Product details
Overview
JM38510/37201BEA from Texas Instruments is a military-grade hex D-type flip-flop with asynchronous clear, implemented in TTL-compatible ALS logic. It contains six independent positive-edge-triggered storage elements, single-rail outputs, buffered clock and direct-clear inputs, and operates across –55°C to 125°C. It is used in radiation-tolerant buffer/storage registers and shift registers within avionics timing and control subsystems.
For engineers reviewing the JM38510/37201BEA datasheet, JM38510/37201BEA pinout, JM38510/37201BEA application, or JM38510/37201BEA equivalent, key selection criteria include guaranteed operation at –55°C to 125°C, 40 MHz maximum clock frequency, 19 mA typical ICC at VCC = 5.5 V, and CDIP-16 packaging compliant with MIL-PRF-38535 Class B screening.
Technical Context
This device implements six independent D-type latches using bipolar ALS (Advanced Low-Power Schottky) TTL circuitry. Each flip-flop transfers data from its D input to Q output on the positive-going edge of CLK, provided setup and hold time requirements are met (tsu = 15 ns, th = 0 ns over full temperature range). CLR is asynchronous and active-low, forcing Q to logic low regardless of clock state.
All inputs and outputs are fully buffered for high noise immunity and isolation. The device is designed for direct compatibility with standard TTL families and requires no external pull-ups or level-shifting when interfacing with other 5-V TTL logic. Unused inputs must be tied to VCC or GND per TI SCBA004 guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | ALS (Advanced Low-Power Schottky) TTL - enables 40 MHz operation with 19 mA typical supply current at 5.5 V. |
| Clock Frequency | 40 MHz max (–55°C to 125°C) - defines maximum synchronous data rate in register chains. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5-V TTL power rails; absolute max 7 V prevents latch-up. |
| Propagation Delay | tPLH/tPHL ≤ 20 ns (CLK to Q) - ensures predictable timing margins in critical control-path logic. |
| Output Drive | IOL = 4 mA / IOH = –0.4 mA - sufficient to drive 10 standard TTL loads without fanout degradation. |
| Operating Temperature | –55°C to 125°C - qualified per MIL-PRF-38535 for aerospace, defense, and downhole applications. |
| Package | CDIP-16 (J package) - hermetically sealed ceramic dual in-line, lead finish per MIL-STD-1835. |
Pinout & Package
Package: 16-pin Ceramic Dual In-Line Package (CDIP), J outline per MIL-STD-1835, hermetically sealed, lead-finish per manufacturer specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLR | Asynchronous active-low clear input - forces all six Q outputs low independently of clock. |
| 2–7, 9–14 | D1–D6 | Data inputs for six flip-flops - sampled on rising CLK edge if tsu/th timing met. |
| 8 | GND | Ground reference - must be low-impedance connection to minimize switching noise coupling. |
| 15 | CLK | Buffered clock input - positive-edge sensitive; internal buffering isolates from external signal distortion. |
| 16 | VCC | Positive supply - 4.5 V to 5.5 V; decoupling capacitor required near pin for transient current suppression. |
| 17–19 | Q1–Q6 | True outputs - single-rail, totem-pole, TTL-compatible voltage levels (VOH ≥ VCC–2 V, VOL ≤ 0.4 V). |
| 20 | NC | No internal connection - left unconnected; not bonded or routed internally. |
Key Features
| Feature | Design Value |
|---|---|
| Hex D-type architecture | Six independent edge-triggered storage cells enable compact 6-bit register implementation without external gating. |
| Asynchronous clear | Global reset via dedicated CLR pin allows deterministic initialization of all outputs without clock dependency. |
| Full TTL compatibility | Input thresholds (VIH = 2 V, VIL = 0.8 V) and output drive match legacy TTL systems, eliminating interface logic. |
| MIL-PRF-38535 Class B | Screened for high-reliability applications including spaceflight, missile guidance, and nuclear instrumentation. |
| Buffered I/O | Internal buffering minimizes capacitive loading effects and improves noise rejection in electrically noisy environments. |
Applications
| Avionics Data Buffering | Missile Guidance Register Chain |

Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ALS174J | Same ALS logic, identical pinout and timing, but screened to MIL-PRF-38535 Class V (not Class B); lower test coverage. | Approved for less-critical military ground systems where full Class B reliability is not mandated. | Select SNJ54ALS174J only if Class V qualification suffices and cost sensitivity outweighs extended life testing requirements. |
| JM38510/37201B2A | LCCC-20 package (FK outline) vs. CDIP-16; same electrical specs, but different thermal resistance (θJA ≈ 125°C/W vs. 67°C/W) and mounting method. | Preferred for high-vibration environments requiring surface-mount solder joints and reduced mass. | Choose JM38510/37201B2A when board-level shock/vibe performance or higher I/O count density is prioritized over through-hole serviceability. |
Compared with SNJ54ALS174J and JM38510/37201B2A, JM38510/37201BEA offers the highest reliability assurance (Class B), optimal thermal performance in through-hole layouts, and field-proven longevity in flight-critical deployments - making it the default choice for new high-integrity designs.

FAQ
What is the maximum clock frequency supported by JM38510/37201BEA over its full operating temperature range?
JM38510/37201BEA supports a maximum clock frequency of 40 MHz from –55°C to 125°C, as specified in the SDAS207E datasheet timing requirements table. This value is guaranteed for all units meeting MIL-PRF-38535 Class B screening, with tPLH/tPHL propagation delays ≤ 20 ns under worst-case conditions (VCC = 4.5 V, CL = 50 pF).
Does JM38510/37201BEA have complementary (Q and Q̅) outputs?
No, JM38510/37201BEA provides only true (Q) outputs - it is the 'ALS174 variant, not 'ALS175. The 'ALS175 and 'AS175B variants offer double-rail outputs, but JM38510/37201BEA implements six single-rail D-type flip-flops with no inverted outputs. Pin 20 is NC; no Q̅ terminals exist on this part.
What is the recommended decoupling strategy for JM38510/37201BEA in high-reliability PCB layouts?
TI recommends a minimum 0.1 µF ceramic capacitor placed within 5 mm of the VCC (pin 16) and GND (pin 8) pins of JM38510/37201BEA, with short, wide traces. For systems subject to high di/dt transients, add a 4.7 µF tantalum or polymer capacitor nearby. This mitigates supply rail collapse during simultaneous output switching of all six flip-flops.
How does the electrical behavior of JM38510/37201BEA differ from commercial-grade SN74ALS174N?
JM38510/37201BEA shares identical ALS logic design and DC/AC specifications with SN74ALS174N but adds MIL-PRF-38535 Class B screening: extended temperature validation (–55°C to 125°C), burn-in, hermeticity testing, and lot traceability. Electrical parameters like VOH, VOL, and ICC are identical; only reliability assurance and environmental robustness differ.
Can unused D inputs on JM38510/37201BEA be left floating?
No - all unused D inputs on JM38510/37201BEA must be tied to either VCC or GND, as stated in TI application report SCBA004. Floating TTL inputs cause increased ICC, erratic switching, and potential latch-up due to internal transistor bias instability. This requirement applies across the full –55°C to 125°C operating range.
