General Description
|
The FSA1208 is a low-power, eight-port, high-speed switch.
This part is configured as a single-pole, single-throw 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.
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.
