MAX4551CEE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4551CEE+T is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features ±15kV ESD protection per IEC 1000-4-2 and operates with dual supplies from ±2V to ±6V or a single supply between +2V and +12V. The device includes four separately controlled switches with an on-resistance of 120Ω max at ±5V supplies, matching within 4Ω max, and flatness of 8Ω max over the signal range. Off-leakage current is 1nA at +25°C and 10nA at +85°C. Digital inputs are TTL/CMOS-compatible with thresholds of +0.8V and +2.4V. Power consumption is less than 1µW. The component is housed in a 16-pin QSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the CEE suffix indicates the commercial temperature range (0°C to +70°C) and QSOP packaging. Confirm the T suffix denotes tape-and-reel delivery format. Ensure the datasheet revision matches the specific manufacturing lot requirements for your design integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when low power consumption and high ESD robustness are required for low-voltage applications. Verify that the 120Ω on-resistance meets your signal path requirements. Ensure the operating voltage stays within the specified single or dual supply limits to maintain performance specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4551/MAX4552/MAX4553 family of quad SPST analog switches. The MAX4551 variant specifically provides four normally closed switches. Other family members include the MAX4552 (four normally open) and MAX4553 (two NC, two NO). All share similar electrical characteristics and pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin compatibility with DG211/DG212/DG213. Verify electrical parameters such as on-resistance and leakage currents against these alternatives before substitution.
