MAX4628

0.5Ω, Low-Voltage, Single-Supply SPST Analog Switches

Maxim Integrated 

MAX4626/MAX4627/

MAX4628

0.5Ω, Low-Voltage, Single-Supply

SPST Analog Switches

General Description

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 over-

current 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.
