单4 ：1的低rON的多路复用器 Single 4:1 Low rON Multiplexers
DESCRIPTION
The DG2034 is a low voltage, low rON, high bandwidth single 4 to 1 analog multiplexer designed for high performance switching of analog and video signals. Combining low power; fast switching; low on-resistance, flatness and matching; and small physical size, the DG2034 is ideal for portable and battery applications.
Built on Vishay Siliconix’s low voltage CMOS process, the DG2034 has an epitaxial layer which prevents latchup. Break-before-make is guaranteed.
