I/O Expanders and Level Translators

STMicroelectronics

ST’s Xpander family of general-purpose input/output port expanders are used to interface digital ASICs via a two-line bidirectional bus (I²C) . ST’s dual-supply level translators are used as interface between multi-voltage chipsets and system I/Os, ranging from 5.5 V down to 1.2 V.
