General Description

The MAX4551/MAX4552/MAX4553 are quad, low-volt-

age, single-pole/single-throw (SPST) analog switches.

Each switch is protected against ±15kV electrostatic

discharge (ESD) shocks, without latchup or damage.

On-resistance (100Ω max) is matched between switch-

es to 4Ω max, and is flat (8Ω max) over the specified

signal range. Each switch can handle Rail-to-Rail

ana-

log signals. The off-leakage current is only 1nA at

+25°C and 10nA at +85°C.

The MAX4551 has four normally closed (NC) switches,

and the MAX4552 has four normally open (NO) switch-

es. The MAX4553 has two NC and two NO switches.

These CMOS switches can operate with dual power

supplies ranging from ±2V to ±6V or a single supply

between +2V and +12V. They are fully specified for sin-

gle +2.7V operation.

All digital inputs have +0.8V and +2.4V logic thresh-

olds, ensuring TTL/CMOS-logic compatibility when

using ±5V or a single +5V supply.

MAX4551/MAX4552/MAX4553 ±15kV ESD-Protected, Quad, Low-Voltage, SPST Analog Switches Applications Information MAX4551/MAX4552/MAX4553 ±15kV ESD Protection The MAX4551/MAX4552/MAX4553 are ±15kV ESD-protected according to IEC 1000-4-2 at their NC/NO pins. To accomplish this, bidirectional SCRs are included onchip between these pins and the GND pin. In normal operation, these SCRs are off and have negligible effect on the performance of the switches.
PAGE 9
±15kV ESD-Protected, Quad, Low-Voltage, SPST Analog Switches Overview The MAX4551/MAX4552/MAX4553 construction is typical of most CMOS analog switches. They have three supply pins: V+, V-, and GND. V+ and V- are used to drive the internal CMOS switches, and they set the limits of the analog voltage on any switch. Reverse ESDprotection diodes are internally connected between each analog-signal pin and both V+ and V-. If any analog signal exceeds V+ or V-, one of these diodes conducts.
