Description
The STG4158 is a high-speed CMOS low voltage
single analog SPDT (single pole dual throw)
switch or 2:1 multiplexer/ demultiplexer switch
fabricated in silicon gate C²MOS technology.
Designed to operate from 1.65 to 4.5 V, this
device is ideal for portable applications.
It offers low ON resistance (0.6 Ω) at V_CC = 4.5 V (
typical T_A = 25 ºC). The SEL input threshold is
compatible to 1.8 V, and provides control to the
switches.
Flip-Chip6
The switch S1 is ON (connected to common port
D) when the SEL input is held high and OFF (high
impedance state exists between the two ports)
when SEL is held low. The switch S2 is ON
(connected to common port D) when the SEL
input is held low and OFF (high impedance state
exists between the two ports) when SEL is held
high.
The SEL input has an integrated weak pull-down
resistor to prevent SEL signal from floating. For
low power consumption, the SEL input must be
grounded.
Power-off and over-voltage protection
The STG4158 features power-off and over-
voltage protection, enabling the device to be
isolated during voltage fault events.
