Maxim provides a layout and routing guide in their application note AN1916, which recommends keeping the input and output traces short and away from each other, using a solid ground plane, and minimizing the use of vias.
The MAX333CWP+T requires a 3.3V or 5V power supply, and it's recommended to use a 0.1uF decoupling capacitor between the VCC pin and GND pin, as close to the device as possible. Additionally, a 10uF bulk capacitor can be used in parallel to further reduce noise.
The MAX333CWP+T is a high-speed analog switch, and it can support data rates up to 100Mbps. However, the actual data rate may be limited by the system's signal integrity and the quality of the transmission lines.
The enable pin (EN) is an active-low input that enables or disables the switch. When EN is low, the switch is enabled, and when EN is high, the switch is disabled. It's recommended to use a pull-up resistor to ensure the EN pin is properly biased when not driven.
The maximum voltage that can be applied to the input pins of the MAX333CWP+T is 5.5V, which is the absolute maximum rating. However, the recommended operating voltage range is 0V to VCC (3.3V or 5V).
