ADVANCE INFORMATION --CONFIDENTIAL & PROPRIETARY -- DO NOT DISTRIBUTE FSA1208 Low-Power, Eight-Port, High-Speed Isolation Switch Features Description Low On Capacitance: 6pF Typical The FSA1208 is a low-power, eight-port, high-speed switch. This part is configured as a single-pole, singlethrow switch and is optimized for isolating a high-speed source, such as a DDR memory bus. The FSA1208 features an extremely low on capacitance (CON) of 6pF. Superior channel-to-channel crosstalk minimizes interference. Wide -3db Bandwidth: > 400MHz 8kV ESD Rating; >16kV Power/GND ESD Rating Low On Resistance: 15 Typical Low Power Consumption: 1A Maximum 10A Maximum ICCT over an Expanded Voltage Range (VIN=2.3V, VCC=4.3V) The FSA1208 contains special circuitry on the A & B pins that allows the device to withstand an over-voltage condition. This device is also designed to minimize current consumption even when the control voltage applied to the /OE pin is lower than the supply voltage (VCC). Applications include port isolation and switching in DDR memory modules, portable cell phones, PDAs, digital cameras, printers, and notebook computers.
