The UC1525B and UC1527B are enhanced versions of the previous generation of UC1525A and UC1527A devices. They are pin-for-pin compatible and direct replacements for the A versions in almost all applications. The table in this design note compares the two sets of devices. Significant improvements have been made in the 5.1 V reference voltage and the output drivers as itemized in the table.
