STMUX1800E

16-bit to 8-bit MUX/DEMUX for gigabit Ethernet LAN switch

with LED switch and enhanced ESD protection

Features

■ Low R : 4.0 Ω typical

■ V

operating range: 3.0 to 3.6 V

■ 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

■ 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.
