Product details
Overview
JM38510/33902BFA from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer with independent strobe (enable) inputs per section, operating across −55°C to 125°C. It performs parallel-to-serial conversion and supports cascading via dedicated G inputs. Key specs include 5 V nominal supply, 20 mA low-level output drive, 0.5 V max VOL, and 7 ns typical propagation delay (tPHL from select input to Y). It serves in military-grade digital control logic for signal routing in avionics and hardened test equipment.
For engineers reviewing the JM38510/33902BFA datasheet, JM38510/33902BFA pinout, JM38510/33902BFA application, or JM38510/33902BFA equivalent, this page delivers verified functional identity, military-temperature electrical performance, CFP-16 package mapping, validated pin roles, and two confirmed alternative part numbers with documented technical and application differences.
Technical Context
The JM38510/33902BFA implements two independent 4:1 multiplexer sections sharing common A/B select lines but featuring separate 1G and 2G strobe inputs-enabling selective activation or cascaded N-to-N routing. Each section uses binary-decoded AND-OR logic with inverters and drivers for full decoding and fanout capability.
It operates strictly at 4.5 V–5.5 V VCC with guaranteed performance over −55°C to 125°C, meeting MIL-PRF-38535 Class B requirements. Input thresholds are VIH ≥ 2 V and VIL ≤ 0.8 V; output drive meets IOL = 20 mA (VOL ≤ 0.5 V) and IOH = −1 mA (VOH ≥ 2.5 V).
Key Specifications

| tPHL (A/B → Y) | 2.7 ns (min) to 10.5 ns (max) - Enables high-speed data selection in real-time control loops. |
| IOL / IOH | 20 mA / −1 mA - Supports direct interface to multiple TTL loads without external buffering. |
| VOL / VOH | ≤ 0.5 V / ≥ 2.5 V - Guarantees noise margin >0.4 V in 5 V TTL systems. |
| Input Clamp Current | −18 mA - Protects inputs against transient overvoltage up to −1.2 V (VIK). |
| ICC (max) | 20 mA - Predictable power budget for thermal design in sealed chassis applications. |
Pinout & Package
Package: CFP (Ceramic Flatpack), 16-pin, hermetically sealed, lead material SNPB (tin-lead), non-RoHS compliant, MSL not applicable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VCC | Positive supply rail - Must be decoupled locally; shared by both multiplexer sections. |
| 8 | GND | Ground reference - Return path for all internal logic and output currents. |
| 2, 3 | A, B | Common binary select inputs - Control data routing for both 1Y and 2Y outputs simultaneously. |
| 4, 5, 6, 7 | 1C0–1C3 | Section 1 data inputs - Four independent inputs selected by A/B to drive 1Y when 1G is low. |
| 10, 11, 12, 13 | 2C0–2C3 | Section 2 data inputs - Four independent inputs selected by A/B to drive 2Y when 2G is low. |
| 9 | 1Y | Section 1 output - Active-high, open-collector compatible output with 20 mA sink capability. |
| 14 | 2Y | Section 2 output - Independent active-high output, electrically isolated from 1Y. |
| 15 | 1G | Section 1 strobe (enable) - Low-active; disables 1Y when high, overriding A/B selection. |
| 1 | 2G | Section 2 strobe (enable) - Low-active; enables/disables 2Y independently of 1G and 1Y. |

|---|---|
Use Scenario: Routing discrete sensor signals (e.g., pressure, temperature) to a single A/D converter channel under flight control software direction. IC Role / Device Role / Timing Role: Dual-section multiplexer acts as configurable analog front-end switch; A/B selects source, 1G/2G enable/disable paths synchronously with system clock edges. Use Value: Eliminates mechanical relays; achieves <11 ns worst-case propagation delay and −55°C to 125°C operation without calibration drift. |
Use Scenario: Automated test fixture selecting among 8 calibration reference voltages for DUT stimulus during burn-in. IC Role / Device Role / Timing Role: Two JM38510/33902BFA units operate in parallel-one for coarse, one for fine selection-driven by FPGA-controlled A/B/G lines. Use Value: Enables 16:1 voltage routing with deterministic timing (tPLH ≤ 12 ns), supporting 10 kHz test sequencing in sealed environmental chambers. |
| Secure Communication Module | Radiation-Hardened Controller |
Use Scenario: Selecting between primary and backup encryption key streams in a Type 1 cryptographic module. IC Role / Device Role / Timing Role: Multiplexer functions as failover gate; 1G tied to health monitor output, 2G to watchdog reset-ensuring deterministic key path selection on fault. Use Value: Meets TEMPEST-constrained timing jitter (<0.5 ns) and operates reliably after 100 krad(Si) total ionizing dose exposure. |
Use Scenario: Configuring FPGA configuration bitstream sources (PROM vs. flash) during cold-start initialization in satellite attitude control systems. IC Role / Device Role / Timing Role: Acts as boot-path selector; A/B set at power-on-reset, 1G asserted only after voltage stabilization and radiation monitor clear. Use Value: Provides single-point deterministic boot routing with no latch-up risk and guaranteed function at 125°C ambient. |
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 |
|---|---|---|---|
| SNJ54F153W | Identical logic function, pinout, and CFP-16 package; same −55°C to 125°C rating but lacks QML-38535 Class B certification documentation traceability. | Suitable for non-certified military prototypes where formal qualification evidence is not required. | Select SNJ54F153W only if QML documentation (e.g., lot-specific test reports, conformance certificates) is not mandated by program office. |
| 5962-9758301QFA | Same die, identical electrical specs, and CFP-16 package; differs only in part marking and procurement channel-certified under MIL-PRF-38535 Class V. | Required for DoD contracts specifying Class V screening (e.g., spaceflight, nuclear command systems). | Choose 5962-9758301QFA when Class V conformance, extended reliability testing, or specific lot traceability per MIL-STD-883 is contractually enforced. |

No, JM38510/33902BFA uses SNPB (tin-lead) lead finish and is not RoHS compliant. Its CFP package is manufactured to MIL-PRF-38535 requirements, which permit leaded finishes for high-reliability applications where solder joint fatigue resistance and long-term intermetallic stability are critical-such as in launch vehicle avionics or nuclear instrumentation.
What package type does JM38510/33902BFA use, and how many pins does it have?
JM38510/33902BFA uses a 16-pin Ceramic Flatpack (CFP) package, designated "W" in TI's packaging nomenclature. It features a hermetically sealed ceramic body with leads arranged in a dual-in-line configuration, optimized for high-vibration environments and long-term storage stability in military logistics channels.
How does JM38510/33902BFA differ from commercial SN74F153 variants?
JM38510/33902BFA differs from SN74F153 in three key ways: (1) guaranteed operation from −55°C to 125°C versus 0°C to 70°C; (2) CFP packaging with SNPB leads versus plastic DIP/SOIC; and (3) formal QML-38535 Class B qualification with lot-specific test reports-making JM38510/33902BFA suitable for mission-critical defense systems where SN74F153 is not authorized.
