The PI3B32160 is a 16-bit to 32-bit demultiplexer bus switch. Industry leading advantages include a propagation delay of 250ps, resulting from 5Ω channel resistance and low I/O capacitance. A port demultiplexes to either 1B and 2B or to both. The switch is bidirectional. Application Provides PCI Hot Plugging Logic Inputs The logic cotrol inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a +3.3V supply. IN may be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail minimizes power consumption. 1B1 Logic Block Diagram VBIAS1 1A VBIAS2 1B2 Power-Supply Sequencing and Overvoltage Protection Caution: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the device. Proper power-supply sequencing is remended for all CMOS devices. Always apply VCC before applying VBIAS and signals to the input/output pins.
