CMOS 8-Stage Shift-and-Store Bus Register

CD4094BPWR General Description

The CD4094BPWR is a versatile and efficient CMOS 8-stage shift-and-store bus register that is ideal for a wide range of applications. Its 8-bit parallel input to serial output shift register with storage latches makes it a valuable tool for controlling digital components such as LEDs and displays. With an operating voltage range of 3V to 18V, this device is suitable for various industrial and consumer electronics applications. Its low power consumption and high noise immunity ensure reliable and energy-efficient operation, even in noisy environments. The 3-state outputs allow for easy cascading of multiple devices, making it perfect for driving LEDs, displays, and other digital components. Furthermore, the CD4094BPWR's compact TSSOP-16 package makes it easy to integrate into existing PCB designs, saving space and simplifying the manufacturing process. Whether it's for industrial control systems, lighting controls, or LED displays, the CD4094BPWR delivers exceptional performance and reliability

Key Features

  • 3-state parallel outputs for connection to common bus
