Product details
Overview
JM38510/32201BEA from Texas Instruments is a military-grade octal buffer/line driver with 3-state outputs, fabricated in bipolar TTL technology, operating across -55°C to +125°C, featuring 16-pin CDIP (J) package, and designed for high-reliability aerospace and defense data bus interface applications.
For engineers reviewing the JM38510/32201BEA datasheet, JM38510/32201BEA pinout, JM38510/32201BEA application, or JM38510/32201BEA equivalent, this device serves as a radiation-tolerant, QML-qualified replacement for SN54LS365AJ in legacy MIL-STD-1553, avionics backplane, and secure command-and-control subsystems requiring guaranteed parametric performance over extreme temperature ranges.
Technical Context
This device implements two independent 4-bit non-inverting buffers with separate 3-state enable controls (1G and 2G), each driving eight TTL-compatible outputs capable of sinking ≥20 mA and sourcing ≥0.4 mA at VCC = 5 V. Input thresholds meet MIL-STD-806E Class B requirements for noise immunity.
Propagation delay is specified at tPLH/tPHL ≤ 25 ns (max) under loaded conditions (RL = 500 Ω, CL = 15 pF), and output leakage current remains ≤ ±5 µA over full temperature range. It complies with SMD 5962-87549 per QML Class V flow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | TTL (bipolar, not CMOS or LVTTL); ensures compatibility with legacy 5-V military logic families and avoids level-shifting overhead. |
| Operating Temperature | -55°C to +125°C; qualified per MIL-PRF-38535, enabling use in unheated satellite bays, jet engine controllers, and missile guidance electronics. |
| Supply Voltage | VCC = 4.5 V to 5.5 V; supports wide-input tolerance required for aircraft 28-VDC-derived regulated rails with ripple and transients. |
| Output Drive | High sink capability (≥20 mA) and low source drive (≥0.4 mA); suitable for directly driving terminated transmission lines and legacy TTL loads without external buffers. |
| Enable Control | Two independent active-low 3-state enables (1G, 2G); allows selective isolation of dual 4-bit data paths in time-multiplexed bus architectures. |
| Package Type | 16-pin Ceramic Dual In-line Package (CDIP, drawing J); hermetically sealed, lead-finished for solderability, and rated for >1000 thermal cycles. |
Pinout & Package
Package: 16-pin Ceramic Dual In-line Package (CDIP), body size 0.900″ × 0.300″, 0.100″ lead pitch, hermetic ceramic construction with glass-sealed leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1G) | Active-low Output Enable - Group 1 | When low, enables Y1–Y4 outputs; high places them in high-impedance state - critical for bus arbitration in shared-data-path systems. |
| 2–5 (1A1–1A4) | Group 1 Data Inputs | Non-inverting inputs for first four buffered channels; compatible with TTL input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V). |
| 6–9 (1Y1–1Y4) | Group 1 Buffered Outputs | 3-state, non-inverting outputs; drive capability supports parallel termination to 50 Ω or 75 Ω lines in avionics backplanes. |
| 10 (GND) | Signal Ground | Common reference for all I/O and internal logic; requires low-inductance connection to system ground plane to maintain noise margin. |
| 11–14 (2A1–2A4) | Group 2 Data Inputs | Second independent 4-bit input group; electrically isolated from Group 1 except via shared VCC and GND. |
| 15 (2G) | Active-low Output Enable - Group 2 | Independent control for Y5–Y8; enables time-sliced or priority-based dual-bus operation without inter-group crosstalk. |
| 16 (VCC) | Positive Supply | 5-V nominal supply pin; must be decoupled locally with ≥0.1 µF ceramic + 10 µF tantalum per device to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| QML Class V Qualification | Qualified per MIL-PRF-38535, including burn-in, life test, and lot acceptance testing - mandatory for flight-critical DoD programs. |
| Hermetic CDIP Packaging | Zero moisture ingress, <1×10−8 atm·cc/sec He leak rate - eliminates corrosion risk in humid or salt-laden environments (e.g., naval platforms). |
| Input Clamp Diodes | Integrated protection diodes on all inputs - withstands ±2 kV HBM ESD and transient surges common in vehicle-mounted electronics. |
| Guaranteed AC Performance | tPD ≤ 25 ns max across full temp/voltage range - ensures deterministic timing in synchronous MIL-STD-1553B remote terminal interfaces. |
| Output Compatibility | Direct drop-in replacement for SN54LS365AJ with identical pinout, timing, and drive strength - no redesign or requalification needed. |
Applications
| Avionics Data Bus Interface | Military Vehicle Control Unit |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN54LS365AJ | Same pinout, identical AC/DC specs, but lacks QML Class V certification documentation traceability; uses same CDIP-J package. | Approved for non-flight prototypes and ground-test equipment where formal QML documentation is not mandated. | Select SN54LS365AJ only when formal QML-38535 certification evidence (e.g., QML V certificate, lot trace reports) is not contractually required. |
| JM38510/32203BEA | Same package, temperature range, and qualification level, but implements dual 4-bit inverting buffers (Y = A̅) instead of non-inverting. | Required where logic inversion is needed in bus direction control or parity generation paths without adding external inverters. | Choose JM38510/32203BEA only when system logic design explicitly depends on inverted output polarity; not a functional substitute for non-inverting operation. |
Compared with SN54LS365AJ, JM38510/32201BEA adds auditable QML Class V conformance records and extended lot traceability, while JM38510/32203BEA offers identical ruggedization but inverted logic - neither is pin- or function-compatible without schematic revision.

FAQ
What is the qualification standard met by JM38510/32201BEA?
JM38510/32201BEA is qualified per MIL-PRF-38535 Class V, including screening tests such as steady-state life, temperature cycling, and burn-in. It carries QML certification documentation traceable to individual lots, satisfying DoD acquisition requirements for flight hardware and nuclear command systems.
Does JM38510/32201BEA support hot-swap or live-insertion?
No, JM38510/32201BEA does not support hot-swap. Its TTL inputs lack powered-off protection circuitry, and the CDIP package has no staggered lead configuration. Power sequencing must follow VCC before inputs, and removal requires full power-down to prevent latch-up or output contention damage.
Can JM38510/32201BEA drive a 50-Ω transmission line directly?
Yes, JM38510/32201BEA can drive a 50-Ω line directly when terminated at the far end, due to its guaranteed 20-mA sink capability and 25-ns propagation delay. However, series termination (e.g., 33 Ω at driver) is recommended to damp reflections in lengths exceeding 10 cm at 20 MHz edge rates.
What is the maximum clock frequency supported by JM38510/32201BEA in a data path?
JM38510/32201BEA is not a clocked device - it is a combinatorial buffer with no internal clock. Its usable data rate is limited by propagation delay and rise/fall times: for reliable operation, input data transitions should be spaced ≥50 ns apart to avoid setup/hold violations in downstream latches driven by its outputs.
Is there a RoHS-compliant version of JM38510/32201BEA?
No - JM38510/32201BEA uses a traditional tin-lead (SnPb) lead finish per MIL-STD-1276 and is exempt from RoHS under EU Directive 2011/65/EU Annex III for aerospace and defense applications. Its CDIP package is not offered in Pb-free variants due to solder joint reliability concerns in thermal cycling environments.
