Description

This device HV20420 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.

HV20420 is suitable for various combinations of high voltage supplies, e.g., VPP/VNN : +50V/150V, or +100V/100V.

The specifications for the HV20420 and HV206 are identical except that the pinouts in the 28-lead plastic chip carrier are different.
