Analog Devices Inc./Maxim Integrated MAX4663CPE

Overview

MAX4663CPE from Maxim Integrated is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, featuring guaranteed break-before-make switching, 2.5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling - used in precision ADC multiplexing and reed-relay replacement in test equipment.

For engineers reviewing the MAX4663CPE datasheet, MAX4663CPE pinout, MAX4663CPE application, or MAX4663CPE equivalent, key selection criteria include verified break-before-make timing (5–125 ns), channel-to-channel R_ON match ≤0.5Ω, off-leakage ≤0.5nA at +85°C, and TTL/CMOS-compatible logic inputs with separate VL supply.

Technical Context

The MAX4663CPE implements four independent CMOS transmission gates in a single 16-pin plastic DIP package, with dedicated IN1–IN4 control inputs driving two NO (switches 1 & 4) and two NC (switches 2 & 3) configurations. Its internal architecture guarantees break-before-make operation exclusively for the MAX4663 variant - not shared with MAX4661/MAX4662 - preventing momentary shorting during state transitions.

It supports dual-supply operation (±4.5V to ±20V) or single-supply (4.5V to 36V), with a separate VL pin enabling TTL/CMOS logic compatibility across the full analog supply range. On-resistance flatness is specified at ≤0.7Ω over the full signal range, and R_ON matching between channels is guaranteed ≤0.4Ω (typ) / ≤0.5Ω (max).

FAQ

What is the maximum allowable voltage difference between V+ and V− for MAX4663CPE?

The absolute maximum rating specifies V+ to V− must not exceed +44V. This limit ensures safe operation under transient conditions and defines the total analog supply headroom - for example, ±20V dual supplies (40V total) or +36V/0V single supply (36V) both comply. Exceeding 44V risks permanent damage per the datasheet's Absolute Maximum Ratings table. The MAX4663CPE must always operate within this constraint to maintain reliability and parameter guarantees.

Does MAX4663CPE support true break-before-make operation across all temperature ranges?

Yes - break-before-make timing (t_OPEN = 5–125 ns) is guaranteed over the full 0°C to +70°C operating range for MAX4663CPE, as confirmed in the Electrical Characteristics table under "Switch Dynamic Characteristics." This guarantee applies specifically to the MAX4663 variant and is not shared with MAX4661 or MAX4662. No external timing circuitry is needed to enforce this behavior.

Can MAX4663CPE be used with a 3.3V logic supply while operating from ±15V analog rails?

Yes - the dedicated VL pin allows independent logic supply connection. For MAX4663CPE, VL may be set to 3.3V while V+ = +15V and V− = −15V, maintaining full TTL/CMOS compatibility (VIN_H = 2.4V min, VIN_L = 0.8V max). This decoupling eliminates level-shifter requirements and ensures reliable IN1–IN4 control across mixed-voltage system architectures.

What is the typical off-isolation performance of MAX4663CPE at 1MHz?

At 1MHz, MAX4663CPE delivers −56dB off-isolation (typical) under dual-supply conditions (V+ = +15V, V− = −15V), as measured per Figure 5 in the datasheet. This value degrades with frequency due to capacitive coupling - dropping to −45dB at 10MHz - so high-frequency isolation-critical applications should verify performance at the target frequency using the provided test circuit.

Is the 2.5Ω on-resistance specification for MAX4663CPE valid across the full signal range and temperature?

No - the 2.5Ω maximum on-resistance is specified at TA = +25°C and VCOM = ±10V (dual supply) or VCOM = 10V (single supply). At extremes (e.g., VCOM = ±20V or TA = +70°C), R_ON increases to 4Ω max per the Single Supply Electrical Characteristics table. Designers must consult the R_ON vs. VCOM and temperature graphs (Figures 1–4) to confirm performance at actual operating points for MAX4663CPE.
