FSA1208
Low-Power, Eight-Port, High-Speed Isolation Switch
Features
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.
Low On Capacitance: 6pF Typical
Low On Resistance: 15Ω Typical
Low Power Consumption: 1μA Maximum
10μA Maximum ICCT over an Expanded Voltage
Range (VIN=2.3V, VCC=4.3V)
Wide -3db Bandwidth: > 400MHz
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.
Packaged in Space-Saving 20-Lead MLP
(2.5x4.5mm)
8kV ESD Rating; >16kV Power/GND ESD Rating
Low COFF Capacitance: 2.5pF Typical
Applications
DIMM DDR Memory
