MAX349 Maxim, MAX349 Datasheet - Page 2

• Manufacturer Part Number: MAX349
• Description: The MAX349/MAX350 are 8-channel and dual 4-channel serially controlled multiplexers (muxes)
• Manufacturer: Maxim

ABSOLUTE MAXIMUM RATINGS
Voltages Referenced to GND
Continuous Current into Any Terminal..............................±30mA
Peak Current, NO or COM
Serially Controlled, Low-Voltage,
8-Channel/Dual 4-Channel Multiplexers
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.
