MAX4888BGTI+

Analog Switches - Special Purpose Overview

The MAX4888BGTI+ is a dual double-pole/double-throw (2 x DPDT) high-speed passive switch designed for routing differential signals such as PCIe, SAS, SATA, and XAUI. It operates from a single +3.0V to +3.6V power supply with a typical current of 1 mA. The device supports data rates up to 8.0Gbps and features an on-resistance of 6.4 Ohms typical at 3.0V. Switching times are 65 ns turn-on and 7 ns turn-off. It includes propagation delay of 43 ps and output skew of 8 ps. The component is housed in a 28-pin TQFN package measuring 3.5mm x 5.5mm and operates within a temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix GTI against official documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the ordering code matches the required electrical characteristics and thermal performance specifications for your design.

Analog Switches - Special Purpose Selection Notes

Select the MAX4888B variant for direct connection applications without internal biasing. Choose the MAX4888C variant if the system requires capacitive coupling at both input and output, as it provides internal biasing resistors and source current. Ensure the PCB layout adheres to controlled impedance guidelines to maintain signal integrity at high frequencies.

Analog Switches - Special Purpose Part Context

This component belongs to the Maxim Integrated MAX4888 family of high-speed analog switches. It is specifically engineered for PCIe and storage interface switching applications. The device enables resource sharing between hosts and devices or redundancy configurations in server and PC architectures.

Analog Switches - Special Purpose Replacement Considerations

The MAX4888CETI+ serves as a functional alternative within the same series, offering identical switching capabilities but with added internal biasing resistors suitable for capacitively coupled systems.
