MAX4643 Maxim, MAX4643 Datasheet - Page 6

• 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

High-Speed, Low-Voltage, 4Ω, Dual SPST
CMOS Analog Switches
(V+ = +5V or +3V, V
Note: NO_, NC_, and COM_ pins are identical and interchangeable. Signals can be passed through either side of these bidirectional
switches. However, the typical off-capacitances differ, as shown in the Electrical Characteristics.
