Dual SPST Analog Switches in UCSP

_______________________________________________________________________________________
Detailed Description
The MAX4721/MAX4722/MAX4723 dual SPST analog
switches operate from a single +1.8V to +5.5V supply.
The MAX4721/MAX4722/MAX4723 offer excellent AC
characteristics, <0.5nA leakage current, less than 2ms
differential skew, and 15pF on-channel capacitance. All
of these devices are CMOS-logic compatible with rail-
to-rail signal handling capability.
The MAX4721/MAX4722/MAX4723 are USB-compliant
switches that provide 4.5
(max) on-resistance, and
15pF on-channel capacitance to maintain signal integri-
ty. At 12Mbps (USB full-speed data rate specification)
the MAX4721/MAX4722/MAX4723 introduce less than
2ns propagation delay between input and output sig-
nals and less than 0.5ns change in skew for the output
signals (see Figure 3 for more details).
The MAX4721 has two normally open (NO) switches, the
MAX4722 has two normally closed (NC) switches, and
the MAX4723 has one NO switch and one NC switch.
Applications Information
Digital Control Inputs
The MAX4721/MAX4722/MAX4723 logic inputs accept
up to +5.5V regardless of supply voltage. For example,
with a +3.3V supply, IN_ can be driven low to GND and
high to +5.5V allowing for mixing of logic levels in a
system. Driving the control logic inputs rail-to-rail mini-
mizes power consumption. For a +3.0V supply voltage,
the logic thresholds are 0.5V (low) and 1.4V (high); for
a +5V supply voltage, the logic thresholds are 0.8V
(low) and 2.0V (high).
Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) are passed with very little change in on-resis-
tance (see the
Typical Operating Characteristics
). The
switches are bidirectional, so the NO_, NC_, and COM_
pins can be either inputs or outputs.
