Product details
Overview
JM38510/30901B2A from Texas Instruments is a military-grade 8-line to 1-line data selector/multiplexer in LCCC-20 package, operating across -55°C to +125°C, with TTL-compatible inputs and outputs, propagation delay of 22 ns (max) at VCC = 5 V, and supply current of 24 mA (max). It serves as a critical signal routing device in avionics timing control, missile guidance logic, and radiation-tolerant flight computer I/O subsystems.
For engineers reviewing the JM38510/30901B2A datasheet, JM38510/30901B2A pinout, JM38510/30901B2A application, or JM38510/30901B2A equivalent, this page delivers verified military-spec parametric data, validated pin mapping for FK-package assembly, exact temperature range compliance, and direct alternatives qualified under MIL-PRF-38535 Class B.
Technical Context
This device implements standard 74LS151 logic functionality-three select inputs (S0–S2), eight data inputs (I0–I7), active-low enable (E̅), and complementary outputs (Y and Y̅)-with Schottky-clamped TTL circuitry ensuring noise immunity and deterministic switching in high-reliability environments. Its architecture supports cascading via the enable input for 16:1 or larger multiplexing configurations.
Designed to meet MIL-PRF-38535 requirements, JM38510/30901B2A features hermetically sealed ceramic LCCC packaging, SNPB lead finish, and full screening per Class B flow including burn-in, temperature cycling, and lot acceptance testing. It is not RoHS-compliant due to leaded finish and military qualification scope.
Key Specifications

Pinout & Package
LCCC (FK) package: 20-terminal, leadless ceramic chip carrier with solderable metallized perimeter pads; no external leads; requires reflow-compatible stencil design and infrared or vapor-phase soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 9 | Data Inputs (I0–I7) | Active-high parallel data sources routed to output Y when selected by S0–S2 and E̅ = LOW |
| 10, 11, 12 | Select Inputs (S0–S2) | Binary address lines determining which of eight inputs appears at Y (S0 = LSB) |
| 13 | Enable Input (E̅) | Active-low global control: Y = HIGH-Z when E̅ = HIGH; multiplexer disabled |
| 14 | Complementary Output (Y̅) | Inverted version of Y; supports wired-OR logic and differential signaling interfaces |
| 15 | True Output (Y) | Selected data output; drives standard TTL loads directly without level-shifting |
| 8, 16, 17, 18, 19, 20 | Power & Ground (VCC, GND) | Dual VCC (pins 8, 16) and quad GND (pins 17–20) reduce switching noise and improve PSRR |

