PI3L500-A 3.3V, 8-Channel, 2:1 Mux/DeMux Gigabit Ethernet LAN Switch with Single Enable and Enhanced ESD Protection Features Description R is 4 typical The PI3L500-A is a 8-Channel 2:1 multiplexer/demultiplexer LAN ON Switch with Hi-Z outputs. Industry leading advantages include a Low bit-to-bit skew: 200ps propagation delay of less than 250ps, resulting from its low channel Low Crosstalk: 35dB 250MHz resistance and I/O capacitance. The device multiplexes differential Near-Zero propagation delay: 250ps outputs from a Gigabit Ethernet transceiver (PHY) device to one Switching speed: 9ns of two corresponding B1 or B2 outputs. The switch is bidirectional Channel On capacitance: 10pF (typical) and offers little or no attenuation of the high-speed signals at the Status Indicator LEDs Switched with Ethernet pairs outputs. It is designed for low bit-to-bit skew, high channel-to- V Operating Range: +3.0V to +3.6V CC channel noise isolation and is compatible with various standards, Enhanced ESD Protection: such as 10/100/1000 Base-T (Ethernet). (1) 8kV (contact) Generally, this part can be used to replace mechanical relays in Switch pins: 1.1kV (machine model), low-voltage LAN applications that interface a physical layer over 12kV (human body model) CAT 5 or CAT 6 unshielded twisted pair cable through an isolation >550 MHz bandwidth (or data frequency) transformer. Packaging: Pb-free and Green, 56-contact TQFN (ZF) Note: 1.
