1, Low-Voltage, Single-Supply
SPDT Analog Switches
General Description
The MAX4624/MAX4625 are low-on-resistance, low-
voltage single-pole/double-throw (SPDT) analog switch-
es that operate from a single +1.8V to +5.5V supply.
The MAX4624 has break-before-make switching; the
MAX4625 has make-before-break switching. These
devices also have fast switching speeds (tON = 50ns
max, tOFF = 50ns max).
When powered from a +5V supply, the MAX4624/
MAX4625 offer 1max on-resistance (RON), with 0.12
max RON matching and flatness. The digital logic
inputs are TTL compatible when using a single +5V
supply. These switches also feature overcurrent protec-
tion to prevent damage from short circuits and exces-
sive loads.
The MAX4624/MAX4625 are pin compatible with the
MAX4544 and are available in space-saving standard
6-pin SOT23 packages, as well as the 1.0mm high Thin
SOT package.

Note 1: Signals on NC, NO, and 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.
