Fairchild Semiconductor FXMA2102 high-performance configurable dual-voltage-supply translators provide bi-directional voltage translation over a wide range of input and output voltage levels. These Fairchild Semiconductor devices feature bi-directional interface between any two levels from 1.6V to 5.5V. Fairchild FXMA2102 voltage translators are intended for applications using the I²C bus interface. The input and output voltage levels are compatible with I²C device specification voltage levels. FXMA2102 voltage translators offer non-preferential power-up and either VCC may be powered up first. These Fairchild devices are available in an 8-terminal leadless MicroPak™ (1.6mm x 1.6mm) or Ultrathin MLP (1.2mm x 1.4mm).
Fairchild Semiconductor DB3 / DB3TG 150mW Bi-Directional Trigger Diodes
The Fairchild Semiconductor DB3 and DB3TG are 150mW bi-directional trigger diodes featuring low break-over current. Fairchild DB3 and DB3TG bi-directional trigger diodes have a typical break-over voltage (VBO) of 32V and come in a DO-35 package (JEDEC). The DB3 has a maximum break-out current of 100µA and the DB3TG 15µA. These Fairchild Semiconductor devices provide high reliability glass passivation ensuring parameter stability and protection against junction contamination.
