Si9711CY Vishay Siliconix Si9711 PC Card (PCMCIA) Interface Switch FEATURES • Single SO-16 Package • CMOS Inputs with Hysteresis • Extremely Low RON • Reverse Blocking Switches • HiZ Outputs in the Off-State • Low Power Consumption • Safe Power-Up DESCRIPTION The Si9711CY is a monolithic switch designed to meet the needs of the PC Card interface. The inputs are fully CMOS compatible and incorporate all the level shift and interface required to be driven by any CMOS driver. The external inputs can be driven to 3.3-V or 5-V by setting VL at the appropriate level. The switches are low RON and can carry the maximum currents found on the PC Card interface. The 5-V and 3.3-V switches do not have the parasitic diode found in vertical DMOS power switches. Low RON is achieved by using MOSFETs driven off the +12-VIN input. All level shifting is built into the Si9711CY. The Si9711CY is packaged in an SO-16 package and is rated over the commercial temperature range 0 to 70°C.
