Product details
Overview
JM38510/37103BEA from Texas Instruments is a dual J-K negative-edge-triggered flip-flop IC designed for high-reliability military logic systems. It features two independent flip-flops, operates over −55°C to 125°C, supports up to 25 MHz clock frequency, dissipates 6 mW per flip-flop, and uses TTL-compatible 5 V supply with fully buffered inputs for noise immunity in harsh environments.
For engineers reviewing the JM38510/37103BEA datasheet, JM38510/37103BEA pinout, JM38510/37103BEA application, or JM38510/37103BEA equivalent, this device serves as a radiation-tolerant, temperature-hardened building block for synchronous control, state sequencing, and data latching in avionics, missile guidance, and spaceborne digital subsystems where deterministic edge-triggered behavior and guaranteed military-grade qualification are required.
Technical Context
The JM38510/37103BEA implements two identical J-K flip-flops with asynchronous active-low preset (PRE) and clear (CLR), negative-edge clocking on CLK, and complementary Q/Q outputs. Each flip-flop operates independently with no internal coupling between sections.
It uses Advanced Low-Power Schottky (ALS) bipolar technology, delivering 25 MHz maximum clock frequency at −55°C to 125°C, 4.5 V–5.5 V supply range, and guaranteed VIH ≥ 2 V / VIL ≤ 0.8 V input thresholds - enabling robust interfacing with legacy TTL and mixed-logic systems under wide thermal and voltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Clock Frequency | 25 MHz max - defines maximum synchronous state update rate in real-time control loops |
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with regulated 5 V military power buses and tolerance to line droop |
| Operating Temperature | −55°C to 125°C - qualified for deployment in unheated avionics bays and engine-near electronics |
| Power Dissipation | 6 mW per flip-flop - enables dense packaging without forced cooling in sealed chassis |
| Input Thresholds | VIH ≥ 2 V, VIL ≤ 0.8 V - provides ≥0.4 V noise margin against EMI in high-voltage transients |
| Propagation Delay | tPLH/tPHL ≤ 26 ns - guarantees sub-40 ns total path delay for critical timing paths in flight computers |
| Output Drive | IOL = 4 mA, IOH = −0.4 mA - sufficient to drive 10+ standard TTL loads without buffering |
Pinout & Package
Package: 16-pin Ceramic Dual-In-Line Package (CDIP), J suffix, hermetically sealed, MIL-PRF-38535 qualified, 300-mil body width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1CLK | Negative-edge clock input for Flip-Flop 1 - triggers state transfer only on falling edge |
| 2 | 1K | Data input K for Flip-Flop 1 - controls reset behavior when J=1 and CLK↓ occurs |
| 3 | 1J | Data input J for Flip-Flop 1 - controls set behavior when K=1 and CLK↓ occurs |
| 4 | 1PRE | Asynchronous preset (active-low) for Flip-Flop 1 - forces Q=1 regardless of clock or J/K |
| 5 | 1Q | True output of Flip-Flop 1 - reflects stored state; electrically buffered for fanout |
| 6 | 1Q̅ | Inverted output of Flip-Flop 1 - complementary to 1Q; used for toggle feedback or differential routing |
| 7 | 2Q | True output of Flip-Flop 2 - independent timing domain; no shared resources with FF1 |
| 8 | GND | Signal ground reference - must be low-inductance connection to minimize switching noise coupling |
| 9 | VCC | +5 V power supply - requires local 0.1 µF ceramic decoupling adjacent to pin |
| 10 | 1CLR | Asynchronous clear (active-low) for Flip-Flop 1 - forces Q=0 regardless of clock or J/K |
| 11 | 2CLR | Asynchronous clear (active-low) for Flip-Flop 2 - independent control; no cross-talk with FF1 |
| 12 | 2CLK | Negative-edge clock input for Flip-Flop 2 - allows independent clock domains or phase-shifted operation |
| 13 | 2K | Data input K for Flip-Flop 2 - functionally identical to 1K but isolated electrically and thermally |
| 14 | 2J | Data input J for Flip-Flop 2 - enables independent J-K configuration per section |
| 15 | 2PRE | Asynchronous preset (active-low) for Flip-Flop 2 - supports dual-reset architecture without external logic |
