M38510/30609B2A

Shift Registers Overview

M38510/30609B2A is a military-grade 8-bit parallel-in serial-out shift register manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range from -55 °C to 125 °C. The component utilizes a 20-pin LCCC (FK) package with a ceramic body and tin-lead-free (SNPB) lead finish. It complies with MIL-M-38510 specifications for Class B microcircuits.

Shift Registers Feature Summary

• Provides eight-bit data storage with serial output capability
• Supports asynchronous clear functionality for immediate reset
• Features high-speed clock inputs for rapid data shifting

Shift Registers Applications

• Military communication systems requiring reliable data transmission
• Defense avionics equipment utilizing serial data processing
• Spacecraft telemetry control units

Shift Registers Procurement Notes

Verify the specific revision suffix against the latest Package Option Addendum, as availability varies between active production and NRND statuses. Confirm that the LCCC package variant matches the required footprint. Ensure procurement channels are authorized for QML certified components to maintain compliance with defense acquisition standards.

Shift Registers Selection Notes

Select this component when extended temperature operation below zero degrees Celsius is mandatory. Compare against commercial SN74LS166A variants if industrial grade suffices. Evaluate pin compatibility with existing CDIP or CFP footprints if transitioning from older military designs.

Shift Registers Part Context

This part belongs to the LS166A family of low-power Schottky TTL logic devices. It serves as the military specification equivalent to standard catalog parts, ensuring higher reliability and stricter manufacturing controls. The M38510 designation indicates adherence to Department of Defense microcircuit standards.
