Overview
The NLAS4684MR2, produced by onsemi, is an advanced CMOS analog switch designed for high-performance applications. This device features a dual Independent Single Pole Double Throw (SPDT) configuration, offering ultra-low on-resistance (RON) of 0.5 Ω for the Normally Closed (NC) switch and 0.8 Ω for the Normally Opened (NO) switch at 2.7 V. Fabricated in sub-micron silicon gate CMOS technology, it ensures reliable and efficient signal switching.
