Dual, 5 Analog Switches
General Description Features
The MAX4621/MAX4622/MAX4623 are precision, dual, Low On-Resistance: 3 (typ), 5 (max)
high-speed analog switches. The single-pole/single-

also offer low leakage (<500pA at +25C, <5nA at
+85C) and fast switching times (turn-on time <250ns,

turn-off time <200ns).
Rail-to-Rail Analog Signal Handling Capability
These analog switches are ideal in low-distortion appli-

Note 1: Signals on NO_, NC_, or COM_ exceeding V+ or V- are clamped by internal diodes. Limit forward-diode current to maxi-
mum current rating.
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.
