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 V
PP
/V
NN
= +100V/-100V, +200V/0V, or +40V/-160V. The digital
interface operates from a separate +2.7V to +5.5V V
DD
supply. Digital inputs DIN, CLK, LE, and CLR operate
on the V
DD
supply voltage.
The MAX14803/MAX14803A provide integrated 35kΩ
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.

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.
Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial
