This datasheet is about PI5C3390 and PI5C32390, These two products are 16-to-8 multiplexer/demultiplexer bus switches with a low On-Resistance, allowing inputs to be connected directly to outputs. The two enable inputs connect each of eight I/O to the common I/O pin. This multiplexer function can be used to select and route logic signals to form crossbar switches, isolate bus capacitance, or provide a zero delay switch connection. The bus switch has ultra-low quiescent power, which is ideal for notebook applications.
This document describes the Pericom Semiconductor PISC3390 and PISC32390, which are 16-to-8 multiplexer/demultiplexer bus switches. These devices allow inputs to be connected directly to outputs with a low On-Resistance, enabling direct bus connections when switches are ON.
| On-Resistance (PI5C32390) | 20 - 48 ohm |
|---|---|
| Quiescent Power | 0.2 uA typical |
| Package Type | 28-pin QSOP (Q) |
The PI5C32390 includes an internal 25-ohm resistor to reduce noise reflection in high-speed applications, whereas the PI5C3390 does not.
The device operates from -40°C to +85°C when power is applied and can be stored between -65°C and +150°C.
