Profile: STMicroelectronics produces a diverse range of devices, ranging from single transistors to microprocessors. Our product line includes amplifiers & comparators, diodes, embedded microprocessors, evaluation tools, signal switches, microcontrollers, protection devices, and transistors. Our DC-DC converters are used in numerous automotive functions. ST offers a selection of Schottky diodes qualified to the AEC-Q101 standard. These dedicated products are guaranteed in operation at a junction temperature as low as -40°C, and as high as +150 °C. The extension Y is used in the part number to identify the automotive version for a given rectifier. Our multichannel clock distribution circuits do not need any coupling capacitor at the input, have a very low standby current, and an ultra-low phase noise. By distributing a single master clock to multiple clock domains, designers eliminate multiple individual clock sources for circuits supporting GSM, Bluetooth, WLAN, WiMAX or other RF communications, as well as in set-top-box applications.
