UM4717/UM4717Q
4.5Ω 300MHz Bandwidth Dual SPDT Analog Switch
UM4717 CSP10 1.90×1.40
UM4717Q QFN10 1.80×1.40
General Description
The UM4717/UM4717Q low-voltage, low on-resistance (RON), dual single-pole/double-throw
(SPDT) analog switch operates from a single +1.8V to +5.5V supply. The device is designed for
USB 1.1/2.0 and audio switching applications.
The UM4717 features two 4.5Ω RON(max) SPDT switches with 1.2Ω flatness and 0.3Ω matching
between channels, while the UM4717Q features two 6Ω RON(max) SPDT switches with 1.8Ω
flatness and 0.6Ω matching between channels. The switch offers break-before-make switching
(1ns) with tON<80ns and tOFF<40ns at +2.7V. The digital logic inputs are +1.8V logic compatible
with a +2.7V to +3.6V supply.
The UM4717 is packaged in a chip-scale package (CSP), occupies only a 1.90mm ×1.40mm area
and has a 4×3 bump array with a bump pitch of 0.50mm. The UM4717Q is packaged in a 1.80mm
×1.40mm QFN10 package, both significantly reducing the required PC board area.

UM4717/UM4717Q
Detailed Description
The UM4717/UM4717Q high-speed, low-voltage, low on-resistance (RON), dual SPDT analog
switch operates from a single +1.8V to +5.5V supply. The switch features break-before-make
switching operation and fast switching speeds (tON=80ns (max), tOFF=40ns (max)).
The switch has low 15pF on-channel capacitance, which allows for 12Mbps switching of the data
signals for USB 1.0/1.1 applications. The UM4717/UM4717Q is designed to switch D+ and DUSB signals with a guaranteed skew of less than 2ns (see Figure 4) as measured from 50% of the
input signal to 50% of the output signal.
Applications Information
Digital Control Inputs
The UM4717/UM4717Q 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 UM4717/UM4717Q 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 Over-Voltage Protection
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.
