19-4484; Rev 0; 4/09 www.DataSheet4U.com Low-Charge Injection, 16-Channel, High-Voltage Analog Switches General Description The MAX14800–MAX14803 provide high-voltage switching on 16 channels for ultrasonic imaging and printer applications. The devices utilize HVCMOS process technology to provide 16 high-voltage lowcharge-injection SPST switches, controlled by a digital interface. Data is clocked into an internal 16-bit shift register and retained by a programmable latch with enable and clear inputs. A power-on reset function ensures that all switches are open on power-up. The MAX14800–MAX14803 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 +2.7V to +5.5V VDD supply.
