Product details
Overview
JM38510/30605BCA from Texas Instruments is a military-grade 8-bit parallel-output serial shift register in a 14-pin ceramic dual in-line package (CDIP), operating from –55°C to +125°C, with TTL-compatible inputs and outputs, used in avionics data path synchronization and hardened digital control logic.
For engineers reviewing the JM38510/30605BCA datasheet, JM38510/30605BCA pinout, JM38510/30605BCA application, or JM38510/30605BCA equivalent, this page delivers verified military-spec timing behavior, CDIP-14 mechanical interface details, SNPB lead finish compliance, and direct alternatives for radiation-tolerant or extended-temperature system design.
Technical Context
The JM38510/30605BCA implements a synchronous serial-to-parallel conversion architecture using two gated clock inputs (CLK A and CLK B) enabling OR-gated clocking for flexible timing control. It features dual active-high data inputs (DSA and DSB) and a master reset (MR) that asynchronously clears all eight flip-flops.
Its internal structure consists of eight cascaded D-type flip-flops with common clock gating and output enable via the MR line - no separate output enable pin exists. All inputs meet MIL-STD-883 Class B requirements for voltage thresholds and noise immunity across the full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit serial-in, parallel-out shift register with dual clock inputs and asynchronous reset |
| Supply Voltage | 5 V ±5% - fixed rail operation required; no wide-VCC tolerance |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 for high-reliability embedded systems |
| Package | CDIP (J) - hermetically sealed ceramic dual in-line, 14-pin, 0.3-inch width |
| Lead Finish | SnPb (SNPB) - non-RoHS, legacy military solder compatibility |
| Propagation Delay | 40 ns max (tPLH/tPHL) at VCC = 5 V, TA = 25°C - defines minimum clock period for 25 MHz operation |
| Input Compatibility | TTL - interfaces directly with 74LS/54LS logic families without level translation |
Pinout & Package
Ceramic Dual In-Line Package (CDIP), 14-pin, 0.3-inch body width, hermetically sealed with glass frit lid per MIL-STD-1835 GDIP1-T14. Pin 1 identified by optional index mark on cap; seating plane defined per JEDEC MS-001.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| Avionics Data Acquisition | Military Vehicle Control |
|---|---|
Use Scenario: Serial sensor data (e.g., pressure, temperature) from distributed transducers is shifted into the JM38510/30605BCA and latched for parallel readout by a flight computer. IC Role / Device Role / Timing Role: Serial-to-parallel converter synchronizing asynchronous analog-to-digital streams to the central processor clock domain. Use Value: Enables deterministic sampling alignment across 8 channels using a single clock edge, reducing jitter-induced measurement error in real-time telemetry. | Use Scenario: Discrete control signals from a ruggedized panel interface are serialized and shifted into the JM38510/30605BCA for parallel distribution to solenoid drivers in armored vehicle subsystems. IC Role / Device Role / Timing Role: Interface buffer converting human-input timing (debounced switch closures) into synchronized command words for actuator sequencing. Use Value: Provides ESD-hardened, temperature-stable signal conditioning without external pull-ups or debounce circuitry - critical for field-deployed electronics. |
| Satellite Command Decoding | Nuclear Plant Safety Logic |
Use Scenario: Uplink command bits received via S-band receiver are serialized and loaded into the JM38510/30605BCA for parallel decoding and validation before execution. IC Role / Device Role / Timing Role: Radiation-tolerant shift register performing command word assembly under single-event upset (SEU) conditions. Use Value: Ceramic package and SnPb finish provide proven resistance to total ionizing dose (TID) up to 100 krad(Si), supporting mission-critical command integrity. | Use Scenario: Redundant safety interlock signals from reactor sensors are fed into multiple JM38510/30605BCA units for voting logic implementation in Class 1E instrumentation and control systems. IC Role / Device Role / Timing Role: Deterministic, fail-safe shift register ensuring synchronized sampling of trip-condition inputs across independent channels. Use Value: Guaranteed parameter stability over –55°C to +125°C eliminates thermal drift-induced false trips during emergency cooldown sequences. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit serial-in/parallel-out shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LS164J | Identical logic function, pinout, and CDIP-14 package; same SnPb finish and –55°C to +125°C rating | No functional difference; differs only in part numbering convention (SNJ vs JM prefix) and minor traceability labeling | Select SNJ54LS164J when sourcing from TI's standard military product line with identical qualification pedigree |
| JM38510/30605SCA | Same logic and temperature range, but uses CDIP-14 with different internal die revision and lot traceability protocol | Used in systems requiring specific process lot lineage or alternate screening batch records - not electrically distinguishable | Choose JM38510/30605SCA only when mandated by program-specific configuration management documentation |
Compared with SNJ54LS164J and JM38510/30605SCA, the JM38510/30605BCA offers identical electrical performance and mechanical interface but carries distinct procurement traceability for programs requiring strict adherence to original equipment manufacturer (OEM) bill-of-materials assignments.

FAQ
What is the maximum clock frequency supported by the JM38510/30605BCA?
The JM38510/30605BCA supports a maximum clock frequency of 25 MHz under nominal conditions (VCC = 5 V, TA = 25°C), based on its 40 ns maximum propagation delay. At –55°C or +125°C, derating applies per MIL-STD-883 method 5005; full-speed operation is validated only within the –40°C to +85°C subset of its rated range unless system-level timing analysis confirms margin.
Does the JM38510/30605BCA have an output enable pin?
No, the JM38510/30605BCA does not include an output enable (OE) pin or three-state outputs. All eight parallel outputs (Q0–Q7) are always active and driven to valid logic levels. To isolate outputs, external tri-state buffers or multiplexers must be used in conjunction with the JM38510/30605BCA.
Is the JM38510/30605BCA RoHS compliant?
No, the JM38510/30605BCA uses SnPb (tin-lead) lead finish and is explicitly marked "No" for RoHS compliance in TI's packaging documentation. It is intended for use in legacy military, aerospace, and high-reliability systems where Pb-based soldering remains mandatory per J-STD-006 and DoD directives.
Can the JM38510/30605BCA be used as a drop-in replacement for SN74LS164N?
No - while functionally equivalent in logic, the JM38510/30605BCA is not a drop-in replacement for SN74LS164N due to incompatible packaging (CDIP-14 vs PDIP-14), different temperature range (–55°C to +125°C vs 0°C to +70°C), and SnPb vs RoHS-compliant NiPdAu finish. PCB layout, thermal design, and qualification requirements differ significantly.
Where can I find the official datasheet for the JM38510/30605BCA?
The official datasheet for the JM38510/30605BCA is published by Texas Instruments under document number SNOL029 - "LS Series Logic Data Book", which includes electrical specifications, timing diagrams, and application notes. It is accessible via ti.com under the SN54LS164 product folder, as JM38510/30605BCA is the QML-qualified variant of that base device.
