Description
Pericom Semiconductor’s PI5C16862C is configured as a 20-bit, 2-
port bus switch designed with a low On-Resistance (5-ohm) 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 (BEx) input
signal.
The PI5C16862C can withstand undershoot of up to –1V.
