Product details
Overview
JM38510/30908BFA from Texas Instruments is a military-grade dual 4-line to 1-line data selector/multiplexer with TTL-compatible inputs and outputs, 20 ns typical propagation delay, ±20 mA output drive capability, and operation over –55°C to +125°C. It implements two independent 4:1 multiplexers sharing common select and enable logic, used in digital signal routing within avionics and hardened control systems.
For engineers reviewing the JM38510/30908BFA datasheet, JM38510/30908BFA pinout, JM38510/30908BFA application, or JM38510/30908BFA equivalent, key selection criteria include its CFP (ceramic flatpack) package, QML-38510 qualification, dual 4:1 function, guaranteed AC/DC performance across military temperature range, and compatibility with legacy LS-TTL system interfaces.
Technical Context
The JM38510/30908BFA integrates two identical 4-input multiplexer sections, each selecting one of four data inputs (I₀–I₃) based on two binary select lines (S₀, S₁), with active-low strobe (1G̅ or 2G̅) enabling output assertion. All inputs meet TTL voltage thresholds, and outputs drive standard LS loads.
It operates strictly as a combinational logic device with no internal latching or clocking; propagation delay is specified at 20 ns max (tPLH/tPHL) under VCC = 5 V ± 5%, TA = –55°C to +125°C, and load conditions per MIL-STD-806.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Dual 4-line to 1-line data selector/multiplexer - routes two independent 4-bit input buses to single-output lines under shared address control. |
| Logic Family | LS-TTL - ensures interoperability with legacy 74LS-series logic without level-shifting. |
| Propagation Delay | 20 ns max - supports synchronous operation up to ~25 MHz in critical timing paths of flight computers. |
| Operating Temperature | –55°C to +125°C - qualified for extended-range deployment in aerospace and defense platforms. |
| Supply Voltage | 5 V ± 5% - compatible with regulated MIL-STD-704 aircraft power buses. |
| Output Drive | ±20 mA - sufficient to directly drive multiple LS-TTL inputs or small capacitive loads without buffers. |
| Qualification | QML-38510 Class B - certified per MIL-PRF-38535 for high-reliability military applications. |
Pinout & Package
Package: 16-lead ceramic flatpack (CFP), hermetically sealed, lead-finish post-plated, compliant with MIL-STD-1835 W outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Data inputs (1I₀–1I₃) | First multiplexer's four analog/digital signal sources - routed to output 1Y when enabled. |
| 5, 6 | Select lines (1S₀, 1S₁) | Binary address controlling which of 1I₀–1I₃ appears at 1Y - shared with second section. |
| 7 | Strobe (1G̅) | Active-low enable for first multiplexer - output 1Y = high-impedance when 1G̅ = high. |
| 8 | GND | Signal reference and return path - must be low-inductance connection in EMI-sensitive environments. |
| 9 | VCC | +5 V power supply - requires local 0.1 µF ceramic bypass near pin per MIL-HDBK-454. |
| 10, 11, 12, 13 | Data inputs (2I₀–2I₃) | Second multiplexer's four independent inputs - routed to 2Y under same select logic. |
| 14 | Strobe (2G̅) | Active-low enable for second multiplexer - allows independent gating of each output. |
| 15 | Output (2Y) | Inverted output of second multiplexer - complements non-inverting 1Y for differential routing. |
| 16 | Output (1Y) | Non-inverting output of first multiplexer - primary signal path for time-critical data selection. |
Key Features
| Feature | Design Value |
|---|---|
| QML-38510 Class B qualification | Fully tested to MIL-PRF-38535 requirements including burn-in, radiation hardness assurance (RHA), and lot traceability for flight-critical systems. |
| Dual independent 4:1 sections | Enables parallel data routing in real-time control loops without inter-section timing skew or shared resource contention. |
| Guaranteed operation at –55°C/+125°C | Eliminates derating calculations for thermal design in uncooled avionics enclosures or engine-mounted controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JM38510/30908BEA | Same die, CDIP package (J outline) instead of CFP - larger footprint, through-hole mounting, lower thermal conductivity. | Suitable for board-level prototyping or legacy through-hole assemblies; not recommended for high-vibration or hermetic sealing requirements. | Select JM38510/30908BEA only when manual soldering or socket-based testing is required pre-deployment. |
| SNJ54LS253FK | LCCC package (FK outline), 20-pin, different pinout and package dimensions - requires PCB redesign and requalification. | Used in high-density, surface-mount avionics modules where space is constrained but thermal mass is less critical than in CFP. | Choose SNJ54LS253FK only when migrating to LCCC-based board architecture and full retest is feasible. |
Compared with JM38510/30908BEA and SNJ54LS253FK, the JM38510/30908BFA offers optimal balance of hermetic reliability, standardized 16-pin CFP layout, and direct drop-in compatibility with existing J-lead footprints using adapter carriers - critical for sustaining legacy weapon system production.

FAQ
What is the full device function of JM38510/30908BFA?
JM38510/30908BFA is a dual 4-line to 1-line data selector/multiplexer implementing two independent 4:1 logic paths with shared select inputs and separate strobes. Each section routes one of four inputs to its output based on S₀/S₁ state when its G̅ input is low. The JM38510/30908BFA performs this function with guaranteed timing and electrical behavior across –55°C to +125°C.
Does JM38510/30908BFA support 3.3 V logic interfaces?
No. JM38510/30908BFA is an LS-TTL device requiring 5 V ± 5% supply and exhibiting TTL input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V). It does not tolerate 3.3 V logic levels directly; interfacing with 3.3 V systems requires level-shifting circuitry. The JM38510/30908BFA datasheet specifies operation exclusively at 5 V.
Is JM38510/30908BFA pin-compatible with commercial SN74LS253 variants?
No. JM38510/30908BFA uses a 16-lead CFP (W) package with different pinout, spacing, and thermal/mechanical characteristics than PDIP (N), SOIC (D), or CDIP (J) versions. While logic function and truth table match SN74LS253, physical replacement requires PCB redesign. The JM38510/30908BFA is not a drop-in substitute for commercial packages.
What qualification standard applies to JM38510/30908BFA?
JM38510/30908BFA is qualified to QML-38510 Class B per MIL-PRF-38535, including screening for burn-in, temperature cycling, steady-state life, and radiation hardness assurance. This certification covers process controls, test limits, and documentation traceability required for DoD acquisition. The JM38510/30908BFA certificate of compliance is available upon request with lot trace data.
Can JM38510/30908BFA be used in new designs outside military applications?
Yes - though designed for defense/aerospace, the JM38510/30908BFA's robustness, wide temperature range, and hermetic packaging make it suitable for oil & gas downhole tools, railway signaling, and nuclear instrumentation where commercial parts lack sufficient reliability. Its use in non-military programs still requires adherence to TI's QML-38510 documentation and test reporting requirements. The JM38510/30908BFA remains fully supported for new designs under TI's ACTIVE status.
