CD4035 Shift Register Datasheet, Pinout, Features & Applications
Hello Everyone! Hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to CD4035.
The CD4035 is a shift register that is mainly used in counters, control circuits, and registers. It contains clocked signal serial chip that is a four-stage register. Synchronous Parallel inputs are provided to each stage and serial inputs are offered to the first stage via JK logic.
I suggest you read this post all the way through as I’ll detail the complete introduction to CD4035 covering datasheet, pinout, features, alternatives, and applications. Let’s jump right in.
Introduction to CD4035
- The CD4035 is a shift register that is a 16-pin device and is mainly used in control circuits, counters, and registers.
- It is a four-stage register that comes with synchronous parallel inputs provided to each stage and is available in 16-pin PDIP, GDIP, and PDSO packages.
- The CD4035 chip contains two 4-bit Parallel-In & Parallel-Out Shift Registers which project that it is used to receive (input) data parallel and can control 4 output pins in parallel.
- Simply put, it extracts data from four parallel inputs, and as a result, shifts them and then offers that data on four parallel outputs.
- It carries the clock input edge that is used for data shifting where data is shifted on every positive clock edge.
- This four-stage register stage comes with D Flip Flops in each stage that are connected with each other.
- This chip seems to be the right fit for the applications where microcontrollers don’t have enough GPIO pins to handle the number of outputs.
- Since this chip can operate as the data bit for LCD, CD4035 can be employed for interfacing LCD screens
- The frequency of this chip is 12MHz at Vdd = 10V and the propagation delay time is 500ns.
- While the operating voltage range is 3V to 18V and the operating temperature range is -55C to 125C.
