Voltage Operation : 1. 8 V to 5. 5 V
On-Resistance: 4.5Ω (typ) at 5.0V
High Bandwidth: 300 MHz
Fast Switching Time
The SGM4717 is a dual, bidirectional, single-pole/double-
throw (SPDT) CMOS analog switches designed to operate
from
a
single +1.8V to +5.5V supply. It features
high-bandwidth (300MHz) and low ON-resistance (4.5Ω
tON 26 ns
typ), Targeted applications for audio switching.
tOFF 20 ns

High Off-Isolation: 57dB at 10MHz
Low Crosstalk: 99dB at 10MHz
Rail-to-Rail Operation
TTL/CMOS Compatible
Break-Before-Make Switching
Extended Industrial Temperature Range:
–40°C to 85°C
SGM4717 features guaranteed on-resistance matching (0.3Ω
max) between switches and guaranteed on-resistance
flatness over the signal range (2.3Ω TYP). This ensures
excellent linearity and low distortion when switching audio
signals.
The SGM4717 is a committed dual single-pole/double
-throw (SPDT) that consist of two normally open (NO) and
two normally close (NC) switches. This configuration can
be used as a dual 2-to-1 multiplexer.
