Product details
Overview
JM38510/34102BFA 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 CFP packaging, 100 MHz max clock frequency (SN54F109 spec), 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 JM38510/34102BFA datasheet, JM38510/34102BFA pinout, JM38510/34102BFA application, or JM38510/34102BFA equivalent, key selection criteria include military temperature range compliance, CFP package mechanical robustness, J-K toggle and D-type configuration flexibility, and direct compatibility with legacy 54F logic systems.
Technical Context
This device implements two fully independent J-K flip-flops sharing no internal resources beyond VCC and GND. Each section supports asynchronous active-low preset and clear, with data transfer synchronized to the positive edge of CLK. Clock triggering is voltage-level–based-not edge-slope–dependent-ensuring stable operation under varying signal rise times.
The logic function supports four primary modes: set (PRE=low), reset (CLR=low), toggle (J=K=high), and hold (J=K=low), plus transparent D-type behavior when J and K are tied. Output drive capability is rated for 20 mA sink and –1 mA source under recommended conditions, consistent with standard TTL loading requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | F-series TTL - ensures interoperability with SN54F/SN74F system designs and predictable noise margins |
| Operating Temperature | –55°C to 125°C - qualified per MIL-PRF-38535 for sustained operation in avionics, missile guidance, and space-qualified electronics |
| Max Clock Frequency | 100 MHz - enables high-speed sequential logic in real-time control loops and digital signal routing |
| Propagation Delay | 3–8 ns (tPLH/tPHL) - supports sub-10 ns timing budgets in pipelined architectures |

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 | Same logic function, CDIP package (16-pin ceramic DIP) instead of CFP; identical electrical specs and temp range | Preferred for through-hole prototyping or legacy board rework where CFP footprint unavailable | Select when manual soldering, socket-based test fixtures, or heritage board compatibility is required |
| SNJ54F109W | Identical CFP package and marking; same TI military qualification level and screening flow as JM38510/34102BFA | No functional difference - differs only in part numbering convention (SNJ prefix vs. JM prefix) | Interchangeable in all applications; SNJ54F109W is TI's direct manufacturer-marked equivalent |
Compared with 5962-9758001QEA and SNJ54F109W, JM38510/34102BFA offers identical logic performance and military qualification but is optimized for surface-mount CFP assembly with lower profile and improved thermal cycling reliability in vibration-prone environments.

FAQ
What is the maximum clock frequency supported by JM38510/34102BFA?
JM38510/34102BFA supports a maximum clock frequency of 100 MHz under recommended operating conditions (VCC = 5 V, TA = 25°C). This value is confirmed in the switching characteristics table of the official SDFS047A datasheet and applies across the full –55°C to 125°C operating range with appropriate derating for temperature extremes.
Does JM38510/34102BFA support D-type flip-flop functionality?
Yes, JM38510/34102BFA supports D-type operation by tying the J and K inputs together on each section. When J = K, the device behaves as a D flip-flop with data appearing at Q on the next positive clock edge - a documented configuration in the functional description and truth table of the SDFS047A datasheet.
What package type is used for JM38510/34102BFA?
JM38510/34102BFA uses a 16-lead Ceramic Flatpack (CFP) package per MIL-STD-1835 Type W. This hermetic, surface-mount package is specified in TI's Package Option Addendum and verified in the device's orderable part documentation as the sole package for this specific part number.
Is JM38510/34102BFA qualified to MIL-PRF-38535?
Yes, JM38510/34102BFA is fully qualified to MIL-PRF-38535 Class B, including screening, environmental testing, and quality assurance per the specification. This qualification is explicitly stated in TI's official packaging and reliability documentation for the part.
What are the absolute maximum ratings for supply voltage on JM38510/34102BFA?
The absolute maximum supply voltage rating for JM38510/34102BFA is –0.5 V to 7 V, as defined in the Absolute Maximum Ratings table of the SDFS047A datasheet. Operation outside this range risks permanent damage, and recommended operating voltage remains 4.5 V to 5.5 V.
