MAX4551CEE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4551CEE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch featuring ±15kV ESD protection per IEC 1000-4-2. It operates on dual supplies from ±2V to ±6V or a single supply between +2V and +12V. The device contains four normally closed switches with an on-resistance of 120Ω max at ±5V supplies. On-resistance flatness is 8Ω max, and channel matching is 4Ω max. Off-leakage current is 1nA at +25°C and 10nA at +85°C. Logic 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 and functions within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CEE+' against the manufacturer's ordering guide to confirm the 16-pin QSOP package and commercial temperature range. Ensure the source documentation explicitly lists this part number variant as available. Cross-reference the RoHS status and lead-free compliance details provided in the official datasheet before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4551 variant specifically when normally closed switch states are required at logic zero inputs. Compare on-resistance values and leakage currents against system requirements for different supply voltages. Verify that the 16-pin QSOP footprint matches the target PCB layout constraints. Confirm that the commercial temperature range meets the operational environment standards.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX455x family of low-voltage analog switches manufactured by Analog Devices / Maxim Integrated. The family includes the MAX4551 (NC), MAX4552 (NO), and MAX4553 (mixed) variants. These devices share similar electrical characteristics and pinouts but differ in their default switch states. The MAX4551 specifically provides four normally closed channels.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet confirms pin compatibility with industry-standard DG211, DG212, and DG213 devices. Designers replacing these legacy parts should verify that the ESD protection mechanisms and holding current requirements of the internal SCRs are acceptable for the application.
