CD74HC4094NSR

Shift Registers Overview

The CD74HC4094NSR is a high-speed CMOS logic device functioning as an 8-stage shift-and-store bus register with three-state outputs. Manufactured by Texas Instruments, it operates within a supply voltage range of 2 V to 6 V and supports clock frequencies up to 35 MHz at 5 V. The component utilizes standard 16-pin SOIC surface-mount packaging, ensuring compatibility with automated assembly processes while maintaining low power consumption characteristics inherent to the HC logic family.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion through an 8-stage shift register architecture
• Features latched storage capability for stable parallel output presentation
• Integrates three-state outputs to facilitate direct connection to system buses

Shift Registers Applications

• Parallel expansion of microcontroller I/O ports
• LED matrix display scanning systems
• Data buffering in digital communication interfaces

Shift Registers Procurement Notes

Verify the presence of the NSR suffix to confirm tape-and-reel packaging configuration suitable for automated pick-and-place manufacturing. Ensure the ordering part number matches the specific manufacturer designation to avoid confusion with non-three-state variants or alternative logic families. Confirm RoHS compliance status if required by environmental regulations.

Shift Registers Selection Notes

Select this component when design requirements necessitate serial input processing with simultaneous parallel access via latched outputs. The three-state feature allows multiple registers to share a common data bus without external isolation hardware. Consider the operating voltage range and package constraints during PCB layout planning.

Shift Registers Part Context

This device belongs to the Texas Instruments CD74HC series, representing high-speed CMOS technology compatible with standard TTL logic levels.
