MAX4644 Maxim, MAX4644 Datasheet - Page 6

• 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

High-Speed, Low-Voltage, 4 Ω ,
SPDT CMOS Analog Switch
(V+ = +5V or +3V, V
Note: The switches are bidirectional, which means that a signal can be passed through either side of the on switch. However,
