Product details
Overview
JM38510/30902BEA from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer with independent enable controls, TTL-compatible inputs and outputs, propagation delay of 15 ns typical at VCC = 5 V, fan-out of 10 LSTTL loads, and operating temperature range of –55°C to +125°C. It is used in military-grade digital logic systems for signal routing in avionics data buses and hardened test instrumentation.
For engineers reviewing the JM38510/30902BEA datasheet, JM38510/30902BEA pinout, JM38510/30902BEA application, or JM38510/30902BEA equivalent, key selection criteria include military temperature range compliance, CDIP-16 hermetic packaging, SN54LS153 functional equivalence, and compatibility with legacy 5-V TTL logic families in high-reliability embedded control.
Technical Context
The JM38510/30902BEA implements two independent 4:1 multiplexers sharing common select lines (S0, S1) but with separate strobe inputs (1G̅, 2G̅), enabling asynchronous channel gating. Each section routes one of four data inputs (1A0–1A3 or 2A0–2A3) to its output (1Y or 2Y) based on binary select code.
It uses bipolar Schottky-clamped TTL circuitry with guaranteed noise margins of 0.4 V (low) and 0.4 V (high), supports wired-AND expansion via open-collector-compatible outputs when externally pulled up, and meets MIL-PRF-38535 Class B requirements for screening and reliability testing.

Pinout & Package
Package: CDIP (J), 16-pin ceramic dual in-line, hermetically sealed, SNPB lead finish, RoHS-exempt, MSL N/A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A0 | Data input 0 for first multiplexer - connects to source signal requiring selection under S0/S1 control. |
| 2 | 1A1 | Data input 1 for first multiplexer - provides second selectable input path for channel A. |
| 3 | 1A2 | Data input 2 for first multiplexer - enables third discrete signal routing option in 4:1 configuration. |
| 4 | 1A3 | Data input 3 for first multiplexer - completes full 4-input set for primary mux section. |
| 5 | 1G̅ | Active-low enable for first multiplexer - asserts low to activate output 1Y; high forces 1Y to high-impedance state. |
| 6 | 2A0 | Data input 0 for second multiplexer - independent data path synchronized to same S0/S1 but gated by 2G̅. |
| 7 | 2A1 | Data input 1 for second multiplexer - parallel input structure supporting dual-channel signal switching. |
| 8 | GND | Ground reference - common return for all internal logic and I/O circuits; must be low-inductance connection. |
| 9 | 2A2 | Data input 2 for second multiplexer - enables simultaneous 4:1 routing on second channel. |
| 10 | 2A3 | Data input 3 for second multiplexer - completes second independent 4-input set. |
| 11 | 2G̅ | Active-low enable for second multiplexer - independent gating control allows time-multiplexed or conditional routing. |
| 12 | 1Y | Output of first multiplexer - driven low or high depending on selected input and enable status; TTL-compatible voltage levels. |
| 13 | 2Y | Output of second multiplexer - electrically isolated from 1Y; supports concurrent dual-output operation. |
| 14 | VCC | Positive supply - requires stable 5 V ±5% with local bypass capacitance to suppress switching noise. |
| 15 | S0 | Select line 0 - least-significant bit of 2-bit address determining which of four inputs is routed to output. |
| 16 | S1 | Select line 1 - most-significant bit of 2-bit address; together with S0, defines active input index (0–3). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 multiplexers | Enables two parallel signal-selection paths using shared address lines - reduces board space and simplifies control logic in telemetry interfaces. |
| Separate active-low strobes (1G̅, 2G̅) | Allows selective activation or disabling of each multiplexer without affecting the other - critical for fault-isolated subsystems in flight computers. |
| Guaranteed 15 ns propagation delay | Ensures deterministic timing behavior in synchronous bus arbitration and real-time sensor data switching applications. |
| MIL-PRF-38535 Class B qualification | Includes rigorous screening (burn-in, temperature cycling, hermeticity tests) - required for deployment in defense platforms with 15+ year service life. |
| TTL-compatible input thresholds | Accepts standard 0.8 V / 2.0 V logic thresholds - eliminates level-shifting in mixed-generation avionics backplanes. |

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 |
|---|---|---|---|
| SNJ54LS153J | Identical electrical specs and pinout; differs only in part marking and QML certification documentation traceability. | No functional difference; both meet MIL-PRF-38535 Class B, but SNJ54LS153J has alternate lot trace format per TI internal revision control. | Select SNJ54LS153J if procurement requires TI's current QML-38535 certificate version or specific lot pedigree reporting. |
| SN54LS153J | Same die, CDIP-16 package, and performance; differs in screening level - qualified to MIL-STD-883 Method 3015.8 (not full Class B). | Limited to non-safety-critical ground support equipment where full Class B burn-in and radiation assurance are not mandated. | Choose SN54LS153J for cost-sensitive developmental platforms where full flight qualification is deferred to later stages. |
Compared with SNJ54LS153J and SN54LS153J, the JM38510/30902BEA provides identical functionality and timing but carries a distinct DSCC drawing number and is tracked under U.S. Defense Logistics Agency (DLA) standards for long-term obsolescence management and counterfeit mitigation.

FAQ
What is the operating temperature range specified for the JM38510/30902BEA?
The JM38510/30902BEA is rated for continuous operation from –55°C to +125°C, validated per MIL-STD-883 Method 1010 and qualified to MIL-PRF-38535 Class B. This range is guaranteed across all electrical parameters in the datasheet, including propagation delay and noise margins, making it suitable for deployment in uncontrolled external avionics bays and engine-mounted control units where thermal extremes occur.
Is the JM38510/30902BEA pin-compatible with commercial SN74LS153 devices?
No - the JM38510/30902BEA uses a CDIP-16 package with SNPB leads and military-grade screening, whereas commercial SN74LS153 variants (e.g., SN74LS153N) use PDIP-16 with RoHS-compliant NiPdAu plating and operate only from 0°C to +70°C. Pin numbering and function are identical, but PCB layout must accommodate different thermal and mechanical mounting requirements, and no drop-in replacement is assured without validation of solder process and long-term reliability.
Does the JM38510/30902BEA support wired-AND logic configurations?
Yes - the outputs of the JM38510/30902BEA are standard TTL totem-pole drivers, but they can be externally wired-ANDed by connecting 1Y and 2Y to a common pull-up resistor and diode-isolating inputs, provided fan-out and voltage margins are recalculated. The device itself does not feature open-collector outputs, so external diodes or logic gates are required to implement true wired-AND functionality in bus arbitration schemes.
What is the maximum clock frequency supported by the JM38510/30902BEA when used in a synchronous multiplexing application?
The JM38510/30902BEA does not have a defined "clock frequency" since it is combinational logic, but its 15 ns typical propagation delay supports reliable operation in systems with minimum pulse widths ≥30 ns. When used with edge-triggered controllers, it enables effective signal routing at sustained data rates up to ~30 MHz, assuming setup/hold times of adjacent flip-flops are met and select lines are stabilized before strobe assertion.
How does the JM38510/30902BEA differ from the SNJ54LS153J in terms of qualification and traceability?
The JM38510/30902BEA is assigned a DSCC drawing number and tracked under U.S. Defense Logistics Agency standards, with full lot-level traceability to raw wafer lots and assembly batches per MIL-STD-883. The SNJ54LS153J shares identical silicon and packaging but follows TI's internal QML-38535 certification path with alternate documentation formatting and revision control - both meet Class B, but JM38510/30902BEA is preferred for DLA-managed programs requiring formal drawing-number compliance.
