IDTAS4684 Datasheet | IDT

Description The IDTAS4684 low on-resistance (RON), low voltage, dual single-pole/double-throw (SPDT) analog switch operates from a single +1.8 V to +5.5 V supply. The IDTAS4684 Features a 0.5Ω (max) RON for its NC switch and a 0.8Ω (max) RON for its NO switch at a +2.7 V supply. It also Features break-before-make switching action (2 ns) with t ON = 50 ns and t OFF = 40 ns at +3 V. The digital logic inputs are 1.8 V logic-patible with a +2.7 V to +3.3 V supply. es in 3 x 3 DFN, or 12-bump CSP packages.
