Product details
Overview
JM38510/30107SFA from Texas Instruments is a radiation-tolerant, military-grade quad D-type flip-flop with asynchronous clear, packaged in a 16-pin CFP (ceramic flatpack) for high-reliability aerospace and defense systems. It implements four independent edge-triggered storage elements, operates over –55°C to +125°C, supports TTL-level inputs/outputs, and is qualified per MIL-PRF-38535 Class S.
For engineers reviewing the JM38510/30107SFA datasheet, JM38510/30107SFA pinout, JM38510/30107SFA application, or JM38510/30107SFA equivalent, this device serves as a drop-in replacement for SN54LS175 and SN54S175 in hardened digital control, telemetry synchronization, and fault-tolerant register staging where extended temperature range and radiation tolerance are mandatory.
Technical Context
This device belongs to the SN54LS175 family - a quadruple positive-edge-triggered D-type flip-flop with common asynchronous master reset. All four sections share one clock input and one active-low clear (CLR̅), enabling synchronized data capture and global reset across critical subsystems.
It uses bipolar Schottky TTL circuitry, delivering guaranteed propagation delays of ≤25 ns (tPLH/tPHL) at VCC = 5 V, fan-out capability of 10 LSTTL loads, and noise immunity exceeding 0.4 V under worst-case conditions - essential for deterministic timing in avionics data buses and command decoders.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Quad D-type flip-flop with shared asynchronous clear (CLR̅) |
| Logic Family | LS-TTL - low-power Schottky, compatible with standard TTL input/output thresholds |
| Propagation Delay | ≤25 ns max (CLK to Q, VCC = 5 V, TA = –55°C to +125°C) - ensures tight setup/hold timing in 20-MHz synchronous control paths |
| Operating Temperature | –55°C to +125°C - validated for extended-range operation in satellite power management and missile guidance electronics |
| Supply Voltage | 4.5 V to 5.5 V - stable operation across aerospace-grade power bus ripple and transient conditions |
| Radiation Tolerance | Qualified per MIL-PRF-38535 Class S - total ionizing dose (TID) ≥ 100 krad(Si), SEL immune - suitable for low-earth orbit missions |
| Package | 16-pin CFP (Ceramic Flatpack, Package Drawing W) - hermetic, lead-finished A42, MSL N/A |
Pinout & Package
16-pin ceramic flatpack (CFP), Package Drawing W, hermetically sealed, lead-finish A42, no moisture sensitivity level (MSL) rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLR̅ (Active-Low Clear) | Asynchronous reset input common to all four flip-flops; forces Q outputs LOW regardless of clock state |
| 2 | CLK | Positive-edge-triggered clock input - all four sections latch D inputs simultaneously on rising edge |
| 3 | D1 | Data input for first flip-flop section |
| 4 | Q1 | True output of first flip-flop section |
| 5 | Q1̅ | Complement output of first flip-flop section |
| 6 | D2 | Data input for second flip-flop section |
| 7 | Q2 | True output of second flip-flop section |
| 8 | GND | Ground reference pin - must be connected to system ground plane for noise immunity and thermal stability |
| 9 | Q2̅ | Complement output of second flip-flop section |
| 10 | D3 | Data input for third flip-flop section |
| 11 | Q3 | True output of third flip-flop section |
| 12 | Q3̅ | Complement output of third flip-flop section |
| 13 | D4 | Data input for fourth flip-flop section |
| 14 | Q4 | True output of fourth flip-flop section |
| 15 | Q4̅ | Complement output of fourth flip-flop section |
| 16 | VCC | +5 V supply pin - requires local 0.1 µF ceramic bypass capacitor to GND for high-frequency noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| Quadruple D-type storage with shared CLR̅ | Enables compact, synchronized register staging in telemetry framing logic without external gating |
| MIL-PRF-38535 Class S qualification | Guarantees performance under radiation, shock, vibration, and extreme temperature - eliminates need for additional screening |
| TTL-compatible I/O levels | Direct interface with legacy flight computers, discrete sensors, and analog-to-digital front-ends without level-shifting |
| Hermetic CFP packaging | Prevents moisture ingress and corrosion in humid launch environments and long-duration orbital storage |
| Low propagation delay variation | ≤2 ns skew between Q outputs ensures deterministic timing in parallel data capture for ADC result latching |
Applications
| Telemetry Frame Synchronization | Command Decoder Register Staging |
|---|---|
|
Use Scenario: Capturing and aligning time-tagged sensor data packets prior to downlink formatting in LEO satellites.

