Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground.


Description

The Supertex HV2731 is a 220V, 16-channel, high voltage, analog switch integrated circuit (IC) with output bleed resistors (RINT ). The output switches are con gured as 2 sets of 8 single pole, single throw analog switches. The HV2731 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. The bleed resistors help to signi cantly reduce voltage built up on capacitive loads such as piezoelectric transducers connected to the outputs.

Using HVCMOS®  technology, this device HV2731 combines high voltage bilateral DMOS switches and low power CMOS logic to provide ef cient control of high voltage analog signals.
