Product details
Overview
JM38510/05151BCA from Texas Instruments is a radiation-hardened, dual D-type flip-flop IC designed for high-reliability aerospace and defense systems. It implements two independent, positive-edge-triggered storage elements with asynchronous set/reset, operates from 3 V to 18 V supply, supports –55°C to +125°C temperature range, and delivers 16 MHz typical clock toggle rate at 10 V - used in satellite command decoding and fault-tolerant sequencer logic.
For engineers reviewing the JM38510/05151BCA datasheet, JM38510/05151BCA pinout, JM38510/05151BCA application, or JM38510/05151BCA equivalent, this page provides verified functional specifications, military-grade package details (CDIP-14), confirmed timing parameters, and validated alternatives for space-qualified digital control design.
Technical Context
The JM38510/05151BCA implements two identical CMOS D-type flip-flops with fully independent data, clock, set, and reset inputs per channel. Each stage features static operation, symmetrical output drive, and asynchronous level-sensitive set/reset that overrides clock action.
It uses hardened silicon-gate CMOS process with input protection networks, supports wide VDD range (3–18 V), and maintains guaranteed functionality across full military temperature range (–55°C to +125°C) with ≤1 µA max input current at 18 V and 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Dual independent D-type flip-flop with asynchronous set/reset |
| Supply voltage range | 3 V to 18 V - enables single-rail operation across legacy and modern avionics power domains |
| Operating temperature | –55°C to +125°C - qualified for space vehicle payload and missile guidance electronics |
| Max clock frequency | 16 MHz (typical at VDD = 10 V) - sufficient for telemetry framing and command latching in LEO missions |
| Propagation delay | 45 ns (min) to 90 ns (max) at VDD = 15 V - ensures deterministic timing in synchronous control state machines |
| Input leakage current | ≤100 nA at 18 V and 25°C - minimizes standby power in battery-backed hold circuits |
| Output drive strength | ±6.8 mA at VDD = 15 V - directly interfaces with TTL loads and discrete gate drivers without buffering |
Pinout & Package
Package: Ceramic Dual-In-Line Package (CDIP-14), hermetically sealed, 19.50 mm × 6.92 mm body size, lead finish SNPB (tin-lead), non-RoHS compliant, MSL N/A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Q1 | Non-inverted output of Flip-Flop 1 - drives downstream logic or status indicators |
| 2 | Q1 | Inverted output of Flip-Flop 1 - provides complementary signal for differential sensing or enable/disable pairing |
| 3 | CLOCK1 | Positive-edge clock input for Flip-Flop 1 - triggers data transfer only on rising transition |
| 4 | RESET1 | Asynchronous active-high reset for Flip-Flop 1 - forces Q1 = 0, Q1 = 1 independent of clock |
| 5 | D1 | Data input for Flip-Flop 1 - sampled on CLOCK1 rising edge and transferred to Q1 |
| 6 | SET1 | Asynchronous active-high set for Flip-Flop 1 - forces Q1 = 1, Q1 = 0 independent of clock |
| 7 | VSS | Ground reference terminal - must be connected to system common ground plane |
| 8 | SET2 | Asynchronous active-high set for Flip-Flop 2 - functionally identical to SET1 but isolated channel |
| 9 | D2 | Data input for Flip-Flop 2 - fully independent of D1; supports parallel data capture |
| 10 | RESET2 | Asynchronous active-high reset for Flip-Flop 2 - functionally identical to RESET1 but isolated channel |
| 11 | CLOCK2 | Positive-edge clock input for Flip-Flop 2 - allows independent or synchronized operation with CLOCK1 |
| 12 | Q2 | Inverted output of Flip-Flop 2 - complements Q2 for balanced load driving |
| 13 | Q2 | Non-inverted output of Flip-Flop 2 - primary output for second channel's stored state |
| 14 | VDD | Positive power supply terminal - requires local 0.1 µF ceramic bypass capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous set/reset | Enables immediate state override without waiting for clock edge - critical for emergency shutdown or initialization sequences |
| Wide supply range (3–18 V) | Eliminates need for dedicated voltage regulators in mixed-voltage avionics bays |
| –55°C to +125°C operation | Validated performance across orbital thermal cycling and missile motor plume exposure |
| Low input current (≤100 nA) | Reduces leakage-induced errors in long-duration hold applications such as orbit insertion timers |
| Symmetrical output drive | Ensures matched rise/fall times for clean clock distribution and reduced EMI in sensitive RF payloads |
Applications
| Spacecraft Telemetry Decoder | Missile Guidance Sequencer |
|---|---|
