Description
The PI5A4624/PI5A4625 is an improved, direct replacement for the
MAX4624/MAX4625 single-pole, double-throw (SPDT) analog
switch. Improved specifications include a low maximum On-resis-
tance of 1-ohm and fast switching times (t
ON
= 50ns max., t
OFF
= 50
max.) with 5V supply operation. With a 2.5V supply, resistance is a
low 4-ohm max.
Specifications are given for 1.8V, 2.5V, 3.3V and 5V power supply
operation. Operating voltage range is +1.8V to +5.5V.
To minimize PC board area use, the PI5A4624/ PI5A4625 is available
in a compact 6-pin SOT-23 package.
