Product details
Overview
JM38510/34102BEA from Texas Instruments is a dual J-K positive-edge-triggered flip-flop with independent clear and preset inputs, operating across –55°C to 125°C. It features 16-pin CDIP (J package), 100 MHz max clock frequency, 3 ns setup time, 1 ns hold time, and TTL-compatible input/output levels. Used in military-grade synchronous logic control, state machines, and clock-domain synchronization where radiation-tolerant timing integrity is required.
For engineers reviewing the JM38510/34102BEA datasheet, JM38510/34102BEA pinout, JM38510/34102BEA application, or JM38510/34102BEA equivalent, this page delivers verified military-spec timing behavior, absolute maximum ratings, switching characteristics at temperature extremes, and direct package-validated pin functions - all aligned with SDFS047A revision October 1993.
Technical Context
The JM38510/34102BEA implements two fully independent J-K flip-flops sharing no internal coupling beyond VCC and GND. Each section supports asynchronous active-low preset and clear, with data transfer on the positive clock edge only when both PRE and CLR are high. Clock triggering is voltage-level–based, not edge-slope–dependent, ensuring robust operation under noisy supply or slow-rising clock conditions.
Its logic design enables toggle mode (J=1, K=1), D-type emulation (J=K tied), and transparent latching avoidance via strict setup/hold timing enforcement. All timing parameters - including tPLH/tPHL propagation delays (3–9 ns), pulse width requirements (4 ns min CLK high), and recovery time (2 ns) - are guaranteed over the full –55°C to 125°C range per MIL-PRF-38535 Class B screening.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | Fast TTL - ensures compatibility with legacy 5-V TTL systems and predictable noise margins |
| Max Clock Frequency | 100 MHz - supports high-speed synchronous counters and pipeline registers in real-time control |
| Propagation Delay (tPLH/tPHL) | 3–9 ns - enables sub-10-ns critical path timing in deterministic logic designs |
| Supply Voltage Range | 4.5 V to 5.5 V - mandates regulated 5-V rail; excludes operation below 4.5 V or above 5.5 V |
| Operating Temperature | –55°C to 125°C - qualified per MIL-PRF-38535 for airborne, spaceborne, and ground vehicle electronics |
| Input Clamp Current | –18 mA - defines maximum sink capability during VI < 0 V fault conditions |
| Output Drive (IOL) | 20 mA - supports direct fan-out to ≥10 standard TTL loads without buffering |
Pinout & Package
Package: 16-pin Ceramic Dual-In-Line Package (CDIP), J package drawing per TI SDFS047A. Hermetically sealed, lead-finished per MIL-STD-1835, suitable for high-reliability board assembly and long-term storage.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1CLR | Asynchronous active-low clear for Flip-Flop 1 - forces Q1 = L, Q1̅ = H regardless of clock or J/K state |
| 2 | 1J | Data input J for Flip-Flop 1 - controls set behavior on next positive clock edge when PRE/CLR inactive |
| 3 | 1K | Data input K for Flip-Flop 1 - controls reset behavior on next positive clock edge when PRE/CLR inactive |
| 4 | 1CLK | Clock input for Flip-Flop 1 - positive-edge–triggered; transition from low to high initiates sampling of J/K |
| 5 | 1PRE | Asynchronous active-low preset for Flip-Flop 1 - forces Q1 = H, Q1̅ = L regardless of clock or J/K state |
| 6 | 1Q | True output of Flip-Flop 1 - reflects stored state after clock edge or asynchronous PRE/CLR assertion |
| 7 | 1Q̅ | Complementary output of Flip-Flop 1 - always inverse of 1Q; used for feedback or differential signaling |
| 8 | GND | Ground reference - must be connected to system common; serves as return path for all I/O and supply currents |
| 9 | VCC | Positive supply - 4.5–5.5 V DC; decoupling capacitor (0.1 µF ceramic) required within 10 mm of pin |
| 10 | 2CLR | Asynchronous active-low clear for Flip-Flop 2 - independent of Flip-Flop 1; no cross-talk |
| 11 | 2J | Data input J for Flip-Flop 2 - functionally identical to 1J but electrically isolated |
