http://www.union-ic.com Rev.02 Sep.2013 1 0 / 1 4 UM4258Q Detailed Description The UM4258Q high-speed, low-voltage, low on-resistance (R ON), dual SPDT analog switch operates from a single +1.8V to +5.5V supply. Th e 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 12M bps switching of the data signals for USB 1.0/1.1 applicatio ns. The UM4258Q 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 UM4258Q logic inputs accept up to +5.5V regard less 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 in puts 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 UM4258Q changes very l ittle for analog input si gnals 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.
