CD4015BE CMOS Dual 4-Stage Static Shift Register IC

The CD4015 designed as a Dual 4-bit Serial In – Parallel Out Shift Register. It offers a wide operating voltage up to 18V, hence can be used in high voltage applications. The IC is commonly used as I/O expander along with a microcontroller to control multiple outputs like LED, LCD display, etc.

These 4-bit serial In – Parallel Out Shift Registers take (input) data serially and control four parallel output pins. This is useful when our MCU/MPU does not have enough GPIO pins to control the needed number of outputs. Furthermore, it is frequently utilised in projects requiring the control of a large number of LEDs via a microcontroller. It’s also utilised to connect LCD screens because it serves as the data bit for LCD displays.

Due to the fact that the IC has two such Shift Registers in one package. In addition, it can be used to control two outputs in parallel independently. Typically used to manage a 7-Segment display or drive two LCDs in 4-bit mode. So, if you’re seeking for a solution to increase the I/O capability of your MCU, this IC could be a good fit.
