Detailed Description
The MAX4760 quad double-pole/double-throw (DPDT)
and the MAX4761 octal single-pole/double-throw
(SPDT) analog switches operate from a single +1.8V to
+5.5V supply. These devices are fully specified for +3V
applications.
The MAX4760/MAX4761 have a guaranteed 3.5
(max)
on-resistance to switch data or audio signals. The low
25pF capacitance and 0.2ns change in skew makes
them ideal for data switching applications. The MAX4760
has 4 logic inputs to control two switches in pairs and the
MAX4761 has one logic control input and an enable input
(
EN
) to disable the switches.
Applications Information
Digital Control Inputs
The MAX4760/MAX4761 logic inputs accept up to
+5.5V regardless of the supply voltage. For example,
with a +3.3V supply, IN_ can be driven low to GND and
high to +5.5V, which allows mixed logic levels in a sys-
tem. Driving the control logic inputs rail-to-rail also mini-
mizes power consumption. For a +3V supply voltage,
the logic thresholds are 0.5V (low) and 1.4V (high).
For the MAX4761, drive
EN
low to enable. When
EN
is
high, COM_ is high impedance.
Analog Signal Levels
Analog signal inputs over the full voltage range (0V to V+)
are passed through the switch with minimal change in on-
resistance (see the
Typical Operating Characteristics
).
The switches are bidirectional so NO_, NC_, and COM_
can be either inputs or outputs.
Power-Supply Bypassing
Power-supply bypassing improves noise margin and
prevents switching noise from propagating from the V+
supply to other components. A 0.1μF capacitor connect-
ed from V+ to GND is adequate for most applications.
Power-Supply Sequencing
CMOS devices require proper power-supply sequenc-
ing. Always apply V+ before the analog signals, espe-
cially if the input signal is not current limited. If
sequencing is not possible, and the input signal is not
current limited to less than 20mA, add a small-signal
diode (Figure 1). Adding the diode reduces the analog
range to a diode drop (0.7V) below V+ and increases
the on-resistance slightly. The maximum supply voltage
must not exceed +6V at any time.
