Product Description

Pericom Semiconductors PI5C series of logic circuits are produced

using the Companys advanced submicron CMOS technology.

The PI5C34X2245 is a 32-bit, 2-port bus switch. Four enable signals

(BEn) turn the switches on. The bus switch creates no

additional propagational delay or additional ground bounce noise.

The device has a built-in 25-ohm resistor to reduce noise resulting

from reflection, thus eliminating the need for an external

terminating resistor.

Notes:

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at V

= 5.0V, T

= 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 pin 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.

Notes:

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.

2. Typical values are at Vcc = 5.0V, +25°C ambient.

3. Per TTL driven input (V

= 3.4V, control inputs only); A and B pins do not contribute to Icc.

4. This current applies to the control inputs only and represent the current required to switch internal capacitance at the

specified frequency. The A and B inputs generate no significant AC or DC currents as they transition. This parameter

is not tested, but is guaranteed by design.

Notes:

1. See test circuit and waveforms.

2. This parameter is guaranteed but not tested on Propagation Delays.

3. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load

capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much

smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational

delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its

interaction with the load on the driven side.
