Product details
Overview
M38510/30602BEA from Texas Instruments is a military-grade 4-bit universal shift register IC in CDIP-16 package, operating from –55°C to +125°C, with TTL-compatible inputs and outputs, asynchronous clear, and parallel load capability-used in hardened avionics data path synchronization.
For engineers reviewing the M38510/30602BEA datasheet, M38510/30602BEA pinout, M38510/30602BEA application, or M38510/30602BEA equivalent, key selection considerations include its radiation-hardened qualification, extended temperature range, SNPB lead finish, CDIP (J) package mechanical dimensions, and compatibility with legacy 54LS195 logic families.
Technical Context
This device implements synchronous serial-in/serial-out and parallel-in/parallel-out shift register functionality using bipolar TTL circuitry. It features independent clock and clear control lines, enabling precise timing alignment in deterministic real-time systems.
The M38510/30602BEA supports four distinct operating modes-hold, shift right, shift left, and parallel load-selected via two mode-control inputs. Its propagation delay (tPLH/tPHL) is specified at 25 ns max across the full temperature range, ensuring predictable timing in critical control loops.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK | Positive-edge-triggered master clock input controlling all register state transitions |
| 2 | MR | Master reset (asynchronous active-low clear) - forces Q0–Q3 to logic low regardless of clock state |
| 3 | D0 | Parallel data input A (LSB) - loaded into Q0 when S1/S0 = 11 |
| 4 | D1 | Parallel data input B - loaded into Q1 during parallel load mode |
| 5 | D2 | Parallel data input C - loaded into Q2 during parallel load mode |
| 6 | D3 | Parallel data input D (MSB) - loaded into Q3 during parallel load mode |
| 7 | GND | Signal ground reference for TTL logic thresholds and noise immunity |
| 8 | Q0 | Register output A (LSB) - reflects stored bit after clock edge or parallel load |
| 9 | Q1 | Register output B - provides synchronized data for downstream latch or bus interface |
| 10 | Q2 | Register output C - used in multi-stage pipeline or feedback loop configurations |
| 11 | Q3 | Register output D (MSB) - delivers high-order bit for status reporting or arithmetic alignment |
| 12 | S1 | Mode control input A - selects shift direction or hold function with S0 |
| 13 | S0 | Mode control input B - combined with S1 to define register operation mode per truth table |
| 14 | VCC | +5 V power supply - must be decoupled locally to suppress switching noise in high-reliability systems |
| 15 | DSR | Data serial right input - feeds new bit into Q0 during right-shift mode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-bit universal shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN54LS195AJ | Identical logic function, pinout, and DC specs; same CDIP-16 package and SNPB finish; identical MIL-PRF-38535 Class B qualification level | No functional difference - direct form-fit-function replacement with identical test documentation traceability | Select SN54LS195AJ when sourcing from TI's commercial-grade 54-series line with identical screening but different part-numbering convention |
| SNJ54LS195AJ | Same electrical and mechanical specifications; differs only in manufacturer internal lot trace coding and procurement channel (TI's JAN-certified line) | Used interchangeably in DoD contracts requiring JAN designation; identical reliability testing and burn-in protocols | Choose SNJ54LS195AJ for programs requiring explicit JAN prefix in BOM and certificate of conformance |
Compared with M38510/30602BEA, SN54LS195AJ and SNJ54LS195AJ provide identical timing, voltage, and packaging behavior but differ in procurement lineage and documentation labeling-enabling seamless substitution where contract-specific nomenclature or certification path dictates part selection.

FAQ
What is the operating temperature range of the M38510/30602BEA?
The M38510/30602BEA is rated for operation from –55°C to +125°C, validated per MIL-PRF-38535 Class B requirements. This range supports deployment in jet engine compartments, satellite payloads, and underground command bunkers where ambient thermal extremes occur. The M38510/30602BEA maintains full logic functionality and timing specifications across this entire span without derating.
Is the M38510/30602BEA RoHS compliant?
No, the M38510/30602BEA uses SnPb (tin-lead) lead finish and is explicitly marked "No" for RoHS compliance in TI's packaging documentation. It is intended for legacy military and aerospace systems requiring proven solder joint reliability under thermal cycling and mechanical shock. The M38510/30602BEA is not suitable for new RoHS-only designs without waiver approval.
Does the M38510/30602BEA support left-shift and right-shift operations?
Yes, the M38510/30602BEA supports both left-shift and right-shift modes via its dual mode-control inputs S1 and S0. When S1=1 and S0=0, it performs right-shift using DSR; when S1=0 and S0=1, it performs left-shift using DSL. These functions are fully synchronous and edge-triggered by CLK. The M38510/30602BEA also supports hold and parallel-load modes within the same 4-bit register structure.
What is the package type and pin count of the M38510/30602BEA?
The M38510/30602BEA uses a 16-pin Ceramic Dual In-Line Package (CDIP-J), with 0.3-inch body width and 0.1-inch pin pitch. It is hermetically sealed and qualified to MIL-STD-883. The M38510/30602BEA's pinout matches industry-standard 54LS195 devices, enabling drop-in replacement in existing layouts without redesign.
How does the M38510/30602BEA differ from commercial LS195 devices?
The M38510/30602BEA differs from commercial LS195 variants in three key ways: it undergoes full MIL-PRF-38535 Class B screening (including burn-in and radiation lot acceptance testing), uses hermetic CDIP packaging instead of plastic DIP, and is characterized across –55°C to +125°C-not just 0°C to +70°C. The M38510/30602BEA retains identical logic behavior and pinout but meets higher reliability and environmental stress standards.
