Product details
Overview
JM38510/37204BRA 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 data latching in avionics, radar, and hardened embedded systems. It operates across –55°C to 125°C, features 24 mA low-level output drive, 12 ns max tPHL propagation delay, and TTL-compatible inputs. It serves as a buffered I/O register in synchronous digital subsystems requiring deterministic timing and bus isolation.
For engineers reviewing the JM38510/37204BRA datasheet, JM38510/37204BRA pinout, JM38510/37204BRA application, or JM38510/37204BRA equivalent, key selection criteria include its MIL-PRF-38535 Class B qualification, CDIP (J) 20-pin package, 30 MHz maximum clock frequency, 10 ns data setup time, and compatibility with ALS logic family voltage thresholds and drive strength.
Technical Context
This device implements eight independent D-type latches triggered on the positive clock edge, each with individually controllable 3-state output enable. Internal buffering isolates OE and CLK inputs from bus loading effects, enabling simultaneous data retention and output disable without affecting latch state.
It uses bipolar ALS (Advanced Low-Power Schottky) technology, delivering higher speed and lower power than standard LS logic while maintaining pin- and function-compatibility with SN54ALS374A. Its electrical behavior is fully characterized per MIL-PRF-38535 requirements, including radiation hardness assurance and extended temperature stress screening.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | ALS (Advanced Low-Power Schottky) - enables 30 MHz operation with 24 mA drive at 5 V while reducing power vs. LS. |
| Clock Frequency (fCLK) | 30 MHz max - supports real-time data capture in high-speed military data buses and telemetry interfaces. |
| Output Drive (IOL) | 24 mA - sufficient to directly drive terminated 50 Ω transmission lines or multiple TTL loads without external buffers. |
| Propagation Delay (tPHL) | 17 ns max - ensures predictable timing margins in synchronous control paths with tight setup/hold windows. |
| Operating Temperature | –55°C to +125°C - qualified for deployment in engine-mounted electronics, missile guidance units, and space-qualified chassis. |
| Supply Voltage (VCC) | 4.5 V to 5.5 V - compatible with regulated 5 V military power supplies and tolerant of transient rail droop. |
| Input Thresholds (VIL/VIH) | 0.8 V / 2.0 V - ensures noise immunity in electrically noisy platforms such as aircraft avionics bays and ground vehicle ECU compartments. |
Pinout & Package
Package: Ceramic Dual-In-Line Package (CDIP), J package, 20-pin, hermetically sealed, lead finish per MIL-STD-1835.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE (Output Enable) | Active-low control: places all eight Q outputs in high-impedance state when high; no effect on internal latch state. |
| 2–9 | 1Q–8Q | True buffered outputs; driven only when OE = low and CLK↑ has occurred; capable of sourcing/sinking 24 mA. |
| 10 | GND | Signal reference plane; must be connected to system ground with low-inductance path for noise immunity. |
| 11 | VCC | +5 V supply input; requires local 0.1 µF ceramic decoupling adjacent to pin for transient current delivery. |
| 12–19 | 1D–8D | Data inputs; sampled on rising edge of CLK; TTL-compatible thresholds ensure interoperability with legacy digital subsystems. |
| 20 | CLK | Positive-edge-triggered clock input; internally buffered to minimize skew across eight flip-flops and reduce fanout loading. |
Key Features
| Feature | Design Value |
|---|---|
| 3-State Bus Driving Outputs | Enables direct connection to shared data buses without pull-ups or interface logic; eliminates contention during multi-master arbitration. |
| MIL-PRF-38535 Class B Qualification | Includes radiation hardness assurance, lot traceability, extended burn-in, and full parametric testing across temperature extremes. |
| Full Parallel Data Access | All eight D inputs and Q outputs are simultaneously accessible-ideal for 8-bit register file implementation in flight computers. |
| Buffered Control Inputs | OE and CLK inputs feature Schottky-clamped buffers that reject fast transients and maintain signal integrity in high-EMI environments. |
| High-Impedance Output Retention | Outputs enter Z-state without altering stored data; allows safe hot-swap of peripheral modules or dynamic bus reconfiguration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN54ALS374AJ | Same ALS logic family, identical pinout and function, but not MIL-PRF-38535 qualified; rated for –55°C to 125°C but lacks radiation assurance and lot traceability. | Suitable for commercial-space or ruggedized industrial use where full military qualification is not mandated. | Select SN54ALS374AJ only if program documentation does not require Class B conformance or radiation tolerance evidence. |
| SN54AS374J | Faster AS family variant: 125 MHz fCLK, 9 ns tPHL, but higher ICC (128 mA active) and reduced noise margin (VIL = 0.7 V). | Better suited for ultra-high-speed digital test equipment or jammer waveform generators where speed outweighs power and noise immunity needs. | Choose SN54AS374J only when design requires >30 MHz operation and can accommodate increased supply current and tighter input threshold control. |

JM38510/37204BRA guarantees 30 MHz maximum clock frequency across its full operating temperature range. Its timing parameters include 10 ns minimum data setup time (tsu) and 4 ns minimum hold time (th), providing robust margin against jitter and skew in synchronous systems using 5 V TTL clock sources with ≤2 ns rise/fall times.
Can JM38510/37204BRA drive terminated 50 Ω transmission lines directly?
Yes, JM38510/37204BRA can directly drive 50 Ω terminated lines: its 24 mA low-level output current (IOL) delivers ≥2.4 V logic high and ≤0.4 V logic low into 50 Ω loads at VCC = 4.5 V, satisfying MIL-STD-1553 and ARINC 429 driver requirements without external line drivers or termination networks.
How does JM38510/37204BRA differ from SN74ALS374A in terms of application suitability?
JM38510/37204BRA is a Class B qualified military part rated for –55°C to +125°C with full MIL-PRF-38535 compliance, while SN74ALS374A is a commercial-grade device rated only for 0°C to +70°C and lacking radiation assurance or extended reliability testing.
