Overview
The ADV3219ACPZ from Analog Devices Inc. is a high-speed, high-slew-rate, buffered, 2:1 analog multiplexer. This device is designed to handle high-speed signal switching with a -3dB signal bandwidth greater than 840 MHz and channel switch times of less than 20 ns with 1% settling. It features low crosstalk and high isolation, making it suitable for various high-speed applications. The multiplexer includes an output buffer that can be placed into a high impedance state, allowing multiple outputs to be connected together without loading the output bus.
