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

devices also have fast switching speeds (t

= 50ns

max, t

OFF

= 30ns max).

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

MAX4627/MAX4628 offer 0.5Ω max on-resistance

) with 0.1Ω max R

flatness, and their digital

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.
