This part is configured as a single-pole, single- Low On Resistance: 15 Typical throw sw itch and is optimized for isolating a high- Low Pow er Consumption: 1 A Maximum speed source, such as a DDR memory bus. The FSA1208 features an extremely low on capacitance 10 A Maximum ICCT over an Expanded Voltage (C ) of 6 pF Superior channel-to-channel crosstalk ON Range (V =2.3 V, V =4.3 V) IN CC minimizes interference. Wide -3 dB Bandw idth: > 400 MHz The FSA1208 contains special circuitry on the A & B Packaged in Space-Saving 20-Lead MLP pins that allow s the device to w ithstand an over-voltage (2.5 x 4.5 mm) condition. This device is also designed to minimize 7.5 kV ESD Rating >16 kV Pow er/GND ESD current consumption even w hen the control voltage Rating applied to the /OE pin is low er than the supply voltage (VCC). Applications include port isolation and sw itching Low C Capacitance: 2.5 pF Typical OFF in DDR memory modules, portable cell phones, PDAs, digital cameras, printers, and notebook computers.
