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 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 QFN42 Very low crosstalk: -45 dB at 250 MHz Bit-to-bit skew: 200 ps > 600 MHz -3 dB typical bandwidth (or data Description frequency) 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 (0 V to 5 V) 10/100/1000 Ethernet. It is designed for very low crosstalk, low bit-to-bit skew and low I/O Package: QFN42 capacitance. Lead-free The differential signal from the Gigabit Ethernet transceiver is multiplexed into one of two selected Applications outputs while the unselected switch goes to Hi-Z 10/100/1000 Mbit Ethernet switching status. 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. Table 1.
