Analog Devices Inc./Maxim Integrated MAX4553CEE

Overview

MAX4553CEE from Maxim Integrated is a quad, low-voltage, SPST analog switch 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, and break-before-make timing for safe signal routing in mixed-signal test equipment.

For engineers reviewing the MAX4553CEE datasheet, MAX4553CEE pinout, MAX4553CEE application, or MAX4553CEE equivalent, this device supports critical signal-path integrity in battery-powered data acquisition systems, avionics interface modules, and audio routing circuits where ESD robustness, low leakage (<1nA @ +25°C), and dual-supply flexibility (±2V to ±6V or +2V to +12V) are mandatory selection criteria.

Technical Context

The MAX4553CEE integrates four independent CMOS SPST switches with bidirectional SCR-based ESD protection on NC/NO pins-enabling ±15kV contact discharge immunity without latchup. Its logic-level translators accept TTL/CMOS inputs (VIN_H = 2.4V, VIN_L = 0.8V @ +5V supply) and drive internal N/P-channel MOSFET pairs with complementary gate signals referenced to V+ and V−.

Each channel features matched on-resistance (∆RON ≤ 4Ω), flat on-resistance (RFLAT(ON) ≤ 8Ω over signal range), and rail-to-rail analog operation bounded only by V+ and V−. The MAX4553CEE-specific break-before-make delay (tBBM = 5–20ns @ ±5V) prevents momentary shorting during channel switching in dual-configuration signal paths.

Key Specifications

Pinout & Package

MAX4553CEE is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch), RoHS-compliant, with exposed pad not connected. Pin 12 is no-connect (N.C.).

FAQ

What is the maximum supply voltage range supported by the MAX4553CEE?

The MAX4553CEE operates with dual supplies from ±2V to ±6V or a single supply from +2V to +12V. Absolute maximum ratings specify V+ to V− differential must not exceed 13.0V-so ±5V supplies with ±10% tolerance (up to ±5.5V) remain within safe limits, while ±6V supplies require tight regulation to avoid overstress. The MAX4553CEE maintains full functionality down to +2.7V single supply, making it ideal for Li-ion battery-powered devices.

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

The MAX4553CEE implements break-before-make timing exclusively between its paired NC and NO switches (e.g., NC2/NO2 and NC3/NO3). When an input transitions from logic low to high, the NC path opens first, followed by the NO path closing after a guaranteed 5–20ns delay (at ±5V). This prevents momentary shorting in applications like relay replacement or signal source selection. The MAX4553CEE's tBBM is not applicable to IN1/IN4-controlled NO1/NO4 or IN2/IN3-controlled NC2/NC3 independently-they operate as discrete SPST switches.

Can the MAX4553CEE be used with a single +3.3V supply?

Yes, the MAX4553CEE is fully specified for single +2.7V to +3.6V operation. At +3.3V, typical on-resistance is 500Ω (max), turn-on time is 190–350ns, and logic thresholds shift to VIN_H = 2.0V / VIN_L = 0.5V-remaining compatible with standard 3.3V CMOS outputs. The device retains ±15kV ESD protection and rail-to-rail analog range (0V to +3.3V), making it suitable for low-power data loggers and IoT sensor nodes powered directly from 3.3V LDOs.

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

Pin 12 on the MAX4553CEE is a no-connect (N.C.) terminal-physically present but not bonded to any internal circuitry. It must remain unconnected on the PCB; routing traces or vias to Pin 12 may cause parasitic coupling or mechanical stress. This pin exists for package compatibility across the MAX4551/MAX4552/MAX4553 family: MAX4551 uses Pin 12 as NC4, MAX4552 as NO4, while MAX4553 repurposes it as N.C. to accommodate its unique two-NC/two-NO configuration within the same 16-pin QSOP footprint.

Does the MAX4553CEE require external ESD protection components?

No, the MAX4553CEE does not require external ESD protection on its NC or NO pins-the device integrates bidirectional SCRs that clamp ±15kV IEC 1000-4-2 contact discharges directly to GND. However, V+ and V− pins retain standard ESD diodes to GND and should be bypassed with 100nF capacitors per the datasheet. External protection is unnecessary for NC/NO pins in compliant system-level testing, reducing BOM cost and layout complexity versus unprotected switches like the DG212.
