ProductDescription
PericomSemiconductor’sPI3Bseriesoflogiccircuitsareproduced
using the Company’s advanced submicron CMOS technology,
achieving industry leading performance.
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.
Power-SupplySequencingandOvervoltageProtection
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 recommended for all CMOS
devices. Always apply VCC before applying VBIAS and signals to
the input/output pins.
