The MAX4626/MAX4627/MAX4628 are low-on-resistance, low-voltage, single-pole/single-throw (SPST) analog switches that operate from a +1.8V to +5.5V single supply. The MAX4626 is normally open (NO), and the MAX4627 is normally closed (NC). The MAX4628 is normally open (NO) and has two control inputs. These devices also have fast switching speeds (tON = 50ns max, tOFF = 30ns max).

When powered from a +5V supply, the MAX4626/ MAX4627/MAX4628 offer 0.5Ω max on-resistance (RON) with 0.1Ω max RON flatness, and their digital logic inputs are TTL compatible. These switches also feature overcurrent protection to prevent device damage from short circuits and excessive loads.

The MAX4626 is pin compatible with the MAX4514, and the MAX4627 is pin compatible with the MAX4515. The MAX4626/MAX4627 are available in SOT23-5 packages; the MAX4628 is available in a SOT23-6 package.
