MAX14800, MAX14801, MAX14802,

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 low-charge-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: V_PP/V_NN = +100V/-100V, +200V/0V, and +40V/-160V. The digital interface operates from a separate +2.7V to +5.5V V_DD supply. Digital inputs DIN, CLK, active-low LE, and CLR operate on the VDD supply voltage.

The MAX14801/MAX14803 provide integrated 35kΩ bleed resistors on each switch terminal to discharge capacitive loads. The MAX14802/MAX14803 provide integrated clamping diodes for overvoltage protection against positive overshoot.

The MAX14800–MAX14803 are available in the 48-pin TQFP package. All devices are specified for the commercial 0°C to +70°C temperature range.
