MAX4581 Maxim, MAX4581 Datasheet - Page 8

• Manufacturer Part Number: MAX4581
• Description: The MAX4581/MAX4582/MAX4583 are low-voltage, CMOS analog ICs configured as an 8-channel multiplexer (MAX4581), two 4-channel multiplexers (MAX4582), and three single-pole/double-throw (SPDT) switches (MAX4583)
• Manufacturer: Maxim

The MAX4581/MAX4582/MAX4583 construction is typi-
cal of most CMOS analog switches. They have three
Low-Voltage, CMOS Analog
Multiplexers/Switches
Note: Input and output pins are identical and interchangeable. Any may be considered an input or output; signals pass equally well
