Product Description

Diodes' PI3C series of logic circuits are produced using the company's advance submicron CMOS technology, achieving industry leading performance. The PI3C3861-A is a 10-bit, 2.5volt or 3.3 volt, 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 (BE) input signal. This device is very userful in switching signals that have high bandwidth (>400 MHz).