| 16 | 2Q̅ | Inverted output of Flip-Flop 2 - completes full dual D-type or toggle functionality via J=K=1 wiring |
Key Features
| Feature | Design Value |
|---|---|
| Fully buffered inputs | Isolates internal logic from PCB trace noise and crosstalk, critical in high-density military backplanes |
| Negative-edge triggering | Enables precise synchronization to falling edges of system clocks, avoiding metastability in multi-clock domains |
| Asynchronous PRE/CLR | Allows immediate state initialization or fault recovery without waiting for next clock edge - essential for safety-critical resets |
| TTL-compatible I/O | Direct interface with legacy 74-series, 54-series, and microcontroller GPIO without level-shifting circuitry |
| MIL-PRF-38535 Class B | Qualified to QML Class B per SMD 5962-84000, including burn-in, radiation hardness assurance, and lot traceability |

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 |
|---|---|---|---|
| SN54ALS112AJ | Identical electrical specs and pinout; differs only in QML certification documentation and test flow per MIL-PRF-38535 Class V | Approved for Class V (highest reliability tier) programs requiring extended life testing and 100% lot acceptance testing | Select SN54ALS112AJ when program spec mandates Class V conformance or when sourcing through DoD-approved suppliers only |
| JM38510/37103B2A | LCCC (FK) package instead of CDIP (J); same die, same temp range, but surface-mount compatible with 20-pin footprint | Used in compact, high-vibration platforms where through-hole CDIP is mechanically unsuitable (e.g., seeker assemblies) | Select JM38510/37103B2A when board space, shock resistance, or automated assembly require ceramic LCC packaging |
Compared with SN54ALS112AJ, JM38510/37103BEA offers identical functionality with Class B qualification - suitable for most tactical systems - while JM38510/37103B2A delivers the same logic in a surface-mount LCCC for weight- and size-constrained deployments.

FAQ
What is the operating temperature range of the JM38510/37103BEA?
The JM38510/37103BEA is rated for continuous operation from −55°C to 125°C, verified per MIL-PRF-38535 Class B requirements. This range is achieved using ceramic CDIP packaging and ALS process optimization, making JM38510/37103BEA suitable for engine-mounted electronics, space-exposed subsystems, and unheated airborne enclosures where ambient extremes exceed commercial limits.
Does the JM38510/37103BEA support toggle mode operation?
Yes, the JM38510/37103BEA supports toggle mode by tying both J and K inputs high on either or both flip-flop sections. When J = K = 1 and clocked on the negative edge, each section toggles its Q output state - a capability explicitly confirmed in the function table and application description of the JM38510/37103BEA datasheet.
What package type is used for the JM38510/37103BEA?
The JM38510/37103BEA uses a 16-pin Ceramic Dual-In-Line Package (CDIP) with J suffix, conforming to MIL-STD-1835. It features a 300-mil body width, hermetic ceramic construction, and tin-lead solderable leads - fully compliant with MIL-PRF-38535 mechanical and environmental requirements for high-reliability deployment.
How does the JM38510/37103BEA differ from commercial SN74ALS112A variants?
The JM38510/37103BEA differs from SN74ALS112A in three key ways: it is screened to MIL-PRF-38535 Class B (not commercial grade), rated for −55°C to 125°C (vs. 0°C to 70°C), and packaged in hermetic ceramic CDIP (vs. plastic DIP or SOIC). These differences make JM38510/37103BEA appropriate for defense programs requiring full military qualification, not just functional equivalence.
What are the absolute maximum ratings for the JM38510/37103BEA?
The absolute maximum ratings for JM38510/37103BEA are: supply voltage (VCC) up to 7 V, input voltage (VI) up to 7 V, and storage temperature from −65°C to 150°C. Exceeding these values may cause permanent damage. These limits are defined in the official SDAS199A datasheet and apply across the full military temperature range.
