General Description
The Supertex HV238 is a 220V, 16-channel, high voltage analog switch integrated circuit (IC) with output bleed resistors (RINT). The output switches are configured as 2 sets of 8 single pole single throw analog switches. It is intended to be used in applications requiring high voltage switching controlled by low voltage control signals such as ultrasound imaging.

Features
► HVCMOS® technology for high performance
► 220V operating conditions
► Output on-resistance typically 22Ω
► Integrated bleed resistors on the outputs
► 5.0 and 12.0V CMOS logic compatibility
► Very low quiescent power dissipation (-10µA)
► -45dB min off isolation at 7.5MHz
► Low parasitic capacitance
► Excellent noise immunity
► Flexible operating supply voltages

Applications
► Medical ultrasound imaging
► Non-destructive evaluation
