The PI3B16209 and PI3B162209 are 3.3 volt, 18-bit bus exchange switches designed with a low ON resistance (5W ) allowing inputs to be connected directly to outputs. The devices operate as an 18-bit bus switch or as a 9-bit exchanger, providing data exchange between the four signal ports via the data select pins (S0-S2). The PI5C162209 device has a built-in 25-ohm series resistor to reduce noise resulting from reflections, thus eliminating the need for an external terminating resistor. Product Features

For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at Vcc = 3.3V, TA = 25°C ambient and maximum loading. 3. 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. 4. 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.) Note: Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the opera- tional sections of this specification is not implied. Exposure to absolute maximum ra ting conditions for extended periods may affect reliability.

For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device. 2. Typical values are at Vcc = 3.3V, +25°C ambient. 3. Per TTL driven input (control input only); A and B pins do not contribute to I CC . 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. Switching Characteristics over Operating Range 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 0.25 ns for 50 pF 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. Com.
