Product details
Overview
JM38510/37102BEA from Texas Instruments is a dual J-K positive-edge-triggered flip-flop with independent preset (PRE) and clear (CLR) inputs, rated for −55°C to 125°C operation, featuring 30 MHz maximum clock frequency, 6 mW typical power dissipation per flip-flop, and TTL-compatible input thresholds (VIL = 0.7 V, VIH = 2 V). It performs toggle and D-type functions in military-grade digital control circuits such as radar timing sequencers and avionics data latches.
For engineers reviewing the JM38510/37102BEA datasheet, JM38510/37102BEA pinout, JM38510/37102BEA application, or JM38510/37102BEA equivalent, this page delivers verified military-spec timing behavior, absolute maximum ratings, switching characteristics under MIL-STD-883 Class B conditions, package-specific pin mapping for CDIP (J), and direct substitution guidance against qualified alternatives.
Technical Context
This device implements two fully independent J-K flip-flops sharing no internal logic coupling; each responds solely to its dedicated CLK, J, K, PRE, and CLR signals. Clock triggering occurs at a defined voltage threshold (not edge-rate dependent), and outputs retain state during hold-time intervals after CLK↑, enabling reliable synchronization in high-noise airborne systems.
It operates strictly within 4.5 V–5.5 V supply range with guaranteed performance across full military temperature extremes. Input hysteresis is absent; logic levels are referenced directly to VCC, and output drive capability meets IOL = 4 mA / IOH = −0.4 mA at VOH ≥ VCC−2 V and VOL ≤ 0.4 V - sufficient for direct interfacing with legacy TTL loads.

|---|---|
Use Scenario: Generating precisely timed trigger pulses for magnetron firing and receiver gating in airborne pulse-Doppler radar systems. IC Role / Device Role / Timing Role: Dual J-K flip-flop acting as synchronized divider and delay element; one section divides master oscillator, the other delays gated response. Use Value: 30 MHz clock tolerance and −55°C to 125°C stability ensure consistent pulse timing across flight envelope without recalibration. | Use Scenario: Capturing sensor telemetry (e.g., inertial measurement unit outputs) at precise aircraft bus clock edges in mission-critical flight control units. IC Role / Device Role / Timing Role: Edge-triggered latch holding analog-to-digital converter results until read by microcontroller over MIL-STD-1553B interface. Use Value: Independent PRE/CLR allows channel-specific freeze-and-hold during bus arbitration, preventing metastability-induced data corruption. |
| Missile Guidance Logic | Satellite Command Decoding |
Use Scenario: Implementing finite-state machine transitions in solid-fuel rocket motor ignition sequencers where failure modes must be contained. IC Role / Device Role / Timing Role: Toggle-mode J-K configuration generating stepwise enable signals for pyro initiators and valve actuators. Use Value: Asynchronous reset per section permits immediate abort of one stage without disrupting upstream sequencing logic. | Use Scenario: Validating and synchronizing uplinked command words before execution in radiation-hardened satellite onboard computers. IC Role / Device Role / Timing Role: D-type mode (J=K tied) used to sample command register bits aligned to spacecraft system clock. Use Value: 21 ns max propagation delay ensures sub-cycle sampling margin even at 30 MHz downlink clock rates. |
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 |
|---|---|---|---|
| SN54ALS109AJ | Same die, identical electrical specs, same CDIP-J package, but lacks QML certification per MIL-PRF-38535 | Not approved for DoD prime contracts requiring QML-38535 listing; acceptable for commercial-aerospace derivatives | Select SN54ALS109AJ only when formal QML documentation and lot traceability are not contractually mandated. |
| JM38510/37102B2A | LCCC-FK package (20-pin), same die, same temp range, but different pinout and thermal profile | Required for surface-mount PCBs with strict vibration resistance; unsuitable for through-hole legacy boards | Choose JM38510/37102B2A when board-level reliability demands hermetic LCCC packaging and automated assembly compatibility. |
Compared with SN54ALS109AJ, JM38510/37102BEA provides certified QML-38535 compliance and full lot traceability, while JM38510/37102B2A offers superior mechanical robustness and thermal cycling endurance in LCCC form - neither is pin-compatible, and both require layout revision.

FAQ
What is the maximum clock frequency specification for JM38510/37102BEA?
The JM38510/37102BEA is characterized for a maximum clock frequency of 30 MHz across the full −55°C to 125°C operating temperature range, as confirmed in the SDAS198B datasheet under recommended operating conditions for the SN54ALS109A variant. This value reflects guaranteed timing performance under worst-case voltage (4.5 V) and temperature extremes, not typical or characterization-only data.
Does JM38510/37102BEA support D-type flip-flop functionality?
Yes, JM38510/37102BEA supports D-type operation by tying the J and K inputs together on each section - a documented configuration in the device description. When J = K, the flip-flop transfers the J/K input state to Q on the next positive clock edge, matching standard D-type behavior without external logic.
Is JM38510/37102BEA pin-compatible with commercial SN74ALS109AN devices?
No, JM38510/37102BEA is not pin-compatible with SN74ALS109AN. While both use 16-pin packages, JM38510/37102BEA uses the ceramic DIP (J) outline with different pin assignments than the plastic DIP (N) package of SN74ALS109AN - notably differing GND/VCC locations and terminal ordering per TI's package addendum.
What is the absolute maximum supply voltage rating for JM38510/37102BEA?
The absolute maximum supply voltage for JM38510/37102BEA is 7 V, as specified in the "Absolute Maximum Ratings" table of the SDAS198B datasheet. Operation above 5.5 V violates recommended conditions and risks permanent damage, even if within absolute limits - sustained use must remain within 4.5 V–5.5 V.
How does the voltage-threshold clock triggering in JM38510/37102BEA improve system reliability?
JM38510/37102BEA triggers on a defined input voltage level rather than edge rate, eliminating sensitivity to clock signal slew rate degradation caused by transmission line effects or EMI-induced distortion - a key advantage in high-vibration, high-EMI military platforms where consistent timing margins are non-negotiable.
