The PI5C3384, PI5C3384C, and PI5C32384 are 10-bit, 2-port bus switches designed with a low ON resistance 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. Two bus enable signals are provided, one for each of the upper and lower five bits of the two 10-bit buses. The PI5C32384 is designed with an internal 25ohm resistor reducing noise reflection in high-speed applications.

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. 3 PS 7029B 11/18/02 PI5C3384/3384C/32384 (25 Ohm) 10-Bit, 2-Port Bus switch 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 PI5C32384 Switching Characteristics over Operating Range PI5C32384 Parameters Description t PLH t PHL tPZH tPZL tPHZ tPLZ Propagation Delay Ax to Bx, Bx to Ax Bus Enable Time BEX to Ax or Bx Bus Disable Time BEx to Ax or Bx (2,3) Conditions(1) Min Typ Max Unit CL = 50 pF RL = 500ohm — 1.25 — ns 1.5 — 7.5 ns 1.5 — 5.5 ns Notes: 1.
