JM38510/30602B2A

Shift Registers Overview

The Texas Instruments JM38510/30602B2A is a military-grade shift register manufactured under the SN54LS195A specification. It features a 4-bit parallel-in or serial-in, serial-out architecture with bidirectional shifting capabilities and independent clock inputs for data entry and shifting operations. The device includes four D-type flip-flops with complementary outputs and an asynchronous clear function. It is housed in a 20-pin LCCC (FK) package designed for high-reliability applications. The component operates within a temperature range of -55°C to 125°C.

Shift Registers Feature Summary

• Supports both parallel and serial data input configurations for flexible system integration
• Features bidirectional shifting capability allowing data movement in either direction
• Includes an asynchronous clear input to reset all flip-flop states independently of the clock signal

Shift Registers Applications

• Military aerospace digital logic systems requiring radiation-hardened or high-reliability components
• Data storage registers in secure communication equipment
• Shift register circuits in industrial control systems operating in extreme environments

Shift Registers Procurement Notes

Verify that the specific ordering suffix matches the required package type, as this part number family includes CDIP variants. Confirm RoHS exemption status and lead finish specifications against project requirements. Ensure procurement channels are authorized to handle military-grade parts subject to specific quality assurance standards. Validate traceability documentation upon receipt.

Shift Registers Selection Notes

Select this component when a 4-bit shift register with bidirectional functionality and asynchronous clear is required for harsh environments. Compare against standard commercial LS series devices if military qualification and extended temperature ranges are not necessary. Consider pin compatibility with existing CDIP footprints if migrating from legacy designs.

Shift Registers Part Context

This part belongs to the SN54LSxxA series of low-power Schottky TTL logic devices. The JM38510 prefix indicates it is manufactured to MIL-M-38510 specifications for Class B microcircuits. It serves as a military version of the commercial SN54LS195A, offering identical logical functionality but with stricter manufacturing controls and environmental testing protocols.

Shift Registers FAQ

Does the JM38510/30602B2A support bidirectional shifting?

Yes, the device supports bidirectional shifting, allowing data to be shifted left or right based on control inputs.

What is the function of the asynchronous clear input?

The asynchronous clear input resets all four flip-flops to a low state immediately, regardless of the clock signal or data inputs.
