This device is a low charge injection, 8-channel, high-voltage analog switch integrated circuit (IC) intended for use in applications requiring high voltage switching controlled by low voltage control signals, such as ultrasound imaging and printers.Input data is shifted into an 8-bit shift register which can then be retained in an 8-bit latch. To reduce any possible clock feed-through noise, Latch Enable Bar (LE) should be left high until all bits are clocked in. Using HVCMOS? technology, this switch combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals.These ICs are suitable for various combinations of high voltage supplies, e.g., VPP/VNN : +50V/-150V, or +100V/-100V.
