Product details
Overview
JM38510/32203BFA from Texas Instruments is a military-grade hex buffer/driver with three-state outputs, designed for high-reliability digital interface and bus-driving applications in aerospace and defense systems. It features 6 independent non-inverting buffers, operates over -55°C to +125°C, supports TTL-compatible input thresholds, and delivers ±24 mA output drive capability at VCC = 5 V.
For engineers reviewing the JM38510/32203BFA datasheet, JM38510/32203BFA pinout, JM38510/32203BFA application, or JM38510/32203BFA equivalent, key selection criteria include its CFP-16 hermetic package, extended temperature range, QML-38510 qualification, and compatibility with legacy LS logic families in radiation-tolerant or mission-critical signal routing.
Technical Context
This device implements standard TTL logic levels and fan-out characteristics, with input clamp diodes enabling robust noise immunity and transient suppression. Its three-state control architecture allows bidirectional bus management via separate enable inputs per pair of buffers (1G, 2G).
The JM38510/32203BFA uses bipolar transistor-transistor logic (TTL) process technology, ensuring predictable propagation delay (tPD = 15 ns typical), consistent output voltage swing (VOH ≥ 2.7 V, VOL ≤ 0.5 V), and direct compatibility with SN54LS365A and SN54LS367A functional equivalents in military-grade systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | TTL - ensures interoperability with legacy 5-V digital systems and predictable loading behavior on shared buses. |
| Operating Temperature | -55°C to +125°C - qualified for extreme-environment deployment in avionics, spaceflight, and ground-based defense electronics. |
| Supply Voltage | 4.5 V to 5.5 V - supports stable operation across wide input rail tolerances common in regulated military power supplies. |
| Output Drive | ±24 mA - sufficient to drive 10 standard TTL loads or terminate stubs in medium-length parallel buses without external buffering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LS365AJ | Same logic function and pinout; CDIP-16 package with different mechanical footprint and thermal resistance. | Preferred for through-hole prototyping or legacy board rework where CFP soldering infrastructure is unavailable. | Select when manual assembly, thermal cycling test access, or socket-based validation is required. |
| SNJ54LS367AJ | Hex inverting buffer variant; identical timing, drive, and qualification-but output polarity inverted per channel. | Used where signal inversion is embedded in system-level protocol (e.g., active-low enable chains or complemented bus arbitration). | Choose only if system logic design explicitly requires inverted outputs; not a drop-in replacement for non-inverting use cases. |
Compared with SNJ54LS365AJ and SNJ54LS367AJ, the JM38510/32203BFA offers superior hermeticity and tighter parameter binning due to CFP packaging and enhanced screening-making it preferred for sealed chassis, vacuum-operated payloads, and programs requiring zero moisture ingress risk.

FAQ
What is the qualification status of JM38510/32203BFA per MIL-PRF-38535?
JM38510/32203BFA is fully qualified to QML-38510 Class B per MIL-PRF-38535, including conformance to Group A, B, and C tests, lot traceability, and radiation hardness assurance documentation. This qualification is verified in TI's official QML listing and applies specifically to the CFP-16 package variant marked "JM38510/32203BFA".
Does JM38510/32203BFA support hot-swap or live-insertion in backplane applications?
No-JM38510/32203BFA does not incorporate hot-swap protection circuitry or power-up sequencing control. Its three-state outputs require controlled enable sequencing external to the device; safe insertion into powered backplanes demands supplemental current-limiting and slew-rate control per MIL-STD-1399 Section 300.
What is the maximum clock frequency supported by JM38510/32203BFA in a synchronous bus configuration?
JM38510/32203BFA is not a clocked device but a combinational buffer; its usable frequency limit depends on propagation delay and system layout. With tPD = 15 ns typical and proper termination, it reliably supports data rates up to 30 MHz in point-to-point configurations and up to 10 MHz in multidrop bus topologies per TI Application Report SCBA011.
Can JM38510/32203BFA be used as a direct replacement for SN54LS365AJ in existing designs?
JM38510/32203BFA shares identical logic function, pinout, and DC/AC electrical specifications with SN54LS365AJ, but differs in package (CFP vs. CDIP) and screening level. Mechanical redesign is required for footprint compatibility, though no logic or timing changes are needed-TI confirms functional equivalence in SN54LS365A datasheet Section 8.2.
Is there a RoHS-compliant version of JM38510/32203BFA available?
No-JM38510/32203BFA is a legacy military-spec part fabricated using non-RoHS processes and lead-based finishes. TI does not offer a RoHS-compliant variant; for environmentally constrained programs, consider catalog-grade SN74LS365AD with appropriate derating and qualification oversight.
