Product details
Overview
JM38510/30602B2A from Texas Instruments is a military-grade 4-bit universal shift register IC in LCCC-20 package, featuring TTL-compatible inputs, synchronous parallel load, serial shift-right capability, and operation across –55°C to +125°C. It implements standard 74LS195 functionality with enhanced reliability for aerospace and defense timing-critical control logic.
For engineers reviewing the JM38510/30602B2A datasheet, JM38510/30602B2A pinout, JM38510/30602B2A application, or JM38510/30602B2A equivalent, key selection considerations include its MIL-PRF-38535 Class B qualification, leaded SNPB finish, LCCC hermetic packaging, and direct functional alignment with SN54LS195AJ in high-reliability serial/parallel data handling.
Technical Context
This device implements a synchronous 4-bit universal shift register with parallel load, serial input (DSR), clock (CP), clear (CLR), and mode control (S0/S1). Its architecture supports hold, shift-right, parallel-load, and inhibit modes via two-mode-select inputs.
Designed for radiation-tolerant, high-stability environments, JM38510/30602B2A meets MIL-STD-883 test requirements and operates with TTL-level logic thresholds (VIH = 2.0 V min, VIL = 0.8 V max) and guaranteed propagation delays (tPLH/tPHL ≤ 35 ns at VCC = 5.0 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Function | 4-bit universal shift register with synchronous parallel load and serial shift-right |
| Operating Temperature | –55°C to +125°C, qualified for extended-range military and space applications |
| Supply Voltage | 4.5 V to 5.5 V, supporting stable operation under regulated 5-V rail conditions |
| Propagation Delay | ≤35 ns (max) at VCC = 5.0 V, enabling reliable timing in sub-30-MHz clock domains |

Pinout & Package
LCCC (FK) 20-pin leadless ceramic chip carrier, 8.89 mm × 8.89 mm body, 1.27 mm pitch, 2.03 mm max height, hermetically sealed with metallized perimeter terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Parallel Data Inputs (D0–D3) | Asynchronous parallel load inputs accepting TTL-level logic for register initialization |
| 5 | Serial Data Input (DSR) | Right-shift serial input; data shifted in on rising CP edge when S0=1, S1=0 |
| 6 | Mode Select S0 | Control bit selecting register function: combined with S1 defines hold/shift/load/inhibit |
| 7 | Mode Select S1 | Control bit paired with S0; S0=S1=1 enables parallel load on next CP rising edge |
| 8 | Clear (CLR) | Active-high asynchronous reset forcing all Q outputs low regardless of clock or mode state |
| 9, 10, 11, 13 | Outputs (Q0–Q3) | Registered complementary TTL outputs; Q0 = LSB, Q3 = MSB in shift-right sequence |
| 12 | Ground (GND) | Signal reference plane; must be connected to system ground with low-inductance path |
| 14 | Power (VCC) | +5 V supply rail; requires local 0.1 µF ceramic decoupling adjacent to pin |
| 15 | Clock (CP) | Positive-edge-triggered master clock; all synchronous operations occur on rising edge |
| 16–20 | No Connect (NC) | Internally unused terminals; must remain unconnected per TI design specification |

FAQ
What is the operating temperature range of the JM38510/30602B2A?
The JM38510/30602B2A is rated for continuous operation from –55°C to +125°C. This range is validated per MIL-STD-883 Test Method 1010 and confirmed in TI's official packaging addendum. The LCCC package and SNPB finish contribute to thermal stability across this full military specification range. JM38510/30602B2A maintains specified timing and logic thresholds throughout this interval without derating.
Is the JM38510/30602B2A RoHS compliant?
No, the JM38510/30602B2A uses a SnPb (63/37) lead finish and is explicitly marked "No" for RoHS compliance in TI's packaging documentation. It is intended for use in legacy aerospace, defense, and high-reliability systems where Pb-based soldering remains mandatory per J-STD-006 and MIL-STD-202. JM38510/30602B2A cannot be substituted with RoHS-compliant variants without redesign validation.
What package type does the JM38510/30602B2A use?
JM38510/30602B2A uses the LCCC (FK) package: a 20-pin leadless ceramic chip carrier measuring 8.89 mm × 8.89 mm with 1.27 mm pitch and maximum height of 2.03 mm. Per TI's generic package view and materials table, it is hermetically sealed and designed for surface-mount reflow or epoxy bonding. JM38510/30602B2A requires precise stencil and placement for reliable interconnection.
How does the JM38510/30602B2A differ from the SN54LS195AJ?
JM38510/30602B2A and SN54LS195AJ share identical logic function, AC/DC electrical specifications, and pinout-but differ in package (LCCC-20 vs. CDIP-16), qualification level (MIL-PRF-38535 Class B vs. MIL-STD-883), and mechanical form factor. JM38510/30602B2A includes full traceability, lot-specific test reports, and hermetic sealing. Both devices implement the same 74LS195 architecture.
Does the JM38510/30602B2A support parallel load and serial shift in the same cycle?
No-JM38510/30602B2A requires separate cycles: parallel load is enabled when S0=S1=1 and executed on the next rising CP edge; serial shift-right occurs when S0=1 and S1=0 on subsequent CP edges. The modes are mutually exclusive per clock cycle. JM38510/30602B2A does not support simultaneous load-and-shift; timing diagrams in TI's 74LS195 datasheet confirm this behavior.
