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 2: All devices are 100% tested at TA = +70°C. Limits over the operating temperature range are guaranteed by design and
characterization.
Note 3: The analog signal input VCOM_ and VNO_ must satisfy VNN ≤ (VCOM_, VNO_) ≤ VPP, or remain unconnected during power-up
and power-down.
Note 4: Guaranteed by characterization; not production tested.

Low-Charge Injection, 16-Channel,
High-Voltage Analog Switches
The MAX14802/MAX14803/MAX14803A provide highvoltage switching on 16 channels for ultrasonic imaging
and printer applications. The devices utilize HVCMOS
process technology to provide 16 high-voltage lowcharge-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 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/MAX14803 are available in the
48-pin TQFP package and are specified for the commercial 0°C to +70°C temperature 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.

MAX14802/MAX14803/MAX14803A
Pin Description (continued)
MAX14802/MAX14803/MAX14803A
Low-Charge Injection, 16-Channel,
High-Voltage Analog Switches
Detailed Description
The MAX14802/MAX14803/MAX14803A provide highvoltage switching on 16 channels for ultrasound 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 16bit 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 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 and feature clamping diodes (at the COM_).
These clamping diodes provide overvoltage protection
against positive overshoot.
Analog Switch
The MAX14802/MAX14803/MAX14803A allow a peak-topeak analog signal range from VNN to the minimum of
either VNN + 200V or (VPP - 10V). Analog switch inputs
must be unconnected, or satisfy VNN ≤ (VCOM_, VNO_) ≤
VPP during power-up and power-down.
High-Voltage Supplies
The MAX14802/MAX14803/MAX14803A allow a wide
range of high-voltage supplies. The devices operate
with VNN from -160V to 0 and VPP from +40V to VNN +
250V. When VNN is connected to GND (single-supply
applications), the devices operate with V PP up to
+200V. The VPP and VNN high-voltage supplies are not
required to be symmetrical, but the voltage difference
(VPP - VNN) must not exceed 250V.
Bleed Resistors (MAX14803/MAX14803A)
The MAX14803/MAX14803A feature integrated 35kΩ
bleed resistors to discharge capacitive loads such as
piezoelectric transducers. Each analog switch terminal
is connected to GND with a bleed resistor.
Overvoltage Protection
The MAX14802/MAX14803/MAX14803A feature clamping diodes (at the COM_). These clamping diodes provide overvoltage protection against positive overshoot.
Serial Interface
The MAX14802/MAX14803/MAX14803A are controlled
by a serial interface with a 16-bit serial shift register
and transparent latch. Each of the 16 data bits controls
a single analog switch (Table 1). Data on DIN is
clocked with the most significant bit (MSB) first into the
shift register on the rising edge of CLK. Data is clocked
out of the shift register onto DOUT on the rising edge of
CLK. DOUT reflects the status of DIN, delayed by 16
clock cycles (Figures 1 and 2).
Latch Enable (LE)
Drive LE logic-low to change the contents of the latch
and update the state of the high-voltage switches
(Figure 2). Drive LE logic-high to freeze the contents of
the latch and prevent changes to the switch states. To
reduce noise due to clock feedthrough, drive LE logichigh while data is clocked into the shift register. After
the data shift register is loaded with valid data, pulse
LE logic-low to load the contents of the shift register
into the latch.
Latch Clear (CLR)
The MAX14802/MAX14803/MAX14803A feature a latch
clear input. Drive CLR logic-high to reset the contents
of the latch to zero and open all switches. CLR does
not affect the contents of the data shift register. Pulse
LE logic-low to reload the contents of the shift register
into the latch.
Power-On Reset
The MAX14802/MAX14803/MAX14803A feature a
power-on-reset circuit to ensure all switches are open
at power-on. The internal 16-bit serial shift register and
latch are set to zero on power-up.

The 16 switches operate independently.
Serial data is clocked in on the rising edge of CLK.
The switches go to a state retaining their present condition on the rising edge of LE. When LE is low, the shift register data
flows through the latch.
Note 8: DOUT is high when switch 15 is on.
Note 9: Shift register clocking has no effect on the switch states if LE is high.

Logic Levels
The MAX14802/MAX14803/MAX14803A digital interface inputs CLK, DIN, LE, and CLR operate on the VDD
supply voltage.
Daisy-Chaining Multiple Devices
Digital output DOUT is provided to allow the connection
of multiple MAX14802/MAX14803/MAX14803A devices
by daisy-chaining (Figure 3). Connect each DOUT to the
DIN of the subsequent device in the chain. Connect CLK,
LE, and CLR inputs of all devices, and drive LE logic-low
to update all devices simultaneously. Drive CLR high to
open all the switches simultaneously. Additional shift registers can be included anywhere in series with the
MAX14802/MAX14803/MAX14803A data chain.
Supply Sequencing and Bypassing
The MAX14802/MAX14803/MAX14803A do not require
special sequencing of the VDD, VPP, and VNN supply
voltages; however, analog switch inputs must be
unconnected, or satisfy VNN ≤ (VCOM_, VNO_) ≤ VPP
during power-up and power-down. Bypass VDD, VPP,
and VNN to GND with a 0.1µF ceramic capacitor as
close as possible to the device.
