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.

Typical values are at VCC = 5.0V, +25°C ambient. 3. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND. 4. Per TTL driven input (VIN = 2.7V, control inputs only); A and B pins do not contribute to ICC. 5. 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.

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. 3 PS7023J 09/09/04 PI5C16212 24-Bit Bus-Exchange Switch 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 56-Pin 173-Mil Wide Plastic TVSOP (K) Package 56 4.30 4.50 .169 .177 0.09 0.20 .0035 .008 1 .441 .449 0.45 .018 0.75 .030 .031 .041 0.80 1.05 11.20 11.40 .252 BSC 6.4 SEATING PLANE .016 BSC 0.40 X.XX X.XX .047 1.20 Max. .002 .006 0.05 0.15 .005 .009 0.13 0.23 DENOTES DIMENSIONS IN MILLIMETERS 56-Pin 240-Mil Wide Thin Plastic TSSOP (A) Package 56 .236 .244 1 .547 .555 6.0 6.2 13.9 14.1 1.20 .047 Max.
