CD74HC4094M

Shift Registers Overview

The CD74HC4094M is an 8-bit serial-in, parallel-out shift and store bus register manufactured by Texas Instruments. It integrates an 8-bit shift register, an 8-bit storage latch, and three-state parallel outputs within a single 16-SOIC package. The device operates on a supply voltage range of 2V to 6V and supports a wide operating temperature range from -55°C to 125°C. It belongs to the 74HC logic series, utilizing high-speed CMOS technology.

Shift Registers Feature Summary

• Serial-to-parallel data conversion with independent shift and storage stages
• Three-state parallel output buffers for bus sharing
• Dual serial outputs for flexible cascading configurations
• Wide voltage operation compatible with standard logic families

Shift Registers Applications

• Microcontroller I/O expansion systems
• LED display driver circuits
• Data acquisition input buffering
• Parallel output generation for peripheral control

Shift Registers Procurement Notes

Verify the specific suffix 'M' indicates the SOIC package variant when sourcing. Confirm RoHS compliance status as per current manufacturer documentation. Check for any recent Product Change Notifications regarding assembly or marking changes that may affect part identification.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with latched outputs is required in a surface-mount design. Ensure the system voltage falls within the 2V to 6V operational range. Consider the 74HC series speed and power characteristics relative to other logic families like HCT if TTL compatibility is needed.

Shift Registers Part Context

This component is part of the Texas Instruments 74HC family of high-speed CMOS logic devices. It serves as a fundamental building block for digital systems requiring serial data expansion. The device is functionally similar to other 8-bit shift registers but offers specific pinout and electrical characteristics defined by the HC series standards.
