Key Specifications
Product 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.
