Low charge injection analog switch

This device is a low-charge-injection, eight-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.
