UM4717
4.5Ω 300MHz Bandwidth Dual SPDT Analog Switch
UM4717 CSP10 1.90×1.40
General Description
The UM4717 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. 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 switch is packaged in a chip-scale package (CSP), significantly reducing the required PC
board area. The chip occupies only a 1.90mm ×1.40mm area and has a 4×3 bump array with a
bump pitch of 0.50mm.

UM4717
Detailed Description
The UM4717 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)).
These 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 is designed to switch D+ and D- USB
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 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 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.
