SM5839A
High-Speed Variable-Length Shift Register
OVERVIEW
The SM5839A is an 8-bit variable-length shift
resister. The input pins can be configured to function
as a 2 to 128-step shift resister. The shift clock has a
maximum frequency of 54 MHz, making it ideal for
high-speed digital signal processing.
