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.
