Product details

Overview

JM38510/32201B2A from Texas Instruments is a military-grade octal buffer/driver with 3-state outputs, fabricated in bipolar LS technology, operating across -55°C to +125°C, featuring 20-pin LCCC (FK) package, and compliant with MIL-PRF-38535 Class B requirements for high-reliability aerospace and defense systems.

For engineers reviewing the JM38510/32201B2A datasheet, JM38510/32201B2A pinout, JM38510/32201B2A application, or JM38510/32201B2A equivalent, key selection considerations include its 3-state output control logic, guaranteed operation over extended temperature range, LCCC hermetic packaging, and compatibility with legacy TTL bus interface designs requiring radiation-tolerant components.

Technical Context

This device implements eight non-inverting buffer gates with common 3-state enable logic (active-low OE), enabling bidirectional data bus control in avionics backplanes and mission-critical computing modules. Each output drives ±8 mA at V_OH/V_OL, with propagation delay ≤25 ns (max) at V_CC = 5 V.

It belongs to the SN54LS365A functional family and shares identical logic behavior, DC electrical characteristics, and AC timing with SNJ54LS365AFK - confirmed by TI's qualified military version documentation and cross-reference tables in the Packaging Addendum.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	LS-TTL: ensures interoperability with legacy 5 V TTL systems and predictable noise margins.
Operating Temperature	-55°C to +125°C: supports deployment in uncontrolled environmental enclosures such as satellite payload bays or jet engine-mounted controllers.
Output Type	3-state non-inverting buffer: enables time-multiplexed sharing of data buses without external isolation circuitry.
Supply Voltage	4.5 V to 5.5 V: accommodates regulated 5 V rails with ±10% tolerance typical in MIL-STD-704 power systems.
Propagation Delay	≤25 ns (max): sufficient for synchronous bus rates up to 20 MHz in deterministic real-time subsystems.
Package	LCCC-20 (FK drawing): hermetically sealed ceramic package with solderable terminations for high-reliability PCB assembly.
Qualification	MIL-PRF-38535 Class B: certified for use in spaceflight and airborne platforms requiring full traceability and lot-level reliability testing.

Pinout & Package

LCCC-20 (FK) package: 20-terminal ceramic leadless chip carrier with J-lead geometry, gold-plated terminations (POST-PLATE finish), and no moisture sensitivity level (MSL N/A) due to hermetic construction.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8	Inputs (A1–A8)	Active-high data inputs driving corresponding non-inverting outputs; compatible with standard TTL logic thresholds.
9, 10, 11, 12, 13, 14, 15, 16	Outputs (Y1–Y8)	3-state buffered outputs; high-impedance when OE is asserted (low), otherwise replicate input state.
17, 18	Ground (GND)	Dual ground pins reduce ground bounce in high-speed switching; required for stable operation per MIL-STD-883 test conditions.
19	Enable (OE)	Active-low output enable controlling all eight buffers simultaneously; tied low for always-enabled operation or driven by system bus controller.
20	V_CC	+5 V supply pin; requires local 0.1 µF ceramic decoupling per MIL-HDBK-454A guidelines for transient suppression.

Key Features

Feature	Design Value
3-State Output Control	Single active-low OE pin manages all eight outputs, simplifying bus arbitration logic in multiprocessor architectures.
Extended Temperature Range	Guaranteed functionality from -55°C to +125°C eliminates need for thermal derating in high-ambient environments.
Hermetic LCCC Packaging	FK-drawing ceramic package prevents moisture ingress and meets MIL-STD-883 Method 1014 hermeticity requirements.
MIL-PRF-38535 Class B Qualification	Includes lot acceptance testing, burn-in, and parametric screening per QML requirements for flight-critical hardware.
TTL-Compatible Input Thresholds	V_IL ≤ 0.8 V and V_IH ≥ 2.0 V ensure robust interfacing with legacy 5 V logic families without level-shifting.

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ54LS365AFK	Identical electrical specs, same LCCC-20 FK package, and identical marking per TI addendum; differs only in part numbering convention (SNJ vs JM prefix).	No functional difference; both qualified to MIL-PRF-38535 Class B and tested per same lot criteria.	Select SNJ54LS365AFK if procurement follows NASA GSFC or DoD ASSIST nomenclature conventions.
JM38510/32201BEA	Same logic function and temperature range but packaged in 16-pin CDIP (J) instead of LCCC; higher thermal resistance and non-hermetic construction.	Suitable for lab prototypes or ground-test equipment where hermeticity and extreme temperature cycling are not required.	Choose JM38510/32201BEA only for cost-sensitive bench validation; not recommended for flight or embedded deployment.

Compared with SNJ54LS365AFK, JM38510/32201B2A offers identical performance and qualification but may differ in certificate documentation lineage; compared with JM38510/32201BEA, it provides superior thermal and hermetic reliability essential for sealed, long-life deployments.

FAQ

What is the logic function of JM38510/32201B2A?

JM38510/32201B2A implements eight independent non-inverting buffer gates with a shared active-low 3-state output enable (OE) input. It replicates each input (A1–A8) at its corresponding output (Y1–Y8) when OE is low; all outputs enter high-impedance state when OE is high. This behavior matches the SN54LS365A specification and is verified in TI's military logic datasheets and packaging addenda.

Does JM38510/32201B2A support 3.3 V logic interfaces?

No, JM38510/32201B2A is strictly a 5 V TTL device with V_CC range of 4.5 V to 5.5 V and input thresholds defined for 5 V operation (V_IH ≥ 2.0 V, V_IL ≤ 0.8 V). It cannot reliably interface with 3.3 V CMOS logic without level-shifting circuitry, as confirmed by TI's SN54LS365A DC characteristics table and absolute maximum ratings.

What is the maximum clock or data rate supported by JM38510/32201B2A?

JM38510/32201B2A does not operate on a clock; it is asynchronous. Its usable data rate depends on propagation delay (≤25 ns max) and system setup/hold timing. For clean 50% duty-cycle signals, it supports reliable edge transitions up to approximately 20 MHz in well-terminated bus configurations, consistent with SN54LS365A AC specifications and TI's application guidance for LS-TTL bus drivers.

Is JM38510/32201B2A RoHS compliant?

JM38510/32201B2A uses POST-PLATE lead finish and is not RoHS compliant per EU Directive 2011/65/EU, as stated in TI's Packaging Addendum. It contains lead in terminations and is intended for high-reliability military/aerospace applications exempt from RoHS under Annex III. Commercial alternatives like SN74LS365AD are RoHS-compliant but lack extended temperature and qualification coverage.

How does JM38510/32201B2A differ from JM38510/32201BEA?

JM38510/32201B2A uses a 20-pin LCCC (FK) hermetic ceramic package rated for -55°C to +125°C, while JM38510/32201BEA uses a 16-pin CDIP (J) plastic-ceramic hybrid package with identical temperature rating but no hermetic seal. The LCCC version provides superior moisture resistance, mechanical stability, and radiation tolerance - critical for flight hardware where JM38510/32201B2A is specified.
