MAX4718EBC-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4718EBC-T is a dual single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and features a low on-resistance of 4.5 Ohms maximum. The device provides a -3dB bandwidth of 300 MHz, enabling high-speed signal routing. Key electrical specifications include a charge injection of 5 pC, channel-to-channel matching of 100 mOhms, and a crosstalk rejection of -110 dB at 1 MHz. Switching times are specified with a maximum turn-on time of 80 ns and a turn-off time of 40 ns. The component is housed in a compact 12-pin UCSP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the exact ordering suffix and package variant when sourcing, as availability may vary by distributor. Confirm RoHS compliance status and lead times directly with authorized suppliers. Ensure the specific batch matches design requirements for temperature range and electrical tolerances before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPDT switch with high bandwidth and low on-resistance is required. Consider the 1.8 V to 5.5 V supply range compatibility with system logic levels. Evaluate the 4.5 Ohm on-resistance against signal integrity needs. The UCSP package size should be assessed against available PCB real estate constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context
