This document introduces the features of STMUX1800E, including low RON, VCC operating range, ESD protection, low power mode, channel capacitance, switching time speed, propagation delay, crosstalk, bit-to-bit skew, bandwidth, package, application scenarios, etc.
The STMUX1800E is a 16-bit to 8-bit multiplexer/demultiplexer designed for 10/100/1000 Ethernet switching applications. It features low on-resistance (4.0 Ω typical), enhanced ESD protection (>8 kV contact, >15 kV HBM), and low power consumption modes. The device integrates three SPDT switches for LED support and offers rail-to-rail switching on data I/O ports.
