0.5Ω, Low-Voltage, Single-Supply
SPST Analog Switches
General Description
Features
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

logic inputs are TTL compatible. These switches also
feature overcurrent protection to prevent device dam-
age from short circuits and excessive loads.
ꢀ TTL-Logic Compatible at +5V
ꢀ Pin Compatible with MAX4514 (MAX4626)
Pin Compatible with MAX4515 (MAX4627)
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.
