The Supertex HV2631 is a 220V, 16-channel, high voltage analog switch integrated circuit (IC). The output switches are configured as 2 sets of 8 single pole, single throw, analog switches. The IC is intended to be used in applications requiring high voltage switching controlled by low voltage control signals, such as ultrasound imaging. The 2 sets of 8 analog switches are controlled by 2 input logic controls, DIN1 and DIN2. A logic high on DIN1 will turn on switches 0 to 7 and a logic high on DIN2 will turn on switches 8 to 15. Using HVCMOS technology, this device combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals.