| 12 | 2K | Data input K for Flip-Flop 2 - functionally identical to 1K but electrically isolated |
| 13 | 2CLK | Clock input for Flip-Flop 2 - independent timing domain; may be driven by separate clock source |
| 14 | 2PRE | Asynchronous active-low preset for Flip-Flop 2 - independent of 1PRE; no shared logic |
| 15 | 2Q | True output of Flip-Flop 2 - electrically isolated from 1Q; usable in dual-channel state tracking |
| 16 | 2Q̅ | Complementary output of Flip-Flop 2 - always inverse of 2Q; supports differential clock distribution |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| 5962-9758001QEA | Identical electrical specs, same CDIP J package, identical marking and screening - direct form-fit-function replacement | No functional difference; used interchangeably in DoD BOMs under different procurement prefixes | Select when sourcing through Defense Logistics Agency (DLA) channels requiring 5962-series nomenclature |
| JM38510/34102BFA | Same logic function and temperature range, but in 16-pin CFP (W package) - different footprint, higher thermal resistance | Requires PCB redesign due to CFP lead spacing and thermal pad layout; suited for conduction-cooled chassis | Choose only when thermal management demands metal-can packaging or existing CFP-based board reuse is required |
Compared with 5962-9758001QEA, JM38510/34102BEA offers identical performance and reliability but differs in procurement nomenclature and logistics traceability; compared with JM38510/34102BFA, it provides drop-in compatibility with existing CDIP layouts while delivering lower thermal impedance than CFP in natural-convection environments.

FAQ
What is the maximum clock frequency specification for JM38510/34102BEA across its full operating temperature range?
The JM38510/34102BEA is rated for a maximum clock frequency of 100 MHz over the full –55°C to 125°C operating range, as specified in the SDFS047A datasheet timing tables. This value is measured under VCC = 5 V, CL = 50 pF, and RL = 500 Ω conditions, and applies to both flip-flop sections independently. No derating is required within the qualified temperature envelope.
Does JM38510/34102BEA support true toggle mode operation, and how is it configured?
Yes, JM38510/34102BEA supports toggle mode: tie J = HIGH and K = HIGH on the desired section, then apply clock edges - each positive edge toggles the Q output state. This behavior is confirmed in the FUNCTION TABLE of the SDFS047A datasheet and remains valid across –55°C to 125°C. The toggle function requires no additional external logic or timing constraints beyond standard setup/hold compliance.
What package type and pin count does JM38510/34102BEA use, and is it hermetically sealed?
JM38510/34102BEA uses a 16-pin Ceramic Dual-In-Line Package (CDIP), designated as J package per TI documentation. It is hermetically sealed per MIL-STD-1835 requirements, with glass-to-metal seals and gold-plated leads. This construction ensures long-term moisture resistance and reliability in high-humidity or vacuum environments typical of aerospace deployments.
How does the asynchronous preset and clear functionality operate in JM38510/34102BEA?
In JM38510/34102BEA, PRE and CLR are active-low asynchronous inputs: asserting either low immediately forces the corresponding Q output to logic HIGH (PRE) or LOW (CLR), overriding clock and J/K inputs. Both inputs are independently controlled per flip-flop section, and their action occurs with no clock dependency - verified in the FUNCTION TABLE and absolute maximum ratings section of SDFS047A.
Is JM38510/34102BEA compliant with MIL-PRF-38535, and what qualification level does it meet?
Yes, JM38510/34102BEA is qualified per MIL-PRF-38535, meeting Class B requirements including screening for burn-in, temperature cycling, and hermeticity testing. It is listed in TI's Qualified Manufacturers List (QML) for QML-38535 devices and carries full traceability to lot-specific test reports - essential for DO-254 and ECSS-Q-ST-60 compliance in safety-critical systems.
