General Description
The MAX14802/MAX14803/MAX14803A 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 MAX14802/MAX14803/MAX14803A operate with a
wide range of high-voltage supplies including VPP/VNN
= +100V/-100V, +200V/0V, or +40V/-160V. The digital
interface operates from a separate +2.7V to +5.5V VDD
supply. Digital inputs DIN, CLK, LE, and CLR operate
on the VDD supply voltage.
The MAX14803/MAX14803A provide integrated 35k
Ω
bleed resistors on each switch terminal to discharge
capacitive
loads.
The
MAX14802/MAX14803/
MAX14803A provide integrated clamping diodes for
overvoltage protection against positive overshoot.
The MAX14802 is available in a 48-pin TQFP package
and is specified for commercial 0°C to +70°C and
extended -40°C to +85°C temperature ranges.
The MAX14803 is available in a 48-pin TQFP package
and is specified for the commercial 0°C to +70°C tem-
perature range.
The MAX14803A is available in the 110-bump wafer level
package (WLP) and is specified at the -40°C to +85°C
temperature range.
