real-time control loops. |
| Propagation Delay (tPLH/tPHL) | ≤30 ns max at VCC = 5 V - supports clock frequencies up to ~15 MHz in non-critical timing paths with margin. |
| Operating Temperature | –55°C to +125°C - validated for deployment in jet engine controllers, missile guidance electronics, and space-qualified subsystems. |
| Supply Voltage | 5 V ±5% - requires tightly regulated rail; no built-in voltage regulation or brownout detection. |
| Package Type | CFP (Ceramic Flatpack, Package Drawing W) - hermetically sealed, lead-finished with Call TI specification, MSL not applicable. |
Pinout & Package
Ceramic Flatpack (CFP), 14-terminal, side-brazed, hermetically sealed package per MIL-STD-1835 GDIP1-T14; dimensions per TI drawing W, body height ≤5.08 mm, lead finish unspecified beyond "Call TI".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | Data and output terminals | Two independent D-type flip-flops: Pins 1(D1), 2(Q1), 3(CP1), 4(Q̅1), 5(D2), 6(Q2), 7(Q̅2), 8(GND), 9(CP2), 10(1CLR), 11(VCC), 12(2CLR), 13(1PR), 14(2PR) - note: PR/CLR are active-low asynchronous inputs per flip-flop. |
| 3, 9 | CLK inputs | Rising-edge sensitive clock inputs for Flip-Flop 1 (Pin 3) and Flip-Flop 2 (Pin 9); no internal synchronization between clocks. |
| 8 | GND | Signal reference plane; must be low-impedance connection to minimize ground bounce in high-speed switching. |
| 11 | VCC | +5 V power supply; decoupling capacitor required within 10 mm of pin to suppress transient current spikes. |
| 10, 12 | CLR inputs | Active-low asynchronous clear for FF1 (Pin 10) and FF2 (Pin 12); forces Q = 0, Q̅ = 1 regardless of clock or D state. |
| 13, 14 | PR inputs | Active-low asynchronous preset for FF1 (Pin 13) and FF2 (Pin 14); forces Q = 1, Q̅ = 0 independently of clock or D state. |
Key Features
| Feature | Design Value |
|---|---|
| QML-38510 Qualified | Qualified to MIL-PRF-38535 Class B, meeting screening and test requirements for high-reliability defense/aerospace applications. |
| Hermetic CFP Packaging | Prevents moisture ingress and corrosion in humid, salt-laden, or vacuum environments; enables long-term reliability without conformal coating. |
| Asynchronous Set/Clear per FF | Independent PR/CLR pins allow immediate state override without waiting for clock edge - critical for fault recovery and initialization sequences. |
| TTL-Compatible Input Thresholds | VIL ≤ 0.8 V, VIH ≥ 2.0 V - ensures interoperability with legacy 74LS, 74S, and 54-series logic families without level-shifting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LS74AW | Identical logic function, same CFP package (W), identical pinout and electrical specs; differs only in part numbering convention (SNJ vs JM prefix). | No functional difference; both meet MIL-PRF-38535 Class B and operate over –55°C to +125°C. | Select SNJ54LS74AW if procurement documentation requires standard SNJ nomenclature or if sourcing via legacy DoD contracts referencing that designation. |
| SN54LS74AJ | Same logic function and temperature range but in ceramic DIP (J) package; propagation delay identical, but package lacks side-brazed hermeticity of CFP. | Less suitable for high-vibration or high-humidity environments due to non-hermetic DIP lid seal; lower mechanical robustness than CFP. | Choose SN54LS74AJ only when board layout constraints prohibit CFP footprint or when cost-sensitive non-mission-critical prototypes require faster availability. |
Compared with SNJ54LS74AW, JM38510/30102SDA offers identical performance and qualification but reflects updated 38510 revision coding; versus SN54LS74AJ, it delivers superior environmental ruggedness via CFP hermeticity-critical where mechanical stress or condensation risk exists.

FAQ
What is the qualified reliability standard for JM38510/30102SDA?
JM38510/30102SDA is qualified to MIL-PRF-38535 Class B, including full screening per Method 5005, burn-in, and lot acceptance testing. It meets all requirements for QML-38510 certification, with documentation traceable to individual wafer lots and assembly batches. This qualification applies specifically to the JM38510/30102SDA variant in CFP packaging, not generic 74LS74 derivatives.
Does JM38510/30102SDA support 3.3-V logic interfaces?
No, JM38510/30102SDA is strictly a 5-V TTL device with VCC = 5 V ±5% and input thresholds defined for LS-TTL levels (VIL ≤ 0.8 V, VIH ≥ 2.0 V). It cannot reliably interface with 3.3-V CMOS logic without level translation, as its inputs do not tolerate 3.3-V signaling as valid high-level inputs under worst-case conditions.
Are the preset and clear inputs on JM38510/30102SDA synchronous or asynchronous?
The preset (PR) and clear (CLR) inputs on JM38510/30102SDA are asynchronous and active-low. They force the corresponding flip-flop's Q output to 1 or 0 immediately, regardless of clock state or D input value. This behavior is confirmed in the SDLS119 datasheet and applies identically to both flip-flop sections within JM38510/30102SDA.
What is the maximum clock frequency supported by JM38510/30102SDA?
JM38510/30102SDA does not specify a maximum clock frequency in its datasheet; instead, it guarantees tPLH/tPHL ≤30 ns and minimum pulse width requirements. Based on these, reliable operation is ensured up to approximately 15 MHz in well-designed layouts with controlled trace impedance and proper decoupling - though actual usable frequency depends on system-level timing margins and board parasitics.
Can JM38510/30102SDA be used as a drop-in replacement for commercial SN74LS74A devices?
No, JM38510/30102SDA is not a drop-in replacement for SN74LS74A. While functionally identical, it uses CFP packaging (14-pin, flat leads) versus SOIC/PDIP footprints, requires different PCB land patterns and reflow profiles, and operates over –55°C to +125°C - necessitating full mechanical and thermal revalidation. Its qualification scope also differs fundamentally.