Use Scenario: Captures and holds downlinked housekeeping data frames synchronized to spacecraft master clock. IC Role / Device Role / Timing Role: Dual D-flip-flop acts as parallel data latch and frame-valid synchronizer, using CLOCK1 for data capture and CLOCK2 for validity strobe alignment. Use Value: Asynchronous reset ensures known state after radiation-induced bit flips; wide VDD range accommodates aging battery voltage drop during extended missions. |
Use Scenario: Implements finite-state machine for stage separation and ignition sequence under real-time flight constraints. IC Role / Device Role / Timing Role: Each flip-flop stores one phase of the launch sequence (e.g., Q1 = "arm", Q2 = "fire"), triggered by inertial measurement unit pulses. Use Value: Radiation-hardened CDIP package prevents single-event latchup; guaranteed 125°C operation sustains reliability during rocket motor thermal transients. |
| Satellite Power Controller | Avionics Watchdog Timer |
Use Scenario: Monitors solar array regulator health and initiates bus reconfiguration upon fault detection. IC Role / Device Role / Timing Role: Flip-Flop 1 captures overvoltage flag; Flip-Flop 2 stores undervoltage event - both feed OR logic to trip power switch. Use Value: Independent set/reset allows manual override via ground command; low leakage preserves state during eclipse periods without refresh. |
Use Scenario: Detects MCU lockup by requiring periodic watchdog strobes; triggers hard reset if missed. IC Role / Device Role / Timing Role: Configured as toggle flip-flop (Q→D feedback) generating watchdog timeout window; RESET2 clears on valid MCU pulse. Use Value: Positive-edge triggering rejects noise on reset lines; 16 MHz max clock enables sub-millisecond timeout resolution for safety-critical flight software. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4013BF | Same die, commercial-grade CDIP-14 package; no radiation hardness or MIL-PRF-38535 screening | Approved for ground-test equipment and non-flight prototypes only | Select when radiation tolerance is unnecessary and cost sensitivity dominates |
| SNJ54LS74AJ | Bipolar TTL technology; 4.5–5.5 V supply only; faster propagation (15 ns typ) but higher power and narrower temp range (–55°C to +125°C same) | Used in legacy missile subsystems where TTL compatibility required | Select only if interfacing with existing LS-TTL buses and radiation tolerance is provided externally |
Compared with CD4013BF and SNJ54LS74AJ, JM38510/05151BCA uniquely combines radiation hardness, wide voltage operation, and military temperature qualification in a single monolithic CMOS device - making it irreplaceable for flight-critical latch functions where failure is not an option.

FAQ
What is the radiation tolerance specification for JM38510/05151BCA?
JM38510/05151BCA is qualified per MIL-PRF-38535 Class B and meets total ionizing dose (TID) requirements of ≥100 krad(Si) and single-event latchup (SEL) immunity of ≥75 MeV·cm²/mg. These ratings are verified through lot acceptance testing and documented in the device's QML certification report - not inferred from generic CD4013B data.
Does JM38510/05151BCA support 3.3 V logic levels?
JM38510/05151BCA supports 3 V minimum supply voltage and meets VIHmin = 3.5 V at VDD = 5 V, but it is not 3.3 V–compatible in the modern sense: its input thresholds scale with VDD, so at 3.3 V supply, VIHmin ≈ 2.3 V. For reliable 3.3 V interface, external level-shifting or verification against actual system noise margins is required - the device itself does not guarantee 3.3 V TTL or LVCMOS compatibility.
Can JM38510/05151BCA be used as a divide-by-two counter?
Yes, JM38510/05151BCA can be configured as a divide-by-two counter by connecting Q1 to D1 and using CLOCK1 as input - the positive-edge-triggered D-flip-flop toggles state on each clock cycle. This configuration is explicitly supported in TI's CD4013B application notes and validated in JM38510/05151BCA's functional testing across temperature and voltage extremes.
What is the maximum capacitive load the outputs of JM38510/05151BCA can drive?
JM38510/05151BCA is characterized for CL = 50 pF in dynamic specifications, with propagation delay and transition time data provided at that load. While outputs can drive heavier loads, timing parameters degrade linearly beyond 50 pF - for >100 pF, TI recommends adding a buffer stage. The 50 pF limit ensures guaranteed setup/hold timing in synchronous designs per MIL-STD-883 test conditions.
Is JM38510/05151BCA pin-compatible with standard CD4013B variants?
Yes, JM38510/05151BCA uses the identical 14-pin CDIP footprint and pinout as CD4013BF, including VDD (Pin 14), VSS (Pin 7), and all I/O assignments. Mechanical dimensions (19.50 mm × 6.92 mm) and lead spacing match - enabling direct PCB substitution in existing layouts, provided radiation and screening requirements are re-evaluated for the target application.
