.V/.V, High Bandwidth, Hot Insertion,-Bit, -Port Bus Switch with Individual Enables Features Near-Zero propagation delay -ohm switches connect inputs to outputs High Bandwidth (>00 MHz) Rail-to-Rail, or.v or.v Switching V I/O Tolerant.V Supply Voltage Operation Permits Hot Insertion Packaging (Pb-free & Green available): -pin 0-mil wide plastic SOIC (W) -pin 0-mil wide plastic TSSOP (L) -pin 0-mil wide plastic QSOP (Q) Description Diodes PIC and PIC are. volt or. volt, -bit bus switches designed with four individual -ohm bus switches with fast indiviual enables in an industry standard XX/ pinout. When enabled via the associated Bus Enable pin, the A pin is directly connected to the B pin for that particular gate. The bus switch introduces no additional propagation delay or additional ground bounce noise. The PIC device has active LOW enables, and the PIC has active HIGH enables. It is very useful in switching signals that have high bandwidth (>00 MHz). Applications High Bandwidth Data Switching Hot Docking PIC Block Diagram PIC Block Diagram

Not more than one output should be shorted at one time. Duration of the test should not exceed one second.. 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. Capacitance (TA = C, f = MHz) Parameters () Description Test Conditions Typ. Units C IN Input Capacitance VIN = 0V.

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.ns for 0pF 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.
