Detailed Description
The MAX4744/MAX4744H/MAX4745/MAX4745H/
MAX4746H are low on-resistance, low-voltage, dual-
SPDT analog switches that operate from a +1.8V to
+5.5V single supply. These devices feature a negative
signal capability that allows signals as low as VCC -
5.5V to pass through without distortion.
The MAX4744/MAX4745 feature two digital control bits
to control each switch independently (see Table 1). The
MAX4744H/MAX4745H/MAX4746H have one control bit
to switch both switches and an enable input EN to put
the switches in a high-impedance mode. Driving EN
low takes the switches out of high impedance and CB0
controls both switches (see Table 2).
The MAX4744/MAX4744H have internal shunt resistors
on all NO and NC terminals, and the MAX4746H has
internal shunt resistors on NC terminals to suppress
click-and-pop sounds that can occur when switching
audio signals between precharged points.
Applications Information
Digital Control Inputs
The MAX4744/MAX4744H/MAX4745/MAX4745H/
MAX4746H logic inputs accept up to +5.5V, regardless
of supply voltage. For example, with a +3.3V supply,
CB0, CB1, CB2, and EN can be driven low to GND and
high to +5.5V, allowing for mixed logic levels in a sys-
tem. Driving CB0, CB1, CB2, and EN rail-to-rail mini-
mizes power consumption.
