with LED switch and enhanced ESD protection
Features
■ Low R : 4.0 Ω typical
ON
■ V
operating range: 3.0 to 3.6 V
CC
■ Enhanced ESD protection: > 8 kV (contact)
and 15 kV (HBM)
■ Low power mode for minimum power
consumption
■ Channel on capacitance: 9.5 pF typical
■ Switching time speed: 9 ns
■ Near to zero propagation delay: 250 ps
■ Very low crosstalk: -45 dB at 250 MHz
■ Bit-to-bit skew: 200 ps
QFN42
■
> 600 MHz -3 dB typical bandwidth (or data
frequency)
Description
The STMUX1800E is a 16 to 8-bit multiplexer/
■ Three SPDT switches for LED support
demultiplexer low R bidirectional LAN switch
ON
■ Rail-to-rail switching on data I/O ports
designed for various standards, such as
10/100/1000 Ethernet. It is designed for very low
crosstalk, low bit-to-bit skew and low I/O
capacitance.
(0 V to 5 V)
■ Package: QFN42
■ Lead-free
The differential signal from the Gigabit Ethernet
transceiver is multiplexed into one of two selected
outputs while the unselected switch goes to Hi-Z
status.
Applications
■ 10/100/1000 Mbit Ethernet switching
■ Audio/video switching
The device integrates three SPDT (single pole
dual throw) switches, for LED support.
The device can be put into low power mode
consuming minimum power.
