General Description
The MAX4599 single-pole/double-throw (SPDT) switch operates from a +2.0V to +5.5V single supply. It offers 60Ω max on-resistance (RON) at +5V and fast switching times (tON= 30ns max, t
OFF
= 25ns max).
The MAX4599 features excellent R
ON
flatness (4Ω max) and matching (1Ω max) between channels. This device also offers 5pC max charge injection.
The MAX4599 is available in tiny 6-pin SC70, µDFN, and SOT23 packages.

Typical Operating Characteristics
(TA = +25°C, unless otherwise noted.)
Applications Information
Analog Signal Levels
Analog signals can range over the supply voltage (V+ to GND) with on-resistance changing very little over the entire range (see Typical Operating Characteristics).
The MAX4599 is bidirectional, so the NO, NC, and COM pins can be used either as inputs or outputs.
Power-Supply Sequencing and
Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals or logic inputs, especially if the analog or logic signals are not current limited. If this sequenc­ing is not possible, and if the analog or logic inputs are not current limited to < 20mA, add a small-signal diode (D1) as shown in Figure 1. If the analog signal can dip below GND, add D2. Adding protection diodes
reduces the analog signal range to a diode drop (about
0.7V) below V+ for D1 or to a diode drop above ground for D2. The addition of diodes does not affect leakage. On-resistance increases by a small amount at low sup­ply voltages. Maximum supply voltage (V+) must not exceed 6V.
Protection diodes D1 and D2 also protect against some overvoltage situations. A fault voltage up to the absolute maximum rating at an analog signal input does not damage the device, even if the supply voltage is below the signal voltage.
