The PI5C34X461 is a 40-bit, 2-port bus switch designed with a low ON resistance (5ohm) 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 (BE) input signal. 5ohm switches connect inputs to outputs Direct bus connection when switches are ON Ultra Low Quiescent Power (0.2 µA Typical) Ideally suited for notebook applications Packages available: 96-pin Low Profile Fine Pitch Ball Grid Array (NB96) Product Pin Description Logic Block Diagram Pin Name 1A0 1B0 2A0 2B0 1A9 1B9 2A9 2B9 1BE 2BE 3A0 3B0 4A0 4B0 3A9 3B9 4A9 4B9 3BE De s cription NA0 - NA9 Bus A NB0 - NB9 Bus B NBE Bus Enable Pins (Active LOW) NGN D Ground NVCC Power Note: N = 1 through 4 for each set of 10 bit buses 4BE Truth Table(1) Function Disconnect Connect Note: NBE H L A09 Hi-Z B09 1.

Per TTL driven input (VIN = 3.4V, control inputs only); A and B pins do not contribute to Icc. 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. 1 2 3 4 5 6 Switching Characteristics over Operating Range Parameters Description Conditions(1) PI5C34X461 Com. Min.

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 with the load on the driven side. 9 10 11 12 13 Ordering Information 14 Part Pin - Package D ime ns ions PI5C34X461NB 96 - LFBGA (NB96) 5.5mm x 13.5mm PI5C34X2461NB 96 - LFBGA (NB96) 5.5mm x 13.5mm 15 Pericom Semiconductor Corporation 2380 Bering Drive San Jose, CA 95131 1-800-435-2336 Fax (408) 435-1100 http://www.pericom.com 5 PS8408A 01/25/00
