Analog Devices Inc./Maxim Integrated MAX364CPE

Overview

MAX364CPE from Maxim Integrated is a precision quad SPST analog switch with normally closed (NC) configuration, designed for high-fidelity signal routing in precision instrumentation and test equipment. It delivers <85Ω on-resistance, <2Ω channel-to-channel matching, <10pC charge injection, rail-to-rail analog signal handling (±15V), and operates from ±4.5V to ±20V dual supplies or +10V to +30V single supply.

For engineers reviewing the MAX364CPE datasheet, MAX364CPE pinout, MAX364CPE application, or MAX364CPE equivalent, this device is selected for low-distortion multiplexing in sample-and-hold circuits, military radio front-ends, and battery-operated guidance systems where leakage (<4nA at +85°C), fast switching (<250ns turn-on), and ESD robustness (>2000V) are critical.

Technical Context

The MAX364CPE implements four independent CMOS-controlled SPST switches fabricated in Maxim's 44V silicon-gate process, enabling true rail-to-rail analog conduction without level-shifting. Its matched on-resistance and flat R_ON (∆9Ω max) ensure minimal gain/phase error across channels and signal range.

It features TTL/CMOS-compatible logic inputs (VL pin configurable for 5V or V+ reference), low power consumption (35µW typical), and guaranteed charge injection <10pC - critical for minimizing droop in precision sampling applications. All electrical specs are validated over 0°C to +70°C for the CPE variant.

FAQ

What is the maximum analog signal voltage range supported by the MAX364CPE?

The MAX364CPE supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of ±44V between V+ and V−. When operated on ±15V supplies, the full analog range is −15V to +15V. The device maintains specified on-resistance flatness and leakage across this entire range, enabling direct interfacing with op-amps and ADCs without external clamping or level-shifting circuitry. This capability is confirmed in the Electrical Characteristics tables for dual-supply operation.

Does the MAX364CPE require external pull-up or pull-down resistors on its logic inputs?

No, the MAX364CPE does not require external pull-up or pull-down resistors on IN1–IN4. Its CMOS inputs have high impedance and are fully compatible with TTL and CMOS logic levels when VL is set to +5V or V+. Input current is specified as ±0.5µA max over temperature, ensuring reliable switching without external biasing. This simplifies PCB layout and reduces BOM count in space-constrained applications like portable test gear.

How does the MAX364CPE behave when power supplies are removed?

When all supplies (V+, V−, VL, GND) are removed, the MAX364CPE switches enter an open state - meaning all NC paths disconnect. This is due to internal protection structures that disable conduction in unpowered conditions. The device does not pass analog signals in the absence of power, preventing unintended signal coupling or backfeeding in fault scenarios. This behavior is explicitly stated in the Applications Information section under "Switches are open when power is off."

Can the MAX364CPE operate from a single +12V supply, and what are the implications?

Yes, the MAX364CPE can operate from a single +12V supply with V− tied to GND. In this configuration, the analog signal range becomes 0V to +12V, and on-resistance increases slightly (typ. 100Ω vs. 85Ω max at ±15V). Turn-on time extends to 160ns max, and leakage remains within spec. The VL pin must be connected to +5V for TTL compatibility. This mode is validated in the Single-Supply Electrical Characteristics table and supports battery-powered instrumentation where negative rails are impractical.

What is the thermal performance of the MAX364CPE in plastic DIP packaging?

The MAX364CPE in 16-pin plastic DIP has a power dissipation limit of 842mW at +70°C ambient, derating at 10.53mW/°C above that temperature. Junction-to-ambient thermal resistance (θ_JA) is approximately 119°C/W. Under typical operating conditions (e.g., 4 channels conducting 10mA each at 85Ω), power dissipation remains well below this limit, allowing reliable operation up to +70°C without heatsinking. This data is specified in the Absolute Maximum Ratings table under "Continuous Power Dissipation."
