High-Performance Power and Hall-Effect Sensor ICs
Product Replacement for the 58xx Family of Serial-Input
and Parallel-Input, Latched Sink Drivers 
Introduction
The 58xx family of serial-input and parallel-input, latched sink drivers has been a very successful product line for over 14 years. However, technological advancements in the fabrication process have lead to the design of a more efficient and more cost effective solution with added features: the 68xx family of serial-input and parallel-input, latched sink drivers. Although the 68xx family is advertised as a pin-for-pin replacement for the 58xx family, there are some important differences between them that could affect some applications.
