Low-Charge Injection, 16-Channel,

High-Voltage Analog Switches

–MAX14803

General Description

Features

♦ Integrated Overvoltage Protection (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

enable and clear inputs. A power-on reset function

ensures that all switches are open on power-up.

MAX14803)

♦ 20MHz Serial Interface (5V)

♦ HVCMOS Technology for High Performance

♦ Individually Programmable High-Voltage Analog

Switches

The MAX14800–MAX14803 operate with a wide range

♦ Very Low 5µA (typ) Quiescent Current

of high-voltage supplies including: V /V

= +100V/

PP NN

-100V, +200V/0V, and +40V/-160V. The digital interface

operates from a separate +2.7V to +5.5V V supply.

♦ DC-to-20MHz Low-Voltage Analog Signal

Frequency Range

Digital inputs DIN, CLK, LE, and CLR operate on the

supply voltage.

♦ 2.7V to 5.5V Logic 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.

♦ Low-Charge Injection, Low-Capacitance R

Switches

♦ -77dB (typ) Off-Isolation at 5MHz (R = 50Ω)

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.

♦ Daisy-Chainable Serial Interface

♦ Flexible High-Voltage Supplies (V - V

= 250V)
