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 (t
max, t
When powered from a +5V supply, the MAX4624/
MAX4625 offer 1Ω max on-resistance (R
max R
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.
