MAX4717/MAX4718
Detailed Description
The MAX4717/MAX4718 high-speed, low-voltage, low on-
resistance (RON), dual SPDT analog switches operate
from a single +1.8V to +5.5V supply. The switches feature
break-before-make switching operation and fast switch-
ing speeds (tON = 80ns (max), tOFF = 40ns (max)).
These switches have low 15pF on-channel capaci-
tance, which allows for 12Mbps switching of the data
signals for USB 1.0/1.1 applications. The MAX4717 is
designed to switch D+ and D- USB signals with a guar-
anteed skew of less than 2ns (see Figure 4) as mea-
sured from 50% of the input signal to 50% of the output
signal.
Applications Information
Digital Control Inputs
The MAX4717/MAX4718 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 minimizes
power consumption. For a +3V 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
The on-resistance of the MAX4717/MAX4718 changes
very little for analog input signals across the entire supply
voltage range (see the Typical Operating Characteristics).
The switches are bidirectional, so the NO_, NC_, and
COM_ pins can be either inputs or outputs.
Power-Supply Sequencing and
Overvoltage Protection
Caution: Do not exceed the absolute maximum rat-
ings because stresses beyond the listed ratings
may cause permanent damage to the device.
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V+ before applying
analog signals, especially if the analog signal is not
current-limited.