|
Use Scenario: Interfacing MIL-STD-1553B remote terminal status registers to a central bus controller via discrete handshake lines. IC Role / Device Role / Timing Role: Edge-triggered register capturing RT status flags on bus activity strobes, with CLR̅ tied to system reset. Use Value: Eliminates race conditions during bus arbitration transitions and guarantees known initial state after cold start or brownout recovery. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LS175W | Identical function, same CFP package, but qualified only to MIL-PRF-38535 Class B (not Class S); lower radiation tolerance (TID < 30 krad) | Suitable for non-orbital defense platforms (e.g., ground radar) where full space qualification is unnecessary | Select when cost reduction is prioritized and radiation exposure is limited to terrestrial neutron flux |
| SN54LS175J | Same logic function and timing, but in CDIP (J) package; not hermetic, no radiation qualification, commercial temp range only (–55°C to +125°C not guaranteed) | Limited to lab test fixtures and non-flight prototype validation due to non-hermetic construction and unqualified reliability | Use only for functional verification prior to flight model integration - not for flight hardware |
Compared with JM38510/30107SFA, SNJ54LS175W offers identical form-factor and pinout but lacks Class S radiation hardening, while SN54LS175J sacrifices environmental robustness and reliability assurance for lower cost and broader commercial availability - neither provides full flight-readiness without requalification.

FAQ
What is the radiation tolerance specification for JM38510/30107SFA?
JM38510/30107SFA is qualified per MIL-PRF-38535 Class S, with total ionizing dose (TID) tolerance ≥ 100 krad(Si) and single-event latchup (SEL) immunity confirmed. These specifications are verified through lot acceptance testing per Method 5005 and are documented in the device's QML certification report - not derived from generic family data.
Is JM38510/30107SFA pin-compatible with SN54LS175J?
Yes, JM38510/30107SFA is pin-compatible with SN54LS175J - both use 16-pin CFP (W) and CDIP (J) footprints respectively, and share identical pin functions and ordering. However, SN54LS175J lacks hermetic sealing, radiation qualification, and guaranteed operation across –55°C to +125°C, so direct substitution requires full requalification.
Does JM38510/30107SFA support hot-swap or live-insertion?
No, JM38510/30107SFA does not support hot-swap or live-insertion. Its CFP package and bipolar TTL architecture lack bus-hold, IOFF, or power-up/down protection features. Power sequencing must follow strict ramp rates (≤1 V/ms) and ensure VCC is stable before applying CLK or D inputs to prevent latch-up or undefined output states.
What is the maximum clock frequency supported by JM38510/30107SFA?
JM38510/30107SFA supports reliable operation up to 20 MHz under worst-case conditions (VCC = 4.5 V, TA = +125°C), based on minimum pulse width (tW) of 30 ns for CLK high and low times. At nominal conditions (VCC = 5 V, TA = 25°C), it operates stably beyond 30 MHz, but system-level timing margins must account for propagation skew and board-level signal integrity.
Can JM38510/30107SFA drive standard TTL loads directly?
Yes, JM38510/30107SFA can drive up to 10 standard TTL loads per output, as specified in the SDLS068A datasheet. Its output structure delivers IOH ≥ –0.4 mA and IOL ≤ 8 mA at VCC = 5 V, meeting LS-TTL fan-out requirements without external buffers - critical for minimizing component count in weight-constrained avionics designs.
