This device offers ultralow on resistance of less than.85 Ω over the full temperature range. The is fully specified for 3.3 V, 2.5 V, and.8 V supply operation. Each switch conducts equally well in both directions when on, and has an input signal range that extends to the supplies. The exhibits break-before-make switching action. The low on resistance of the makes this device ideal for audio switching. In addition, a data rate of 8 Mbps makes the device suitable for USB low speed (.5 Mbps) and full speed (2 Mbps) data switching. The is available in a.3 mm.6 mm, -lead mini LFCSP package.
