BEB,AEB) WOLevitcA(tupnIelbanEsuB 9A-0AA suB 9A-0BB suB DNGd nuorG V CC rewoP BEB BEA Product Description Pericom Semiconductors PI3VT series of logic circuits are produced using the Companys advanced submicron CMOS technology, achieving industry leading performance. The PI3VT3384, is a 2.5V or 3.3V 8-bit, 2-port bus switch, is designed with a low ON resistance (5 ohms). The switches are turned ON or enabled by the Bus Enable (BEn) input signal. Given a 3.3V supply and an input voltage of 3.3V, the switch translates to an output voltage of 2.5V. Similarly, when operated with a 2.5V supply and given 2.5V inputs, the device translates the outputs to 1.8V.

Typical values are at V CC = 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 pin at indicated current through the switch. ON resistance is determined by the lower of the voltages on the two (A,B) pins. 5.

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 wit h the load on the driven side.
