MAX14802/MAX14803/ Low-Charge Injection, 16-Channel, MAX14803A High-Voltage Analog Switches General Description Features The MAX14802/MAX14803/MAX14803A provide high- Integrated Overvoltage Protection voltage switching on 16 channels for ultrasonic imaging 20MHz Serial Interface (5V) and printer applications. The devices utilize HVCMOS HVCMOS Technology for High Performance process technology to provide 16 high-voltage low- charge-injection SPST switches, controlled by a digital Individually Programmable High-Voltage Analog Switches interface. Data is clocked into an internal 16-bit shift reg- ister and retained by a programmable latch with enable Very Low 5A (typ) Quiescent Current and clear inputs. A power-on reset function ensures that DC-to-20MHz Low-Voltage Analog Signal all switches are open on power-up. Frequency Range The MAX14802/MAX14803/MAX14803A operate with a 2.7V to 5.5V Logic Supply Voltage wide range of high-voltage supplies including V /V PP NN Low-Charge Injection, Low-Capacitance R Switches = +100V/-100V, +200V/0V, or +40V/-160V. The digital L interface operates from a separate +2.7V to +5.5V V DD -77dB (typ) Off-Isolation at 5MHz (R = 50) L supply. Digital inputs DIN, CLK, LE, and CLR operate on Daisy-Chainable Serial Interface the V supply voltage. DD Flexible High-Voltage Supplies (V - V = 250V) PP NN The MAX14803/MAX14803A provide integrated 35k bleed resistors on each switch terminal to discharge capacitive loads. The MAX14802/MAX14803/MAX14803A provide integrated clamping diodes for overvoltage pro- tection against positive overshoot. The MAX14802 is available in a 48-pin LQFP package and is specified for commercial 0C to +70C and extend- ed -40C to +85C temperature ranges. The MAX14803 is available in a 48-pin LQFP package Ordering Information/Selector Guide appear at end of data and is specified for the commercial 0C to +70C tem- sheet. perature range. The MAX14803A is available in the 110-bump wafer level package (WLP) and is specified at the -40C to +85C temperature range.
