PI5C16210 20-Bit, 2-Port Bus Switch Features Description ÎÎNear-Zero propagation delay The PI5C16210 is configured as 20-bit, 2-port bus switches 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 switches are turned ON by the Bus Enable (xOE) input signal. ÎÎ5-ohm switches connect inputs to outputs ÎÎDirect bus connection when switches are ON ÎÎ32X384 function with flow through pinout make board layout easier ÎÎUltra-low quiescent power (0.5μW typical) àà Ideally suited for notebook applications Pin Configuration ÎÎIndustrial operating temperature: –40°C to +85°C ÎÎPackaging (Pb-free & Green): NC 1A1 1A2 1A3 1A4 1A5 1A6 GND 1A7 1A8 1A9 1A10 2A1 2A2 VCC 2A3 GND 2A4 2A5 2A6 2A7 2A8 2A9 2A10 àà 48-pin 240-mil wide plastic TSSOP (A) Block Diagram 1A1 1B1 1A10 1B10 1EN 2A1 2B1 2A10 2B10 2EN Truth Table(1) Inputs 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 22 23 24 27 26 25 1OE 2OE 1B1 1B2 1B3 1B4 1B5 GND 1B6 1B7 1B8 1B9 1B10 2B1 2B2 2B3 GND 2B4 2B5 2B6 2B7 2B8 2B9 2B10 Pin Description Inputs/Outputs Pin Name Description Bus Enable Input (Active LOW) 1OE 2OE 1A,1B 2A,2B 1OE, 2OE L L 1A = 1B 2A = 2B 1A1-1A10, 2A1-2A10 L H 1A = 1B Z H L Z 2A = 2B H H Z Z Bus A 1B1 - 1B10, 2B1 - 2B10 Bus B Note: 1.

Typical values are at VCC = 5.0V, 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.

This parameter is guaranteed but not tested on Propagation Delays. 2. 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.
