Description

The Supertex HV230 and HV232 are low charge injection 8-channel high-voltage analog switch integrated circuits (ICs) with bleed resistors. These devices can be used in applications requiring high voltage switching controlled by low voltage control signals, such as ultrasound imaging and printers. The bleed resistors eliminate voltage built up on capacitive loads such as piezoelectric transducers. 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 HV230 combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals.

HV230 are suitable for various combinations of high voltage supplies, e.g., VPP/VNN : +50V/150V, or +100V/100V.
