CD74HC4094E

Shift Registers Overview

The CD74HC4094E is an 8-bit shift-and-store bus register manufactured by Texas Instruments. It integrates an 8-stage shift register and an 8-bit storage register with three-state parallel outputs. The device operates on a supply voltage range of 2V to 6V and supports surface mount installation in a 16-SOIC package. It functions as a serial-to-parallel converter, allowing data input via a serial line and output via eight parallel lines.

Shift Registers Feature Summary

• Serial-to-parallel conversion capability using a single serial data input and clock signal.
• Three-state parallel outputs controlled by an output enable pin for bus sharing.
• Separate clock inputs for the shift register and storage register to prevent output glitches during data shifting.

Shift Registers Applications

• I/O expansion for microcontroller systems
• Driving LED displays or indicator arrays
• Control of peripheral devices requiring serial data input

Shift Registers Procurement Notes

Verify the specific suffix 'E' against the manufacturer's current datasheet to confirm package details and compliance status. Ensure the ordering part number matches the required tape and reel or cut tape configuration. Confirm RoHS3 compliance and moisture sensitivity level requirements for your assembly process before finalizing procurement.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel interface is required with tri-state output control. It is suitable for applications needing glitch-free data updates due to separate shift and store clocks. Verify that the 2V to 6V operating voltage range aligns with the system power supply and logic levels.

Shift Registers Part Context

This component belongs to the Texas Instruments 74HC series of high-speed CMOS logic devices. It is functionally compatible with other 74HC4094 variants from different manufacturers, such as NXP or STMicroelectronics, provided voltage and timing specifications are met. The device is designed for general-purpose digital logic applications.

Shift Registers Replacement Considerations

Compatible substitutes include CD74HC4094M96 and CD74HC4094PWR from Texas Instruments. Other manufacturers offer equivalent parts under the 74HC4094 designation, such as HEF4094B from NXP. Verify pinout and electrical characteristics before substitution.
