PI5C3861
10-Bit, 2-Port Bus Switch
Product Description:
Pioneer Semiconductor聮s PI5C series of logic circuits are pro-duced
in the Company聮s advanced submicron CMOS technology,
achieving industry leading performance.
The PI5C3861 is a 10-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.
