Product Description
Pericom Semiconductor’s PI3B series of logic circuits are produced
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 5channel 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-Supply Sequencing and OvervoltageProtection
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.

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, TA= 25°C 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 and B pins at indicated current through the switch. ON resistance is determined by the lower
of the voltages on the two (A & B) pins.
5. This parameter is determined by device characterization but is not production tested.
