Overview
The MAX4729/MAX4730 single-pole/double-throw (SPDT) switches operate from a single supply ranging from +1.8V to +5.5V. These switches provide low 3.5 Ω on-resistance (RON), as well as 0.45 Ω RON flatness with a +2.7V supply. These devices typically consume only 1nA of supply current, making them ideal for use in lowpower, portable applications. The MAX4729/MAX4730 feature low-leakage currents over the extended temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics.
The MAX4729/MAX4730 are available in small 6-pin SC70 and 6-pin μDFN packages. The MAX4729/ MAX4730 are offered in three pinout configurations to ease design. The MAX4729/MAX4730 are specified over the extended -40°C to +85°C temperature range.

MAX4729 Pinout
Package: SC70 (6-pin)
| Pin Number | Pin Name | Type | Description |
|---|---|---|---|
| 1 | IN | I | Signal Input |
| 2 | V+ | P | Positive Supply Voltage |
| 3 | GND | P | Ground |

Notes
- MAX4729 is a single-channel analog switch in SC70 package with 6 pins.
- The switch connects IN to COM when logic input is 0; connects NO to COM when logic input is 1 (see truth table in datasheet).
- NC (pin 4) should be left unconnected.
- Low on-resistance (RON) of 3.5 Ω at +2.7V supply.
- Supply voltage range: +1.8V to +5.5V.
Electrical Characteristics

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.
