SN54HC194J

Shift Registers Overview

The SN54HC194J is a military-grade, high-speed CMOS octal universal shift register manufactured by Texas Instruments. It features two independent four-bit shift registers with parallel and serial input capabilities, supporting bidirectional shifting. The device operates within a wide temperature range of -55°C to 125°C and utilizes a 16-pin ceramic dual in-line package (CDIP). Designed for robust performance in harsh environments, it provides versatile data handling functions including hold, clear, and right/left shift modes.

Shift Registers Feature Summary

• Military-grade reliability with extended temperature operation from -55°C to 125°C
• High-speed CMOS technology ensuring low power consumption and fast switching speeds
• Bidirectional shifting capability allowing data movement in both left and right directions
• Universal functionality supporting parallel load, serial shift, and data hold operations

Shift Registers Applications

• Military communication systems requiring reliable data transmission
• Avionics control units operating in extreme environmental conditions
• Industrial automation controllers needing robust signal processing
• Spacecraft telemetry systems demanding high radiation tolerance and stability

Shift Registers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. Ensure the component meets all military specifications required for your application. Check for lead-free compliance status if applicable to your manufacturing process. Confirm availability through authorized distributors as this is a specialized military-grade part. Validate that the ceramic DIP package matches your board design requirements.

Shift Registers Selection Notes

Select the SN54HC194J when military-grade reliability and wide temperature operation are critical. Consider this part for applications requiring bidirectional data shifting in harsh environments. Compare against standard commercial grades if cost is a primary constraint but verify temperature limits. Ensure the ceramic package fits your assembly constraints compared to plastic alternatives.

Shift Registers Part Context

This component belongs to the SN54HC series of high-speed CMOS logic devices. The 'SN' prefix indicates a Texas Instruments product, while '54' denotes the military temperature range. The 'HC' signifies high-speed CMOS technology, and '194' identifies the universal shift register function. The 'J' suffix typically refers to the ceramic dual in-line package variant.

Shift Registers Replacement Considerations

Consider the SN54HC194N for plastic DIP packaging if military temperature ratings are not required. Verify pin compatibility before substituting with other universal shift registers. Ensure any replacement maintains the same voltage and current specifications.
