DESCRIPTION/ORDERING INFORMATION
The TS2DDR2811 is a 8-channel single-pole single-throw (SPST) signal switch capable of switching signals with
bandwidth in excess of 1 GHz. The device includes a select pin (SEL) that is used to select any 1 of the 8
channel inputs. This select pin controls the data path of the SPST switch. The device provides a low and flat
ON-state resistance (r_ON) and an excellent ON-state resistance match. Low input/output capacitance, high
bandwidth, low skew, and low crosstalk among channels make this device suitable for various high-bandwidth
applications, such as DDR2, 10/100/1000 Base-T, audio, and video.
