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.

Note 1: Signals on NC, NO, or COM exceeding V+ or GND are clamped by internal diodes.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
