Analog Devices Inc./Maxim Integrated MAX4553CEE+

Overview

MAX4553CEE+ from Maxim Integrated is a quad, low-voltage, SPST analog switch IC with two normally closed (NC) and two normally open (NO) channels, ±15kV IEC 1000-4-2 ESD protection on NC/NO pins, 120Ω max on-resistance at ±5V supplies, rail-to-rail analog signal handling (±5V or 0–5V), and break-before-make timing (5–20ns) for glitch-free switching in precision signal routing applications.

For engineers reviewing the MAX4553CEE+ datasheet, MAX4553CEE+ pinout, MAX4553CEE+ application, or MAX4553CEE+ equivalent, this device is selected for low-leakage, high-ESD robustness analog multiplexing in battery-powered test equipment, avionics I/O conditioning, audio channel switching, and data acquisition front-ends where dual-supply flexibility and TTL/CMOS logic compatibility are required.

Technical Context

The MAX4553CEE+ integrates four independent CMOS SPST switches using complementary N- and P-channel MOSFETs per channel, driven by logic-level translators that convert TTL/CMOS inputs (0.8V/2.4V thresholds) into full-rail gate drive signals referenced to V+ and V−. Its internal SCR-based ESD protection activates within nanoseconds during ±15kV contact discharge events on NC/NO pins, shunting surge current to GND while limiting supply injection via series resistors.

It supports single-supply operation from +2.7V to +12V (V− = GND) or dual supplies from ±2V to ±6V (|V+ − V−| ≤ 13.0V), with analog signal range spanning V− to V+, on-resistance flatness of 8Ω max over that range, and channel-to-channel on-resistance match of 4Ω max - enabling matched gain/attenuation in multi-path signal conditioning circuits.

Key Specifications

Pinout & Package

MAX4553CEE+ is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.635mm pitch, 5.0mm × 4.0mm body, and exposed pad not connected internally. Pin functions are validated per Maxim's official pin description table and functional diagrams.

FAQ

What is the maximum allowable supply voltage difference for MAX4553CEE+?

The absolute maximum V+ to V− differential voltage for MAX4553CEE+ is 13.0V. This means ±6V supplies (12V total) are acceptable only if tolerance and transient overshoot remain below 13.0V - e.g., ±5% ±6V supplies (12.6V) are borderline and require careful decoupling. Exceeding 13.0V risks permanent damage. Always verify worst-case rail separation under all operating conditions before finalizing the MAX4553CEE+ power design.

Does MAX4553CEE+ support true single-supply operation down to +2.7V?

Yes, MAX4553CEE+ is fully specified for single +2.7V operation (V− = GND). At this voltage, on-resistance rises to 500Ω max, logic thresholds shift to VIN_L = 0.5V / VIN_H = 1.1V, and turn-on time increases to 400ns - all guaranteed over temperature. This enables integration into ultra-low-power IoT sensor nodes and energy-harvesting systems where the MAX4553CEE+ maintains rail-to-rail analog range (0–2.7V) and 1nA leakage.

How does the break-before-make timing work in MAX4553CEE+?

MAX4553CEE+ implements hardware-enforced break-before-make timing exclusively between its paired NC/NO channels (e.g., IN2 controls NC2, IN3 controls NC3; IN1/IN4 control NO1/NO4). When toggling between complementary states, the internal logic guarantees a 5–20ns isolation window where both paths are open - verified in Figure 2 of the datasheet. This prevents momentary shorts in applications like relay replacement or redundant signal selection where the MAX4553CEE+ replaces mechanical contacts.

Can MAX4553CEE+ be used with +3.3V logic while operating on ±5V analog supplies?

Yes. MAX4553CEE+ accepts +3.3V logic levels on IN1–IN4 because its input thresholds (VIN_L = 0.8V, VIN_H = 2.4V) are TTL/CMOS compatible at any V+ from +2.7V to +12V. With ±5V analog supplies, the internal level translators generate appropriate gate voltages for the analog switches - so the MAX4553CEE+ reliably drives its 120Ω RON channels while interfacing to modern 3.3V microcontrollers without level shifters.

What is the purpose of the N.C. pin (Pin 12) on MAX4553CEE+?

Pin 12 on MAX4553CEE+ is a no-connect terminal - it has no internal bond wire or circuit connection. It exists for mechanical symmetry and package standardization across the MAX4551/MAX4552/MAX4553 family. The MAX4553CEE+ datasheet explicitly states "N.C. = NOT CONNECTED", and Maxim recommends leaving it unconnected or tying it to GND solely for PCB mechanical stability - no electrical function or performance impact results from either choice.
