NS5A4684S D

NS5A4684S
Ultra-Low Resistance
Dual SPDT Analog Switch
The NS5A4684S is an advanced CMOS analog switch fabricated in
Sub−micron silicon gate CMOS technology. The device is a dual
Independent Single Pole Double Throw (SPDT) switch featuring
Ultra−Low RON of 0.6 .
The part also features guaranteed Break Before Make (BBM)
switching, assuring the switches never short the driver.
