16-Channel (Two Banks of 8-Channel),
High-Voltage Analog Switches
General Description
Features
S HVCMOS Technology for High Performance
The MAX14805/MAX14806 provide high-voltage switch-
ing on 16 channels for ultrasonic imaging. Both devices
are ideal for the following applications: banks selection in
biplane or triplane ultrasound probes and relays replace-
ment. The devices utilize 200V process technology to
provide sixteen high-voltage, low-charge injection SPST
switches, controlled by a digital interface.
S Two Sets of 8-Channel SPST High-Voltage Analog
Switches
S DC to 20MHz Low-Voltage Analog Signal
Frequency Range
S +2.7V to +5.5V Logic Supply Voltage
S Ultra-Low (0.1µA) (typ) Quiescent Current
The MAX14805/MAX14806’s output switches are con-
figured as two sets of eight SPST analog switches. The
switches are controlled by two input logic controls, DIN1
and DIN2 (respectively for switch 0 to 7 and switch 8
to 15). The MAX14806 features integrated 40kI bleed
resistors on each switch terminal, which help to reduce
voltage buildup in capacitive loads such as piezoelectric
elements.
S Low-Charge Injection, Low-Capacitance 20I
Switches
S -77dB (typ) Off-Isolation at 5MHz (50I)
S Flexible, High-Voltage Supplies (V

Applications
The MAX14805/MAX14806 operate with a wide range of
Medical Ultrasound Imaging
Nondestructive Test (NDT)
high-voltage supplies, including V /V = +100V/-100V,
PP NN
+200V/0V, and +40V/-160V. The digital interface oper-
ates from a separate V
supply from +2.7V to +5.5V.
DD
Digital inputs DIN1, DIN2, and LE operate on the V
DD
supply voltage.
The MAX14805CCM+ is a drop-in replacement for the
Supertex HV2631. The MAX14806CCM+ is a drop-in
replacement for the Supertex HV2731. Both devices are
available in the 48-pin, TQFP package and are specified
for the extended -40NC to +85NC 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.

resistors on each switch terminal that help to reduce
voltage buildup in capacitive loads such as piezoelectric
elements.
The MAX14806 features integrated 40kI bleed resis-
tors to discharge capacitive loads such as piezoelectric
transducers. Each analog switch terminal is connected
to GND with a bleed resistor.
Data Input (DIN1/DIN2)
DIN1/DIN2 control the on/off state of the analog switches.
DIN1 controls SW0–SW7 and DIN2 controls SW8–SW15
