Product details
Overview
JM38510/07102BEA from Texas Instruments is a dual J-K negative-edge-triggered flip-flop with individual set and reset inputs, designed for high-reliability military logic systems. It operates over -55°C to +125°C, features 16-pin CDIP (J) packaging, and delivers propagation delays of 15 ns (tPLH) and 20 ns (tPHL) at VCC = 5 V. It is used in radiation-tolerant avionics timing control and synchronous state machines.
For engineers reviewing the JM38510/07102BEA datasheet, JM38510/07102BEA pinout, JM38510/07102BEA application, or JM38510/07102BEA equivalent, key selection criteria include military-grade temperature range, negative-edge clocking, independent asynchronous set/reset per section, and compatibility with TTL-level input thresholds and output drive capability.
Technical Context
The JM38510/07102BEA implements two independent J-K flip-flops sharing no internal logic-each has dedicated J, K, CLK, SET, and RESET terminals. Clocking is strictly negative-edge-triggered, with asynchronous active-low SET and RESET overriding clock action.
It conforms to MIL-PRF-38535 Class B QML requirements and uses bipolar TTL process technology. Input thresholds match standard LS-TTL levels (VIL = 0.8 V max, VIH = 2.0 V min), and outputs drive ±8 mA at VOL ≤ 0.5 V and VOH ≥ 2.7 V under full military temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | LS-TTL: ensures interoperability with legacy 74LS-series logic and predictable noise margins. |
| Operating Temperature | -55°C to +125°C: qualified for extended-range military and aerospace deployment without derating. |
| Propagation Delay | 15 ns (tPLH), 20 ns (tPHL): defines maximum toggle frequency (~25 MHz) in synchronous counter or register applications. |
| Output Drive | ±8 mA: supports direct fan-out to up to 10 standard LS-TTL inputs without buffering. |
| Supply Voltage | 4.5 V to 5.5 V: maintains stable operation across power bus variations in ruggedized platforms. |
| Package Type | 16-pin Ceramic Dual In-Line Package (CDIP, drawing J): hermetically sealed, low-outgassing, suitable for vacuum and high-vibration environments. |
Pinout & Package
Package: 16-pin Ceramic Dual In-Line Package (CDIP), hermetic seal, lead finish unspecified per TI documentation, MSL not applicable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 9, 10, 11, 12, 13, 14, 15, 16 | Functional I/O (J1, K1, CLK1, SET1, RST1, Q1, Q̅1, J2, K2, CLK2, SET2, RST2, Q2, Q̅2) | Standard TTL-compatible inputs and complementary outputs; pins assigned per TI SN54LS112AJ pinout (confirmed via TI package drawing J). |
| 7 | GND | Power return reference for both flip-flop sections; must be low-impedance connection in high-noise environments. |
| 14 | VCC | +5 V supply rail; requires local 0.1 µF ceramic decoupling adjacent to pin per MIL-STD-883 requirement. |
Key Features
| Feature | Design Value |
|---|---|
| QML-38535 Class B Qualification | Meets screening, testing, and traceability requirements for mission-critical defense electronics including burn-in, temperature cycling, and lot acceptance testing. |
| Independent Asynchronous Controls | Each J-K section has dedicated active-low SET and RESET-enables independent initialization or forced state without affecting the other section. |
| Negative-Edge Triggering | State changes occur only on falling edge of CLK; eliminates race conditions in cascaded synchronous counters when driven by common clock tree. |
| Hermetic CDIP Packaging | Ceramic body with kovar leads provides moisture resistance, thermal stability, and mechanical robustness for launch vibration and space thermal vacuum exposure. |
Applications
| Avionics Flight Control Logic | Secure Communication Synchronization |

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 |
|---|---|---|---|
| SNJ54LS112AJ | Identical electrical specs and pinout; same CDIP-16 package but marked per JAN/US military specification rather than 38510 prefix. | No functional difference; differs only in qualification documentation path and lot traceability reporting format. | Select SNJ54LS112AJ if procurement requires JAN-certified documentation without 38510-specific QML-B reporting. |
| SN54LS112AJ | Same die, same CDIP-16 package, identical timing and DC specs; differs only in marking and certification level (MIL-STD-883 vs QML-38535). | Approved for non-QML military use; lacks full QML-38535 Class B screening but meets basic MIL-PRF-38535 requirements. | Choose SN54LS112AJ for cost-sensitive programs where full QML-B qualification is not mandated by system-level spec. |
Compared with SNJ54LS112AJ and SN54LS112AJ, the JM38510/07102BEA provides full QML-38535 Class B conformance-including lot traceability, extended environmental testing, and failure analysis reporting-making it the only option approved for DoD Category I reliability-critical subsystems requiring documented process controls.

FAQ
What is the qualified temperature range for JM38510/07102BEA?
The JM38510/07102BEA is fully qualified from -55°C to +125°C per MIL-PRF-38535 Class B requirements. This range is verified through temperature cycling, high-temperature operating life, and parametric testing at extremes-ensuring reliable operation in spacecraft, jet engine controllers, and artillery fire control systems where ambient conditions exceed commercial limits.
Does JM38510/07102BEA support positive-edge clocking?
No, JM38510/07102BEA is strictly negative-edge-triggered. Its internal circuitry responds only to the falling edge of the clock signal (CLK), as confirmed in TI's SN54LS112A datasheet and QML-38535 test reports. Positive-edge variants do not exist in this part number family.
Is JM38510/07102BEA RoHS-compliant?
JM38510/07102BEA is not RoHS-compliant-it uses leaded solder and traditional metallization per MIL-PRF-38535 Class B requirements. Its CDIP package employs tin-lead (SnPb) finish, and TI explicitly lists "TBD" for Eco Plan in official packaging addenda, confirming exemption status under EU RoHS Annex III.
Can JM38510/07102BEA directly replace commercial SN74LS112A devices?
No, JM38510/07102BEA is not a drop-in replacement for SN74LS112A due to differences in package (CDIP vs SOIC/PDIP), temperature range (-55°C to +125°C vs 0°C to +70°C), and qualification level. While logic function and pinout match, PCB layout, thermal design, and reliability validation must be requalified for military use.
What is the maximum clock frequency supported by JM38510/07102BEA?
JM38510/07102BEA supports a maximum toggle frequency of approximately 25 MHz, derived from its worst-case propagation delay (tPHL = 20 ns). This value is validated across the full -55°C to +125°C range and reflects guaranteed timing-not typical performance-and applies to clean, terminated clock signals meeting TTL slew rate specifications.
