These devices are low charge injection 8-channel high-voltage analog switch integrated circuits (ICs) 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, these switches combine high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals.
