ETC NLAS4685/D

NLAS4685
Ultra−Low Resistance
Dual SPDT Analog Switch
The NLAS4685 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 0.8 , for the Normally Closed (NC) switch and
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 NLAS4685 is available in a 2.0 x 1.5 mm bumped die array,
with a 3 x 4 arrangement of solder bumps. The pitch of the solder
bumps is 0.5 mm for easy handling.
