SW4684 - Ultra Low Resistance Dual SPDT Analog Switch

General Description

The SW4684 is an advanced CMOS analog switch that operates from a single +1.8V to +5.5V supply.

The device is a dual independent single pole double throw (SPDT) switch featuring ultra-low RON of 0.5Ω for the normally closed (NC) switch, and 0.8Ω for the normally opened switch (NO) at 2.7 V.

Key Features

  • break-before-make switching action with tON = 50ns and tOFF = 40ns at +3V. The digital logic inputs are 1.8V logic interface compatible with a +2.7V to +3.3V supply. Key Specifications Single Supply Operation High Isolation Low Standby Current Low Crosstalk 3dB Bandwidth at VCC = 5V 1.8V to 5.5V -66dB at 100kHz.
