16-Channel (Two Banks of 8-Channel),
High-Voltage Analog Switches
The MAX14805/MAX14806 provide high-voltage switch­ing on 16 channels for ultrasonic imaging. Both devices are ideal for the following applications: banks selection in biplane or triplane ultrasound probes and relays replace­ment. The devices utilize 200V process technology to provide sixteen high-voltage, low-charge injection SPST switches, controlled by a digital interface.
The MAX14805/MAX14806’s output switches are con­figured as two sets of eight SPST analog switches. The switches are controlled by two input logic controls, DIN1 and DIN2 (respectively for switch 0 to 7 and switch 8 to 15). The MAX14806 features integrated 40kI bleed resistors on each switch terminal, which help to reduce voltage buildup in capacitive loads such as piezoelectric elements.
The MAX14805/MAX14806 operate with a wide range of high-voltage supplies, including VPP/VNN = +100V/-100V, +200V/0V, and +40V/-160V. The digital interface oper­ates from a separate VDD supply from +2.7V to +5.5V. Digital inputs DIN1, DIN2, and LE operate on the VDD supply voltage.
The MAX14805CCM+ is a drop-in replacement for the Supertex HV2631. The MAX14806CCM+ is a drop-in replacement for the Supertex HV2731. Both devices are available in the 48-pin, TQFP package and are specified for the extended -40NC to +85NC temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

16-Channel (Two Banks of 8-Channel), High-Voltage Analog Switches
Detailed Description
The MAX14805/MAX14806 provide high-voltage switch­ing on 16 channels for ultrasonic imaging. Both devices are ideal for the following applications: bank selection in biplane or triplane ultrasound probes and relays replace­ment in medical ultrasound systems. The devices utilize 200V process technology to provide 16 high-voltage, low-charge injection SPST switches, controlled by a digital interface.
The MAX14805/MAX14806’s output switches are con­figured as two sets of eight SPST analog switches. The switches are controlled by two input logic controls, DIN1 and DIN2 (respectively for switch 0 to 7 and switch 8 to 15). The MAX14806 features integrated 40kI bleed resistors on each switch terminal that help to reduce voltage buildup in capacitive loads such as piezoelectric elements.
The MAX14805/MAX14806 operate with a wide range of
MAX14805/MAX14806
high-voltage supplies, including VPP/VNN = +100V/-100V, +200V/0V and +40V/-160V. The digital interface oper­ates from a separate VDD supply from +2.7V to +5.5V. Digital inputs DIN1, DIN2, and LE operate on the VDD supply voltage.
The MAX14805CCM+ is a drop-in replacement for the Supertex HV2631. The MAX14806CCM+ is a drop-in replacement for the Supertex HV2731.
Analog Switch
The MAX14805/MAX14806 allow a peak-to-peak analog signal range from VNN to (V and power-down, all analog switch inputs (SW_) must be unconnected or satisfy VNN P V

High-Voltage Supplies
The MAX14805/MAX14806 allow a wide range of high­voltage supplies. The devices operate with VNN from
-160V to 0V and VPP from +40V to (VNN + 220V). When VNN is connected to GND (single-supply applications), the devices operate with VPP up to +200V. The VPP and VNN high-voltage supplies are not required to be sym­metrical, but the voltage difference (VPP - VNN) must not exceed 230V.
Bleed Resistors (MAX14806)
The MAX14806 features integrated 40kI bleed resis­tors to discharge capacitive loads such as piezoelectric transducers. Each analog switch terminal is connected to GND with a bleed resistor.
Data Input (DIN1/DIN2)
DIN1/DIN2 control the on/off state of the analog switches. DIN1 controls SW0–SW7 and DIN2 controls SW8–SW15 (see Table 1 and Figure 2). DIN1 and DIN2 operate on the VDD supply voltage.
Latch Enable (LE)
Drive LE logic-low to latch DIN1/DIN2 data input (see Figure 2). Drive LE logic-high to hold data. The LE input operates on the VDD supply voltage.
Applications Information
For medical ultrasound applications, see Figures 3 and 4.
Supply Sequencing and Bypassing
The MAX14805/MAX14806 do not require special sequencing of the VDD, VPP, and VNN supply voltages; however, analog switch inputs must be unconnected or satisfy VNN P V down. Bypass VDD, VPP, and VNN to GND with a 0.1FF ceramic capacitor as close as possible to the device.
