General Description
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 feedthrough 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. The HV203 has the same electrical specifications as the HV202, but it is packaged in the 28 lead plastic chip carrier with the pin configuration of the Supertex HV2216PJ. This IC is suitable for various combinations of high voltage supplies, e.g., VPP/VNN : +50V/-150V, or +100V/-100V.

1. The eight switches operate independently. 2. Serial data is clocked in on the L H transition CLK. 3. The switches go to a state retaining their present condition at the rising edge of LE. When LE is low the shift register data flows through the latch. 4. DOUT is high when switch 7 is on. 5. Shift register clocking has no effect on the switch states if LE is H. 6. The clear input overrides all other inputs.
