NLAS4684/D
NLAS4684
Ultra-Low Resistance
Dual SPDT Analog Switch
The NLAS4684 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 R
ON
of 0.5 , for the Normally Closed (NC) switch, and
0.8 for the Normally Opened switch (NO) at 2.7 V.
The part also features guaranteed Break Before Make switching,
assuring the switches never short the driver.
The NLAS4684 is available in a 2.0 x 1.5 mm bumped die array.
The pitch of the solder bumps is 0.5 mm for easy handling.
