M38510/30608BEA

Shift Registers Overview

M38510/30608BEA is a military-grade SN54LS165A parallel-load 8-bit shift register manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 25 MHz. The device features eight direct data inputs, gated clock functionality, and complementary outputs. It is housed in a 16-pin ceramic dual in-line package (CDIP) and is qualified for operation across an extended temperature range from -55 °C to 125 °C.

Shift Registers Feature Summary

• Provides parallel-to-serial data conversion capability through eight individual direct data inputs enabled by the shift/load control signal.
• Features gated clock inputs that allow one input to function as a clock-inhibit mechanism, enabling precise timing control.
• Includes diode-clamped inputs designed to minimize transmission-line effects and simplify system integration.

Shift Registers Applications

• Parallel-to-serial data conversion systems
• Digital signal processing applications requiring serial shifting
• Military and defense electronic equipment

Shift Registers Procurement Notes

Verify component authenticity against official manufacturer documentation before procurement. Confirm that the specific ordering suffix matches the required package type and qualification level. Ensure compliance with applicable military specifications and environmental standards relevant to the intended deployment environment.

Shift Registers Selection Notes

Select this component when designing systems requiring robust parallel-to-serial conversion under extreme environmental conditions. Consider its compatibility with low-power Schottky TTL logic families. Evaluate the necessity of its military-grade qualification and extended temperature range capabilities relative to standard commercial alternatives.

Shift Registers Part Context

This part belongs to the SN54LS165A family of parallel-load 8-bit shift registers produced by Texas Instruments. It adheres to MIL-M-38510 specifications, ensuring high reliability for aerospace and defense sectors. The device represents a specialized variant of the widely used LS165 architecture, tailored for stringent operational requirements.

Shift Registers Replacement Considerations

JM38510/30608BFA serves as a confirmed substitute offering identical functional characteristics but utilizes a ceramic flatpack (CFP) package instead of the CDIP configuration. Verify pinout compatibility and mechanical fit during replacement planning.
