Detailed Description
The MAX4780/MAX4784 are low 0.7
(at V+ = +2.7V)
on-resistance, low-voltage, quad 2:1 analog multiplexers/
demultiplexers that operate from a +1.6V to +4.2V single
supply. CMOS switch construction allows switching
analog signals that are within the supply voltage range
(GND to V+).
When powered from a +2.7V supply, the 0.7
RON
allows high continuous currents to be switched in a
variety of applications.
Applications Information
Proper power-supply sequencing is recommended for all
CMOS devices. Do not exceed the absolute maximum
ratings, because stresses beyond the listed ratings can
cause permanent damage to the devices. Always
sequence V+ on first, followed by NO_, NC_, or COM_.
Although it is not required, power-supply bypassing
improves noise margin and prevents switching noise
propagation from the V+ supply to other components. A
0.1F capacitor, connected from V+ to GND, is adequate
for most applications.
