SGM84782
GENERAL DESCRIPTION
The SGM84782 is high-speed, low-voltage, low
on-resistance, CMOS analog multiplexer/switch that
configured as two 4-channel multiplexers. It operates
from a single +1.8V to +4.2V power supply. Targeted
applications include battery powered equipment that
benefit from low R
ON
(4Ω) and fast switching speeds
(t
ON
= 17 ns, t
OFF
= 9 ns).
The SGM84782 can handle rail-to-rail analog signals
and is available in TQFN-16 and TSSOP-16 packages.
