MAX4553CEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4553CEE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two normally closed and two normally open switches within a 16-pin QSOP package. The device operates with dual supplies from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include a maximum on-resistance of 120Ω, an on-resistance flatness of 8Ω max, and channel-to-channel matching of 4Ω max. Off-leakage current is limited to 1nA at +25°C. The component provides ±15kV ESD protection per IEC 1000-4-2 and supports Rail-to-Rail analog signals.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CEE' corresponds to the commercial temperature range (0°C to +70°C) and 16-pin QSOP package configuration. Confirm RoHS compliance status as historical documentation may list non-compliant variants for older production runs. Cross-reference the manufacturer part number with official distributor catalogs to ensure availability of the exact package variant required for the design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4553CEE when a mix of normally open and normally closed switches is required within a single quad package. Ensure the application signal range remains within the specified V+ and V- limits to maintain on-resistance flatness. Verify that the system can tolerate the break-before-make timing characteristics inherent to the MAX4553 architecture during switching transitions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4551/MAX4552/MAX4553 family of low-voltage SPST analog switches. While the MAX4551 offers four normally closed switches and the MAX4552 provides four normally open switches, the MAX4553 combines two of each type. All three variants share identical pinouts and electrical characteristics except for the internal switch configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states pin compatibility with DG211, DG212, and DG213. Designers should verify that substitute components meet the specific ±15kV ESD protection requirements and on-resistance flatness specifications defined in the original design constraints.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4553 handle ESD events on the analog pins?

The device incorporates bidirectional SCRs between the NC/NO pins and GND. These SCRs turn on rapidly during an ESD strike to bypass surge current to ground, preventing latchup or damage without requiring external protection components.

What is the break-before-make behavior of the MAX4553?

As a MAX4553 device, it features mixed NO and NC switches. When switching states, there is a guaranteed break-before-make time delay to prevent short circuits between the common terminal and the opposite state terminal during transition.

Can the MAX4553 operate with asymmetric power supplies?

Yes, the V+ and V- supplies need not be symmetrical. However, the total differential voltage between V+ and V- must not exceed the absolute maximum rating of 13.0V to avoid device damage.
