The PI3C16210 is configured as a 20-bit, 2-port bus switch designed with a low ON resistance (5 Ohm) allowing inputs to be connected directly to outputs. The bus switch creates no additional propagational delay or additional ground bounce noise. The switch is turned ON by the Bus Enable (xOE) input signal. Logic Block Diagram stupnIs tuptuO/stupnI

This is a stress rating only and functional operation of the device at these or any other condi- tions above those indicated in the operational sec- tions of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 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 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. This parameter is determined by device characterization but is not production tested. Maximum Ratings (Above which the useful life may be impaired. For user guidelines, not tested.)

For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device. 2. Typical values are at V CC = 3.3V, +25°C ambient. 3. Per TTL driven input (control inputs only); A and B pins do not contribute to ICC. Power Supply Characteristics 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 wit h the load on the driven side.
