PI3B33X257 3.3V, 24:12 Mux/DeMux NanoSwitch Features Description Near-Zero propagation delay Pericom Semiconductors PI3B33X257 is a 3.3V, 24:12 multiplexer/ demultiplexer with three-state outputs. Inputs can be connected 5 switches connect inputs to outputs to outputs with low on resistance (5) with no additional ground Direct bus connection when switches are ON bounce noise or propagation delay. Ultra Low Quiescent Power (0.2A Typical) Ideally suited for notebook applications TTL - compatible control of input levels Fast switching speed - 4.5ns max.
