Description
HV238 16-Channel High-Voltage Analog Switch with Bleed Resistors Features • 220V Maximum Operating Voltage • 22Ω Typical Output On-resistance • Integrated Bleed Resistors on the Outputs • 5V to 12V CMOS Logic Compatibility • –10 µA Low-quiescent Current Consumption • –45 dB Minimum Off Isolation at 7.5 MHz • Low Parasitic Capacitance • Excellent Noise Immunity • Flexible Operating Supply Voltages Applications • Medical Ultrasound Imaging • Non-destructive Evaluation General Description The HV238 is a 220V, 16-channel, high-voltage analog switch integrated circuit (IC) with output bleed resistors (RINT). The output switches are configured as two sets of eight 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. The two sets of eight analog switches are controlled by two input logic controls, DIN1 and DIN2. A logic high on DIN1 will turn on switches zero to seven and a logic high on DIN2 will turn on switches eight to 15. The bleed resistors significantly reduce voltage built up on capacitive loads, such as piezoelectric transducers connected to the outputs.
