PI3L500-A
3.3V, 8-Channel, 2:1 Mux/DeMux
Gigabit Ethernet LAN Switch with Single Enable
and Enhanced ESD Protection
Description
The PI3L500-Ais a 8-Channel 2:1 multiplexer/demultiplexer LAN
Switch with Hi-Z outputs. Industry leading advantages include a
propagation delay of less than 250ps, resulting from its low channel
resistance and I/O capacitance. The device multiplexes differential
outputs from a Gigabit Ethernet transceiver (PHY) device to one
of two corresponding B1 or B2 outputs. The switch is bidirectional
and offers little or no attenuation of the high-speed signals at the
outputs. It is designed for low bit-to-bit skew, high channel-to-
channel noise isolation and is compatible with various standards,
such as 10/100/1000 Base-T (Ethernet).
Generally, this part can be used to replace mechanical relays in
low-voltage LAN applications that interface a physical layer over
CAT 5 or CAT 6 unshielded twisted pair cable through an isolation
transformer.

Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between A and B pins at indicated current through the switch. ON resistance is determined by the lower of the
voltages on the two (A & B) pins.
4. This parameter is determined by device characterization but is not production tested.
