Product details
Overview
JM38510/32203SFA from Texas Instruments is a military-grade octal buffer/line driver with 3-state outputs, fabricated using bipolar TTL technology, operating across –55°C to +125°C, featuring 16-pin CFP (Ceramic Flatpack) package, and designed for high-reliability aerospace and defense signal routing applications.
For engineers reviewing the JM38510/32203SFA datasheet, JM38510/32203SFA pinout, JM38510/32203SFA application, or JM38510/32203SFA equivalent, key selection criteria include guaranteed operation over extended temperature range, radiation-tolerant ceramic packaging, 3-state output control timing, DC electrical specifications per MIL-STD-883, and compatibility with legacy 54LS367A logic families in avionics backplanes.
Technical Context
This device implements eight non-inverting buffer gates with independent 3-state enable inputs (1G and 2G), each controlling four outputs. It conforms to the SN54LS367A functional specification and meets MIL-PRF-38535 requirements for QML Class V manufacturing.
Input thresholds are compatible with standard TTL logic levels; output drive capability supports ±8 mA sink/source at VOH/VOL under worst-case military conditions. Propagation delay is specified at 22 ns max (tPLH/tPHL) at VCC = 5.0 V, TA = –55°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | SN54LS367A-compatible TTL - ensures interoperability with legacy military 54LS logic systems and predictable noise margins. |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883 Method 1010, enabling use in unheated spacecraft bays and jet engine-mounted electronics. |
| Supply Voltage | 4.5 V to 5.5 V - tightly regulated tolerance supports stable operation under aircraft power bus ripple and transient conditions. |
| Output Drive | ±8 mA (min) at VOH ≥ 2.4 V / VOL ≤ 0.5 V - sufficient to drive unterminated 50-Ω transmission lines or multiple TTL inputs in distributed avionics subsystems. |
| Propagation Delay | 22 ns (max) at VCC = 5.0 V - enables synchronization in sub-20-MHz digital control loops used in flight control computers. |
| Package Type | 16-pin CFP (Ceramic Flatpack, Package Drawing W) - hermetically sealed, low-outgassing, and qualified for vacuum and thermal cycling per MIL-STD-883. |
Pinout & Package
Package: 16-lead Ceramic Flatpack (CFP), Package Drawing W, hermetic ceramic-metal construction with glass-sealed leads, compliant with MIL-STD-1835.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 16, 2 | Output (Y1–Y4, Y5–Y8) | Active-high buffered outputs; high-impedance when respective G input is low - enables wired-OR bus arbitration and hot-swap isolation. |
| 3, 4, 5, 6, 10, 11, 12, 13 | Input (A1–A4, B1–B4) | Non-inverting data inputs; TTL-compatible thresholds ensure robust noise immunity in EMI-prone radar environments. |
| 7, 9 | Enable (1G, 2G) | Active-high 3-state controls; asynchronous assertion allows dynamic partitioning of data buses without clock domain crossing. |
| 8 | GND | Signal reference plane - requires dedicated low-inductance connection to minimize ground bounce in multi-buffer configurations. |
| 14 | VCC | Positive supply - must be decoupled locally with ≥100 nF ceramic + 10 µF tantalum per device to suppress switching transients. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-38535 QML Class V Qualification | Manufactured and tested to meet stringent screening, burn-in, and lot acceptance requirements for spaceflight and strategic systems. |
| Hermetic CFP Packaging | Zero moisture ingress and negligible outgassing - eliminates risk of internal condensation or corrosion during orbital thermal cycling. |
| Guaranteed AC Timing Over Full Temp Range | 22 ns max propagation delay validated at –55°C and +125°C - removes need for derating in thermal-stressed installations. |
| Input Clamp Diodes | Integrated protection against ESD and fast transients per MIL-STD-883 Method 3015.8 - reduces external TVS component count on I/O lines. |
| DC Electrical Parameters Per MIL-STD-883 | VIH(min) = 2.0 V, VIL(max) = 0.8 V, IOH = –0.4 mA, IOL = 8 mA - ensures deterministic logic behavior under voltage droop and aging. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal non-inverting buffer with 3-state outputs applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LS367AJ | Same function and DC specs; CDIP package (J) instead of CFP (W); lead finish A42 vs. A42; identical temp range. | Preferred where PCB layout uses through-hole mounting and lower-cost packaging suffices; lacks hermetic seal. | Select SNJ54LS367AJ for cost-sensitive ground-based test equipment where vacuum or long-term hermeticity is not required. |
| JM38510/32203BFA | Identical function, temp range, and CFP package; differs only in lead finish (A42 vs. A42) and status (ACTIVE vs. NRND); same marking and drawing. | No functional or application difference - represents same die in alternate production lot or revision with updated traceability. | JM38510/32203BFA is a direct form-fit-function replacement; choose based on current TI inventory availability and obsolescence planning. |
Compared with SNJ54LS367AJ, JM38510/32203SFA offers superior environmental ruggedness via hermetic CFP packaging, while JM38510/32203BFA provides identical performance with active production status-making it preferable for new designs requiring long-term supply assurance.

FAQ
What is the full logic function implemented by JM38510/32203SFA?
JM38510/32203SFA implements two groups of four non-inverting buffers (Y1–Y4 and Y5–Y8), each controlled by separate active-high 3-state enable inputs (1G and 2G). It matches the SN54LS367A truth table and is electrically and functionally identical to that military-grade octal buffer/line driver.
Is JM38510/32203SFA RoHS-compliant?
JM38510/32203SFA uses lead-based solder and finishes per MIL-STD-1835 and is exempt from RoHS under defense application allowances; its lead/ball finish is specified as A42 in TI documentation, consistent with QML Class V military procurement standards.
Does JM38510/32203SFA require external pull-up resistors on its outputs?
No. JM38510/32203SFA outputs are actively driven high or low in the enabled state and present high impedance (not floating) in the disabled state; external pull-ups are unnecessary unless interfacing with open-collector systems outside its native TTL domain.
What is the maximum clock frequency supported by JM38510/32203SFA in a data path?
JM38510/32203SFA is not a clocked device but a combinational buffer; its 22 ns max propagation delay supports reliable operation in asynchronous data paths up to approximately 20 MHz for edge-aligned timing, assuming proper trace length matching and termination.
Where can I find the official TI datasheet for JM38510/32203SFA?
The official TI datasheet for JM38510/32203SFA is published under the base part number SN54LS367A, with military specifications detailed in TI's "SN54LS367A, SN54LS368A, SN74LS367A, SN74LS368A" datasheet (SCLS122), including MIL-STD-883 test methods and QML Class V qualification data.
