ProductDescription
PericomSemiconductorsPI5Cseriesoflogiccircuitsareproduced
using the companys advanced submicron CMOS technology.
ThePI5C16215Cprovides20-bitsofhigh-speedbusswitching.The
low on-state resistance of the switch allows connections to be made
with minimal propagation delay. The device also precharges the
B-port to a user-selectable bias voltage (BIASV) to minimize live-
insertion noise. The device incorporates an internal charge pump
to handle input undershoot of up to 1.5V and 25ns width.
The device is organized as dual 10-bit bus switches with individual
output-enable (OE) inputs. When OE is low, the corresponding
10-bit bus switch is on and port A is connected to port B. When OE
is high, the switch is open, a high-impedance state exists between
the two ports, and port B is precharged to BIASV through the
equivalent of a 10-k ohm resistor.
To ensure the high-impedance state on power up or power down,
OE should be tied to VCC through a pullup resistor; the minimum
value of the resistor is determined by the current-sinking capability
of the driver connected to OE.
