PI5C3861
10-Bit, 2-Port Bus Switch
Features: Description:
Near-Zero propagation delay
Pericom Semiconductors PI5C3861 is a 10-bit, 2-port bus switch
designed with a low On-Resistance (5) allowing inputs to be
5 switches connect inputs to outputs
connected directly to outputs. The bus switch creates no additional
Direct bus connection when switches are ON
propagation delay or additional ground bounce noise. The switches
Ultra Low Quiescent Power (0.2A typical)
are turned ON by the Bus Enable (BE) input signal.
Ideally suited for notebook applications

Notes:
1. For conditions shown as Max. or Min., use appropriate value speci ed under Electrical Char ac ter is tics for the applicable device type.
2. Typical values are at V = 5.0V, TA = 25C ambient and maximum loading.
CC
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-Re sis tance is determined by the lower of the
voltages on the two (A,B) pins.