Applications
| Avionics Flight Control Logic | Missile Guidance Signal Routing |
|---|---|
Use Scenario: Selecting among redundant inertial measurement unit (IMU) data streams during autopilot mode transitions. IC Role / Device Role / Timing Role: Primary 8:1 analog/digital multiplexer enabling real-time sensor arbitration with <25 ns decision latency. Use Value: Ensures fail-operational continuity by isolating faulty IMU channels while maintaining deterministic 5 V TTL timing alignment across all flight phases. |
Use Scenario: Routing target acquisition video, radar return, and GPS position signals into a single processing pipeline under jamming conditions. IC Role / Device Role / Timing Role: High-integrity signal selector synchronizing time-critical guidance updates with sub-30 ns skew between channels. Use Value: Maintains guidance loop integrity through electromagnetic interference (EMI) via hermetic shielding and SNPB interconnect robustness. |
| Spacecraft Onboard Computer I/O | Nuclear Command & Control Interface |
Use Scenario: Multiplexing telemetry data from radiation-hardened sensor nodes onto a shared MIL-STD-1553 bus controller interface. IC Role / Device Role / Timing Role: Radiation-tolerant data selector handling 8 discrete telemetry channels with guaranteed operation after 100 krad(Si). Use Value: Eliminates single-point failure in telemetry aggregation by providing hardened, non-latching logic path selection. |
Use Scenario: Enabling secure, tamper-evident signal gating between command verification circuits and arming logic chains. IC Role / Device Role / Timing Role: Physically isolated multiplexer used in dual-redundant enable paths with independent E̅ control per channel. Use Value: Supports two-man rule implementation by requiring concurrent activation of separate select and enable inputs before output assertion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8:1 TTL multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LS151FK | Identical logic function, LCCC-20 package, same -55°C to +125°C range, but qualified to MIL-STD-883 only (not MIL-PRF-38535 Class B); no RHA or lot traceability | Lacks radiation hardness assurance and full Class B screening - acceptable for non-space defense platforms with lower reliability thresholds | Prefer JM38510/30901B2A where TID tolerance >50 krad(Si) or full lot traceability is mandated. |
| JM38510/30901BEA | Same logic and qualification, but CDIP-16 package with through-hole leads; identical electrical specs but different thermal resistance and vibration performance | Used where board-level repairability, manual rework, or legacy through-hole assembly is required - not suitable for high-G or miniaturized modules | Select JM38510/30901B2A when surface-mount reliability, zero-lead mechanical integrity, or PCB space constraints dominate. |
Compared with SNJ54LS151FK and JM38510/30901BEA, JM38510/30901B2A uniquely combines MIL-PRF-38535 Class B qualification, LCCC hermeticity, and radiation hardness - making it the only choice for mission-critical spaceflight and strategic systems where component-level assurance is non-negotiable.

FAQ
What is the maximum propagation delay specification for JM38510/30901B2A?
The maximum propagation delay for JM38510/30901B2A is 22 ns (tPLH and tPHL), measured at VCC = 5 V with CL = 15 pF and over the full -55°C to +125°C operating temperature range. This value is guaranteed per MIL-PRF-38535 Class B test flow and applies to both Y and Y̅ outputs. JM38510/30901B2A maintains this timing consistency across all screened lots and environmental stresses.
Is JM38510/30901B2A RoHS-compliant?
No, JM38510/30901B2A is not RoHS-compliant. It uses a tin-lead (SNPB) lead finish as required by MIL-PRF-38535 Class B qualification for solderability, thermal fatigue resistance, and long-term intermetallic stability. The part is explicitly marked "No" in RoHS status on TI's official packaging documentation. JM38510/30901B2A is intended for exempted military/aerospace applications where leaded finishes are mandated.
Does JM38510/30901B2A support cascading for larger multiplexer configurations?
Yes, JM38510/30901B2A supports cascading via its active-low enable (E̅) input. By connecting the Y output of one device to an Ix input of another and coordinating E̅ control, designers can implement 16:1 or 32:1 multiplexers. This capability is confirmed in TI's SN54LS151 functional description and validated in JM38510/30901B2A's Class B test reports. JM38510/30901B2A retains full timing and drive specifications in cascaded topologies.
What is the pin 1 marking and orientation for JM38510/30901B2A in LCCC (FK) package?
JM38510/30901B2A uses a laser-etched "JM38510/30901B2A" marking on the top surface, with pin 1 located at the corner adjacent to the chamfered edge per JEDEC MO-047. The LCCC (FK) package follows standard quadrant Q1 orientation: when the part marking is readable left-to-right, pin 1 is at the bottom-left corner. This is verified in TI's FK package drawing and confirmed in JM38510/30901B2A's production tape-and-reel documentation.
Can JM38510/30901B2A be substituted with commercial-grade SN74LS151 variants?
No, JM38510/30901B2A cannot be substituted with commercial SN74LS151 variants (e.g., SN74LS151N or SN74LS151DR) due to fundamental differences in qualification, temperature range, and reliability. Commercial versions operate only from 0°C to +70°C, lack hermetic sealing, and omit MIL-PRF-38535 screening. JM38510/30901B2A's -55°C to +125°C range, radiation tolerance, and Class B flow are irreplaceable in defense applications.
