Product details
Overview
JM38510/30103BFA from Texas Instruments is a military-grade dual J-K negative-edge-triggered flip-flop in a 16-pin CFP (ceramic flatpack) package, operating across -55°C to +125°C, with SNPB lead finish and non-RoHS compliance. It implements synchronous data storage and state control in radiation-tolerant avionics timing circuits and hardened logic subsystems.
For engineers reviewing the JM38510/30103BFA datasheet, JM38510/30103BFA pinout, JM38510/30103BFA application, or JM38510/30103BFA equivalent, this device serves as a QML-38510 qualified replacement for legacy SNJ54LS112AW in high-reliability digital control, test instrumentation, and space-qualified sequencers where extended temperature range and hermetic packaging are mandatory.
Technical Context
This device belongs to the SN54LS112A logic family and implements two independent J-K flip-flops with complementary Q and Q̅ outputs, asynchronous preset and clear inputs, and negative-edge clock triggering. Each section operates with guaranteed propagation delays ≤40 ns at VCC = 5V and full military temperature range.
It uses bipolar TTL technology with Schottky-clamped inputs and outputs, supporting fan-out of 10 LS-TTL loads per output. The CFP package provides hermetic sealing and thermal stability required for MIL-PRF-38535 Class B/QML-38510 qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | LS-TTL - ensures compatibility with legacy 74LS-series systems and predictable noise margins. |
| Function | Dual J-K negative-edge-triggered flip-flop - enables synchronous state retention and toggle/divide-by-2 operation per section. |
| Operating Temperature | -55°C to +125°C - supports deployment in aerospace, missile guidance, and downhole electronics without derating. |
| Supply Voltage | 4.5V to 5.5V - maintains stable switching thresholds under wide input rail variation typical in avionics power buses. |
| Propagation Delay (tPLH/tPHL) | ≤40 ns max - guarantees timing predictability in critical control loops with sub-25 MHz clock domains. |
| Package Type | CFP (W), 16-pin ceramic flatpack - provides hermeticity, low outgassing, and mechanical robustness for vacuum and thermal cycling environments. |
| Lead Finish | SNPB (tin-lead) - compliant with MIL-STD-883 method 2009 and suitable for legacy soldering processes used in defense manufacturing. |
Pinout & Package
Package: CFP (W), 16-pin ceramic flatpack with gull-wing leads, 0.050" lead pitch, 0.700" × 0.300" body size, and 0.125" maximum height per MIL-STD-1835.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1CLR̅ | Active-low asynchronous clear for first flip-flop - forces Q1 = 0 regardless of clock or J/K state. |
| 2 | 1CLK | Negative-edge-triggered clock input for first flip-flop - samples J1/K1 on falling edge only. |
| 3 | 1J | Data input J for first flip-flop - sets next-state behavior when CLK falls (J=1,K=0 → set; J=0,K=1 → reset). |
| 4 | 1K | Data input K for first flip-flop - complements J to define toggle, hold, set, or reset action. |
| 5 | 1Q̅ | Inverted output of first flip-flop - provides complementary signal for differential routing or feedback paths. |
| 6 | 1Q | True output of first flip-flop - drives downstream logic or status indicators with LS-TTL compatible voltage levels. |
| 7 | GND | Signal ground reference - must be connected to system ground plane with low-inductance path for noise immunity. |
| 8 | VCC | Positive supply terminal - requires local 0.1 µF ceramic decoupling capacitor placed within 5 mm. |
| 9 | 2Q | True output of second flip-flop - electrically isolated from first section but shares same VCC/GND. |
| 10 | 2Q̅ | Inverted output of second flip-flop - enables dual-channel synchronous sampling or mirrored control signals. |
| 11 | 2K | Data input K for second flip-flop - independent control path allows separate state machines on single die. |
| 12 | 2J | Data input J for second flip-flop - supports independent J-K configuration per section without external gating. |
| 13 | 2CLK | Negative-edge-triggered clock input for second flip-flop - may be tied to 1CLK or driven separately. |
| 14 | 2CLR̅ | Active-low asynchronous clear for second flip-flop - enables independent reset of second stage. |
| 15 | 2PRE̅ | Active-low asynchronous preset for second flip-flop - forces Q2 = 1 independently of clock or data. |
| 16 | 1PRE̅ | Active-low asynchronous preset for first flip-flop - provides independent initialization capability per section. |

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 |
|---|---|---|---|
| SNJ54LS112AW | Identical electrical specs, same CFP-16 package, identical SNPB finish and -55°C to +125°C rating. | No functional difference; differs only in part numbering convention (SNJ vs JM prefix) and lot traceability documentation. | Select SNJ54LS112AW if sourcing through legacy TI military distribution channels requiring SNJ prefix compliance. |
| JM38510/30103BEA | Same logic function and temperature range, but packaged in CDIP (J)-16 instead of CFP (W); non-hermetic, higher moisture sensitivity. | Suitable for board-level applications where hermeticity is not required, but unsuitable for vacuum or high-humidity sealed enclosures. | Choose JM38510/30103BEA only for cost-sensitive ground-based systems where CFP reliability is unnecessary. |
Compared with SNJ54LS112AW, JM38510/30103BFA offers identical performance but aligns with newer TI military part numbering conventions; versus JM38510/30103BEA, it delivers hermetic reliability essential for space and aviation use - making CFP the only viable choice for mission-critical deployments.

FAQ
What is the qualified temperature range for JM38510/30103BFA?
JM38510/30103BFA is fully specified and tested over -55°C to +125°C per MIL-STD-883 method 1010. This range is guaranteed for all electrical parameters including propagation delay, setup/hold times, and output drive strength - no derating is required across the full span, making JM38510/30103BFA suitable for extreme-environment deployment such as stratospheric platforms and deep-space probes.
Is JM38510/30103BFA RoHS compliant?
No, JM38510/30103BFA uses SNPB (tin-lead) lead finish and is explicitly marked "No" for RoHS compliance in TI's official packaging documentation. It is intended for military, aerospace, and legacy industrial applications where Pb-free exemptions apply under JESD67 and MIL-STD-1276 - and cannot be substituted with RoHS-compliant variants without redesign validation.
What is the pin-compatible alternative to JM38510/30103BFA?
SNJ54LS112AW is a pin-, function-, and specification-identical alternative to JM38510/30103BFA, sharing the same CFP-16 package, SNPB finish, -55°C to +125°C rating, and QML-38510 Class B qualification. The only distinction lies in TI's internal part numbering prefix (SNJ vs JM), with no electrical, mechanical, or reliability differences between the two devices.
Does JM38510/30103BFA support positive-edge clocking?
No, JM38510/30103BFA is strictly a negative-edge-triggered device - its internal circuitry samples J and K inputs only on the falling edge of the clock signal. Attempting to use rising-edge clocks will result in undefined or metastable output states. For positive-edge operation, designers must select alternate parts such as SNJ54LS74AW or implement external inverters - which add propagation delay and skew.
What packaging standard does JM38510/30103BFA meet?
JM38510/30103BFA conforms to MIL-STD-1835 for CFP (W) packaging, featuring a 16-pin ceramic flatpack with gull-wing leads, hermetic ceramic body, and 0.050" lead pitch. Its dimensions, marking layout, and mechanical tolerances comply with drawing number SCHEMATIC-30103BFA and are verified per MIL-STD-883 method 2017 for seal integrity.
