MAX4643 Maxim, MAX4643 Datasheet - Page 2

• Manufacturer Part Number: MAX4643
• Description: The MAX4641/MAX4642/MAX4643 are monolithic, dual, single-pole/single-throw (SPST) switches that can operate from a single supply ranging from +1
• Manufacturer: Maxim

ABSOLUTE MAXIMUM RATINGS
(All Voltages Referenced to GND)
V+ .............................................................................-0.3V to +6V
IN_, COM_, NO_, NC_ (Note 1)....................-0.3V to (V+ + 0.3V)
Continuous Current (any terminal)....................................±20mA
Continuous Current (NO_, NC_, COM_)...........................±50mA
Peak Current (NO_, NC_, COM_, pulsed at 1ms,
High-Speed, Low-Voltage, 4Ω, Dual SPST
CMOS Analog Switches
Note 1: Signals on NO_, NC_, COM_, or IN_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to
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.
