Product details
Overview
JM38510/30103B2A from Texas Instruments is a military-grade dual J-K negative-edge-triggered flip-flop with complementary outputs, 20-pin LCCC package, -55°C to +125°C operating temperature range, and POST-PLATE lead finish. It serves as a synchronous storage element in radiation-tolerant avionics timing and control circuits.
For engineers reviewing the JM38510/30103B2A datasheet, JM38510/30103B2A pinout, JM38510/30103B2A application, or JM38510/30103B2A equivalent, key selection criteria include QML-38510 Class B qualification, LCCC-20 hermetic packaging, dual independent J-K functionality, negative-edge clocking, and full military temperature range support.
Technical Context
This device implements two identical, independent J-K flip-flops with individual Set (SD), Reset (RD), J, K, and Clock (CP) inputs plus true and complemented outputs (Q, Q̅). Each section operates synchronously on the falling edge of CP.
It conforms to MIL-PRF-38535 requirements for QML Class B flow, supports direct DC-coupled interstage connection without level-shifting, and maintains functional integrity under single-event latchup (SEL)-hardened design practices typical of space-grade logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual J-K flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LS112AFK | Same LCCC-20 package, identical pinout, but rated for -55°C to +125°C with QML-38510 Class B compliance | Identical functional scope; differs only in device marking and lot trace methodology | Select SNJ54LS112AFK when cross-reference to legacy 54LS112 nomenclature is required in documentation or BOMs |
| JM38510/30103BEA | CDIP-16 package (J drawing), same electrical specs, but non-hermetic plastic package with lower moisture resistance | Suitable for ground-based test benches or non-vacuum environments where cost and hand-solderability are prioritized | Choose JM38510/30103BEA for lab validation or benchtop integration where hermeticity is not mandated |
Compared with SNJ54LS112AFK and JM38510/30103BEA, the JM38510/30103B2A provides identical logic function and QML Class B qualification but uniquely combines LCCC-20 mechanical robustness with TI's post-plated termination system for enhanced wire-bond reliability in vibration-prone platforms.

FAQ
What is the full device type and logic function of JM38510/30103B2A?
JM38510/30103B2A is a QML-38510 Class B qualified dual J-K negative-edge-triggered flip-flop with complementary outputs and asynchronous set/reset. It performs synchronous data storage and state sequencing in high-integrity digital systems. The JM38510/30103B2A implements two independent J-K sections, each with J, K, CP, SD, RD, Q, and Q̅ terminals, and operates across -55°C to +125°C.
Does JM38510/30103B2A support positive-edge clocking?
No, JM38510/30103B2A is strictly negative-edge-triggered - its outputs change only on the falling edge of the clock input (CP). This behavior is fixed by internal circuit architecture and cannot be modified via external biasing or configuration. Designers must align upstream clock sources accordingly; the JM38510/30103B2A does not offer selectable edge sensitivity.
Is JM38510/30103B2A RoHS-compliant?
JM38510/30103B2A uses a POST-PLATE lead finish per MIL-G-45204 and is exempt from RoHS Directive 2011/65/EU Annex III due to its QML-38510 Class B military qualification. It contains lead in the metallization system, which is permitted under EU RoHS exemption 7a for high-reliability applications. The JM38510/30103B2A is not classified as "Green" or "RoHS Compliant" per TI's eco-plan definitions.
What is the maximum clock frequency specification for JM38510/30103B2A?
The maximum clock frequency for JM38510/30103B2A is not explicitly published in the available packaging addendum, and TI's official datasheet (SN54LS112A) specifies 30 MHz typical for commercial variants. For JM38510/30103B2A, timing performance is validated per MIL-STD-883 TM 5011 at -55°C, 25°C, and +125°C, with guaranteed tPLH/tPHL ≤ 25 ns and tsu/th ≥ 20 ns. System-level clock rate must be derived from these parameters.
Can JM38510/30103B2A be used as a drop-in replacement for SN74LS112ADR?
No, JM38510/30103B2A is not a drop-in replacement for SN74LS112ADR. They differ in package (LCCC-20 vs SOIC-16), temperature range (-55°C to +125°C vs 0°C to +70°C), qualification level (QML-38510 Class B vs commercial), and pinout. The JM38510/30103B2A requires a dedicated land pattern and reflow profile; substituting it for SN74LS112ADR would necessitate PCB redesign and qualification retesting.
