PI5C3390, PI5C32390 (25) 16-to-8 Multiplexer/Demultiplexer Bus Switch Features: Description: Near-Zero propagation delay Pericom Semiconductors PI5C3390 and PI5C32390 are 16-to-8 Low noise, 25-ohm version (PI5C32390) multiplexer/demultiplexer bus switches with a low On-Resistance allowing inputs to be connected directly to outputs. The two enable 5-ohm switches connect inputs to outputs (PI5C3390) inputs connect each of eight I/O to the common I/O pin. This Direct bus connection when switches are ON multiplexer function can be used to select and route logic signals to Ultra-low quiescent power (0.2A typical) form crossbar switches, isolate bus capacitance, or provide a zero Ideally suited for notebook applications delay switch connection. The bus switch creates no additional Packaging (Pb-free & Green available): ground bounce noise or additional propagation delay. The PI5C32390 28-pin 150-mil wide plastic QSOP (Q) is designed with an internal 25-ohm resistor reducing noise reflection in high-speed applications.

Typical values are at Vcc= 5.0V, TA = 25C ambient and maximum loading. 3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second. 4. Measured by the voltage drop between A, B, and C pins at indicated current through the switch. On-Resistance is determined by the lower of the voltages on the two (A,B,C) pins.
