MAX4644 Maxim, MAX4644 Datasheet - Page 2

• Manufacturer Part Number: MAX4644
• Description: The MAX4644 is a single-pole/double-throw (SPDT) switch that operates from a single supply ranging from +1
• Manufacturer: Maxim

(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, and COM) .........................±50mA
Peak Current (NO, NC, and COM, pulsed at 1ms,
High-Speed, Low-Voltage, 4 Ω ,
SPDT CMOS Analog Switch
ABSOLUTE MAXIMUM RATINGS
Note 1: Signals on NO, NC, COM, or IN exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to maximum
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.
