Product details
Overview
JM38510/37204B2A from Texas Instruments is a military-grade octal D-type edge-triggered flip-flop with 3-state outputs, designed for high-reliability bus interface and register applications in aerospace and defense systems. It operates across –55°C to 125°C, features 20-pin LCCC (FK) packaging, supports 30 MHz clock frequency, delivers ±24 mA output drive, and enables bidirectional data flow control via buffered OE input.
For engineers reviewing the JM38510/37204B2A datasheet, JM38510/37204B2A pinout, JM38510/37204B2A application, or JM38510/37204B2A equivalent, this page provides verified military-spec timing, bus-driving capability, thermal performance under extended temperature, and direct substitution guidance for legacy 54ALS374A designs requiring MIL-PRF-38535 compliance.
Technical Context
The JM38510/37204B2A implements eight independent D-type latches triggered on the positive clock edge, with synchronous data capture and asynchronous 3-state output control. Its buffered OE input isolates internal flip-flop operation from output state transitions, allowing data retention during bus contention.
This device belongs to the SN54ALS374A family and conforms to MIL-PRF-38535 Class B requirements. It uses bipolar ALS (Advanced Low-Power Schottky) technology, delivering 30 MHz maximum clock frequency, 10 ns setup time, and 4 ns hold time at –55°C to 125°C - parameters fully tested per military specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | ALS (Advanced Low-Power Schottky) - balances speed and power for military embedded timing paths |
| Operating Temperature | –55°C to 125°C - qualified per MIL-PRF-38535 for flight-critical avionics and ground-based radar systems |
| Max Clock Frequency | 30 MHz - enables real-time sampling of sensor data streams in hardened telemetry interfaces |
| Output Drive | ±24 mA - drives 50 pF loads directly without external buffers in backplane I/O port designs |
| Propagation Delay | tPLH/tPHL ≤ 14/17 ns - ensures deterministic timing margin in synchronous bus arbitration logic |
| Supply Voltage | 4.5 V to 5.5 V - compatible with regulated 5 V military power buses with ±10% tolerance |
| Package Type | LCCC (FK), 20-pin - hermetically sealed ceramic package with 1.27 mm pitch for high-vibration environments |
Pinout & Package
LCCC (FK) package: 20-terminal leadless ceramic chip carrier, 8.89 mm × 8.89 mm body, 1.27 mm terminal pitch, 2.03 mm max height, hermetic seal, suitable for high-reliability board assembly and conformal coating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 7, 8, 13, 14 | Data Inputs (D1–D8) | Asynchronous parallel data inputs synchronized to CLK↑; tolerate VI = –0.5 V to 7 V |
| 2, 5, 6, 9, 12, 15, 16, 19 | Q Outputs (Q1–Q8) | True-level registered outputs; enter high-impedance state when OE = H |
| 11 | OE (Output Enable) | Active-low control; does not affect internal latch state - allows concurrent data loading and bus release |
| 10 | CLK | Positive-edge-triggered clock; minimum pulse width 16.5 ns high/low; synchronizes all 8 D→Q transfers |
| 20 | VCC | Power supply pin; requires local 0.1 µF ceramic decoupling due to fast switching current transients |
| 17 | GND | Ground reference; must be connected to low-inductance plane to maintain noise margin in mixed-signal chassis |
Key Features
| Feature | Design Value |
|---|---|
| 3-State Bus Driving | Enables shared-bus architectures without pull-up resistors or interface logic - reduces component count in I/O expansion modules |
| Full Parallel Access | All 8 D inputs loaded simultaneously on CLK↑ - supports byte-wide register file updates in real-time control firmware |
| Buffered Control Inputs | OE and CLK inputs have Schottky-clamped TTL-compatible thresholds - eliminates need for level-shifting in legacy 5 V systems |
| MIL-PRF-38535 Compliance | Class B screening includes burn-in, temperature cycling, and parametric testing - ensures field reliability in launch vehicle electronics |
| High-Impedance Retention | Outputs remain in Z-state until OE is actively pulled low - prevents bus contention during power sequencing or reset recovery |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ALS374AFK | Same ALS logic family, identical 20-pin LCCC (FK) package, same –55°C to 125°C range; differs only in part marking and traceability documentation | No functional difference; used interchangeably in new designs where TI's standard military part number is preferred over JAN-style nomenclature | Select SNJ54ALS374AFK if sourcing through TI's authorized distribution channel with full QML certification documentation |
| JM38510/37204BRA | Same electrical specs and temperature range, but packaged in 20-pin CDIP (J) instead of LCCC (FK); higher θJA (69°C/W vs. N/A for FK) | Suitable for through-hole prototyping or legacy board rework where LCCC reflow capability is unavailable | Choose JM38510/37204BRA only when LCCC assembly infrastructure is inaccessible; verify thermal derating for sustained 30 MHz operation |
Compared with SNJ54ALS374AFK, JM38510/37204B2A offers identical functionality with JAN-standardized marking and traceability for DoD procurement; versus JM38510/37204BRA, it trades through-hole compatibility for superior thermal resistance and vibration resilience in surface-mount avionics assemblies.

FAQ
What is the operating temperature range certified for JM38510/37204B2A?
JM38510/37204B2A is fully characterized and tested over –55°C to 125°C per MIL-PRF-38535 Class B requirements. This range is validated for all electrical parameters including clock frequency, setup/hold times, and output drive strength - making JM38510/37204B2A suitable for deployment in jet engine compartments and space-qualified payloads.
Does JM38510/37204B2A support true bidirectional data flow?
JM38510/37204B2A does not implement internal bidirectional switching; however, paired devices with complementary OE control enable bidirectional bus exchange as shown in TI's Application Figure 2. Each JM38510/37204B2A provides unidirectional D→Q registration with 3-state outputs - enabling controlled directionality in master-slave I/O port configurations.
What package type and pin count does JM38510/37204B2A use?
JM38510/37204B2A uses a 20-pin leadless ceramic chip carrier (LCCC) package designated FK. Its 8.89 mm × 8.89 mm footprint, 1.27 mm terminal pitch, and hermetic ceramic construction comply with MIL-STD-883 requirements for high-reliability surface-mount assembly in defense electronics.
How does the output-enable (OE) function behave relative to internal flip-flop operation in JM38510/37204B2A?
In JM38510/37204B2A, OE is fully asynchronous and does not affect internal latch behavior. When OE is high, outputs go to high-impedance regardless of CLK or D states; internal Q values remain unchanged and can be updated on subsequent CLK↑ edges. This allows seamless bus arbitration without disrupting pipeline registers.
Is JM38510/37204B2A pin-compatible with commercial SN74ALS374A variants?
No - JM38510/37204B2A uses the 20-pin LCCC (FK) package, whereas commercial SN74ALS374A parts use SOIC (DW), PDIP (N), or SOP (NS) packages. Pin functions are identical (D1–D8, Q1–Q8, CLK, OE, VCC, GND), but physical layout, thermal characteristics, and soldering requirements differ significantly. Board redesign is required for substitution.
