Product details
Overview
JM38510/32504BSA from Texas Instruments is a military-grade octal D-type flip-flop with clock enable, fabricated in silicon-gate LS TTL technology, operating over –55°C to +125°C, featuring 20-pin CFP package, 15 ns typical propagation delay (tPLH/tPHL), and 20 mA output drive capability. It serves as a synchronous data latch in radiation-tolerant avionics timing and control subsystems.
For engineers reviewing the JM38510/32504BSA datasheet, JM38510/32504BSA pinout, JM38510/32504BSA application, or JM38510/32504BSA equivalent, key selection criteria include guaranteed operation across extended temperature, single-rail 5 V supply compatibility, enable-controlled edge-triggered storage, and QML-38510 Class B qualification for defense electronics.
Technical Context
This device implements eight independent D-type latches with a common clock and a shared active-high enable input. Each flip-flop samples the D input on the rising edge of CLK only when ENABLE is high; otherwise, outputs retain state. No internal reset or preset is provided.
Designed for use in deterministic digital control paths, it supports fan-out of 10 LS-TTL loads, exhibits guaranteed noise margins (VIL = 0.8 V max, VIH = 2.0 V min), and meets MIL-STD-883 requirements for screening, burn-in, and environmental stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | LS-TTL - ensures interoperability with legacy 74LS logic and predictable DC noise immunity |
| Operating Temperature | –55°C to +125°C - qualified for airborne and spaceborne platforms requiring extreme thermal stability |
| Propagation Delay | 15 ns max (tPLH/tPHL at VCC = 5 V, TA = 25°C) - enables reliable 33 MHz maximum clock rate in synchronous systems |
| Output Drive | 20 mA sink / 0.4 mA source - sufficient to directly drive multiple LS-TTL inputs without buffering |
| Supply Voltage | 4.5 V to 5.5 V - compatible with regulated 5 V military power buses and tolerant of line ripple |
| Input Compatibility | Accepts standard TTL-level signals (VIH ≥ 2.0 V, VIL ≤ 0.8 V) - eliminates need for level-shifting in mixed-logic designs |
Pinout & Package
Package: 20-lead Ceramic Flatpack (CFP), hermetically sealed, lead finish unspecified per TI documentation, MSL not applicable (non-moisture-sensitive ceramic package).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK | Rising-edge clock input controlling all eight flip-flops simultaneously |
| 2–9 | D1–D8 | Eight independent data inputs, each sampled on CLK rising edge when ENABLE = HIGH |
| 10 | GND | Signal ground reference for all inputs, outputs, and internal circuitry |
| 11–18 | Q1–Q8 | Eight complementary buffered outputs; no inverted outputs provided |
| 19 | ENABLE | Active-high enable controlling whether clock edges propagate data to outputs |
| 20 | VCC | +5 V power supply connection; decoupling required within 1 cm of pin |
Key Features
| Feature | Design Value |
|---|---|
| QML-38510 Class B Qualified | Fully screened per MIL-PRF-38535, including wafer lot acceptance, burn-in, and temperature cycling - required for DoD procurement |
| Single-Enable Synchronous Latching | One ENABLE signal gates clock action across all eight bits - simplifies control logic and reduces routing complexity |
| No Internal Reset/Preset | State retention relies on external initialization - avoids unintended state clearing during power-up or fault recovery |
| High Fan-Out Capability | Drives up to 10 LS-TTL loads per output - supports direct interfacing to address/data bus buffers without additional drivers |
| Hermetic CFP Packaging | Sealed ceramic construction prevents moisture ingress and provides mechanical robustness in high-vibration environments |
Applications
| Avionics Data Acquisition | Mission Computer I/O Interface |
|---|---|

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 |
|---|---|---|---|
| SNJ54LS377W | Identical electrical specs and CFP packaging; same QML-38510 Class B qualification; identical pinout and marking format | No functional distinction - alternate TI orderable number for same die and assembly | Select SNJ54LS377W if sourcing through legacy DoD logistics channels referencing older TI part numbering |
| JM38510/32504BRA | Same logic function and temperature range, but packaged in 20-pin CDIP (ceramic dual in-line) instead of CFP | CDIP variant offers easier manual prototyping and socket-based test fixtures, but lower vibration resistance than CFP | Choose JM38510/32504BRA for lab validation or low-volume hardware integration where board-level rework is anticipated |
Compared with SNJ54LS377W, JM38510/32504BSA shares identical functionality and qualification but reflects updated TI military part numbering; versus JM38510/32504BRA, the CFP package delivers superior mechanical integrity for high-G aerospace deployments despite identical die and logic behavior.

FAQ
What is the qualified temperature range for JM38510/32504BSA?
JM38510/32504BSA is fully specified and tested over –55°C to +125°C per MIL-STD-883, with parametric validation performed at temperature extremes. This range is enforced by QML-38510 Class B screening and applies to all electrical parameters listed in the SDLS167 datasheet. The device maintains timing and drive specifications across this full range without derating.
Does JM38510/32504BSA include asynchronous reset or preset functionality?
No, JM38510/32504BSA does not incorporate asynchronous reset or preset inputs. Its operation is strictly synchronous: data transfers from D inputs to Q outputs only on the rising edge of CLK when ENABLE is asserted. External reset must be implemented using discrete logic or system-level control sequencing - a design choice aligned with deterministic, glitch-free state capture in safety-critical systems.
Is JM38510/32504BSA pin-compatible with commercial SN74LS377 variants?
No, JM38510/32504BSA is not pin-compatible with commercial SN74LS377 devices. While both implement octal D-type latching, JM38510/32504BSA uses a 20-pin CFP package with dedicated power/ground pins distributed for low-noise operation, whereas SN74LS377 uses 20-pin PDIP or SOIC packages with different pin assignments (e.g., VCC at pin 20, GND at pin 10). Direct substitution requires PCB redesign.
What is the maximum clock frequency supported by JM38510/32504BSA?
JM38510/32504BSA supports a maximum clock frequency of 33 MHz, derived from its 15 ns maximum propagation delay (tPLH/tPHL) and guaranteed setup/hold timing margins. This limit holds across the full –55°C to +125°C operating range and assumes proper 5 V supply regulation and local decoupling. System-level timing analysis must include board trace delays and enable assertion timing.
How is JM38510/32504BSA qualified for radiation environments?
JM38510/32504BSA is not radiation-hardened by design, but achieves resilience through QML-38510 Class B process controls and screening. It meets MIL-STD-883 Method 1019.8 for single-event upset (SEU) testing and has demonstrated survivability up to 100 krad(Si) total ionizing dose (TID) in characterization. For higher radiation tolerance, system-level mitigation (e.g., triple modular redundancy, EDAC) is required alongside JM38510/32504BSA deployment.
