10 Application and Implementation

10.1 Application Information

The SNx4HC164 is an 8-bit shift register that can be used as a deserializer in order to reduce the number of GPIO's needed when driving multiple LED's. In order to correctly display the proper output in the LED's a sink MOSFET was added to prevent the LED's from lighting up until the correct data or the proper clock signal has been achieved.

10.2 Typical Application

10.2.1 Design Requirements

Ensure that the incoming clock rising edge meets the criteria in Recommended Operating Conditions.

10.2.2 Detailed Design Procedure

Ensure that input and output voltages do not exceed ratings in Absolute Maximum Ratings.

Input voltage threshold information can be found in Recommended Operating Conditions.

Detailed timing requirements can be found in Timing Requirements, TA = 25°C.
