Universal Semiconductor, Inc. USH5022

The USH5022 is an 8-channel high voltage analog switch which utilizes Universal's Proprietary full oxide isolation process for switching high voltage analog signals. This device can be used in ultrasound imaging systems and other high voltage applications which requires flexible high voltage switching controlled by internal CMOS logic signals. The USH5022 combines high voltage bidirectional DMOS switches with low power COMS logic to provide efficient control of high voltage analog signals. Input data is shifted into an 8-bit latch. To minimize any clock feedthrough noise, Latch Enable Bar should be left high until all bits are clocked in. The CL signal is active high and resets all the eight latches.
