Applications Information
Logic Levels
The MAX4541
–
MAX4544 are TTL compatible when
powered from a single +5V supply. When powered
from other supply voltages, TTL compatibility is guar-
anteed and the logic inputs can be driven Rail-to-Rail
.
For example, with a +12V supply, IN1 and IN2 can be
driven low to 0 and high to 12V. With a +3.3V supply,
IN1 and IN2 should be driven low to 0 and high to
3.3V.
Driving IN1 and IN2 rail-to-rail minimizes power con-
sumption.
Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) can be switched with very little change in
on-resistance over the entire voltage range (see
Typical
Operating Characteristics
). All the switches are bidirec-
tional, so the NO_, NC_, and COM_ pins can be used
as either inputs or outputs.
