General Description

The MAX4626/MAX4627/MAX4628 are low-on-resis-

tance, low-voltage, single-pole/single-throw (SPST)

analog switches that operate from a +1.8V to +5.5V sin-

gle 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

When powered from a +5V supply, the MAX4626/

MAX4627/MAX4628 offer 0.5

Ω max on-resistance

logic inputs are TTL compatible. These switches also

feature overcurrent protection to prevent device dam-

age 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 pack-

ages; the MAX4628 is available in a SOT23-6 package.
