UM4258Q 4.5Ω 300MHz Bandwidth Dual SPDT Analog Switch UM4258Q QFN10 1.80×1.40 General Description The UM4258Q 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 UM4258Q 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 UM4258Q is packaged in a 1.80mm ×1.40mm QFN10 package, which significantly reducing the required PC board area.

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 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 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 UM4258Q 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. ________________________________________________________________________ http://www.union-ic.com Rev.04 Dec.2014 10/14 UM4258Q ________________________________________________________________________ http://www.union-ic.com Rev.04 Dec.2014 11/14 UM4258Q ________________________________________________________________________ http://www.union-ic.com Rev.04 Dec.2014 12/14 UM4258Q Package Information UM4258Q: QFN10 1.80×1.40 Outline Drawing DIMENSIONS b D L1 PIN 1 IDENTIFICATION e E L Symbol MILLIMETERS Min Typ Max Min Typ Max A 0.50 0.55 0.60 0.020 0.022 0.024 A1 0.00 - 0.05 0.00 - 0.002 A3 BOTTOM VIEW 0.15REF 0.006REF b 0.15 0.20 0.25 0.006 0.008 0.010 D 1.35 1.40 1.45 0.054 0.056 0.058 E 1.75 1.80 1.85 0.07 0.072 0.074 A TOP VIEW INCHES A3 A1 e SIDE VIEW 0.40BSC 0.016BSC L 0.30 0.40 0.50 0.012 0.016 0.020 L1 0.40 0.50 0.60 0.016 0.020 0.024 Land Pattern 1.70 9×0.563 0.663 0.40 2.10 1 NOTES: 1.
