PI5C3400 4-BIT, 4-PORT EXCHANGE SWITCH
PI5C3400
4-Bit, 4-Port Exchange Switch
Product Features:
Zero propagation delay Zero ground bounce flow-through mode switches connect inputs outputs Direct connection when switches Ultra Quiescent Power (0.2 Typical) Ideally suited notebook applications Packages available: 24-pin wide plastic PDIP 24-pin wide plastic QSOP 24-pin wide plastic SOIC
Product Description:
Pericom Semiconductor's PI5C series logic circuits produced Company's advanced micron CMOS technology, achieving industry leading speed grades. PI5C3400 4-bit, 4-port switch with individual exchanges designed with resistance allowing inputs connected directly outputs. switch creates additional propagational delay ground bounce noise. switches turned Enable (BE) input signal, Exchange (BX0-BX3) input signals offer individual swapping signal pairs. This exchange configuration allows swapping buses systems.

Notes: Max. Min. conditions, appropriate value specified under Electrical Characteristics applicable device. Typical values 5.0V, +25°C ambient. driven input (VIN 3.4V, control inputs only); pins contribute Icc. This current applies control inputs only represent current required switch internal capacitance specified frequency. inputs generate significant currents they transition. This parameter tested, guaranteed design.
Notes: test circuit waveforms. This parameter guaranteed tested Propagation Delays. switch contributes propagational delay other than delay resistance switch load capacitance. time constant switch alone order 0.25 load. Since this time constant much smaller than rise/fall times typical driving signals, adds very little propagational delay system. Propagational delay switch when used system determined driving circuit driving side switch interaction with load driven side.
