Analog Devices Inc./Maxim Integrated MAX313CSE-T

Overview

MAX313CSE-T from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) CMOS analog switch optimized for bidirectional signal routing in precision analog systems. It delivers 6.5Ω typical on-resistance, 1.5Ω max on-resistance matching between channels, and rail-to-rail signal handling across ±4.5V to ±20V dual supplies or +4.5V to +30V single supply - enabling low-distortion audio routing and high-fidelity data acquisition.

For engineers reviewing the MAX313CSE-T datasheet, MAX313CSE-T pinout, MAX313CSE-T application, or MAX313CSE-T equivalent, key selection criteria include guaranteed R_ON flatness (≤2Ω), >96dB crosstalk at 20kHz, <30pC charge injection, and ESD tolerance >2000V per Method 3015.7 - critical for test equipment, avionics, and PBX signal path integrity.

Technical Context

The MAX313CSE-T implements a fully complementary CMOS switch architecture with matched P- and N-channel transistor pairs per channel, ensuring symmetrical conduction and minimal THD across the full analog signal range. Its logic interface accepts TTL/CMOS-compatible inputs referenced to VL (independent logic supply), decoupling digital control from analog supply domains.

Each of the four NO switches operates independently with break-before-make timing controlled by internal gate drive sequencing; the MAX313 variant excludes break-before-make functionality (unlike MAX314), simplifying timing analysis in multiplexed sampling paths where channel overlap is acceptable.

Key Specifications

FAQ

What is the maximum analog signal voltage range supported by the MAX313CSE-T?

The MAX313CSE-T supports analog signals from V− to V+ across its full specified supply range: ±4.5V to ±20V (dual supply) or +4.5V to +30V (single supply). With V− tied to GND, the signal range extends from 0V to V+, enabling true rail-to-rail operation - critical for preserving dynamic range in audio and sensor interfaces. Absolute maximum ratings allow V+ up to +44V and V− down to −44V, but functional operation is limited to the specified supply ranges.

Does the MAX313CSE-T require external pull-up or pull-down resistors on its logic inputs?

No, the MAX313CSE-T does not require external pull-up or pull-down resistors on IN1–IN4. Its logic inputs are CMOS-compatible with guaranteed thresholds: VINH ≥ 2.4V and VINL ≤ 0.8V when VL = 5V. Input leakage is ±0.5µA max, so direct connection to microcontroller GPIOs or FPGA outputs is safe. External resistors are only needed if driving from open-drain sources or when level-shifting between incompatible logic families.

Can the MAX313CSE-T be used in a single-supply configuration with V− connected to GND?

Yes, the MAX313CSE-T is fully qualified for single-supply operation: connect V− to GND, apply V+ between +4.5V and +30V, and set VL to 3V or 5V. In this mode, the analog signal range becomes 0V to V+, maintaining rail-to-rail capability. Electrical characteristics - including 6.5Ω typical R_ON, ≤2.5nA leakage at +85°C, and <30pC charge injection - are guaranteed across the full single-supply range per the datasheet's "Single Supply" test conditions.

How does the MAX313CSE-T compare to the MAX314 in terms of switching behavior?

The MAX313CSE-T contains four independent normally open (NO) switches, while the MAX314 integrates two NO and two normally closed (NC) switches in one package. Unlike the MAX314, the MAX313CSE-T does not implement break-before-make timing - all switches transition directly between states. This makes MAX313CSE-T simpler for non-overlapping routing (e.g., channel selection), whereas MAX314 is preferred for applications requiring guaranteed isolation during state transitions, such as relay replacement in safety-critical paths.

Is the MAX313CSE-T pin-compatible with industry-standard analog switches?

Yes, the MAX313CSE-T is explicitly pin-compatible with the DG411, DG412, and DG413 series from Vishay Siliconix. Pin assignments for INx, COMx, NOx, V+, V−, GND, and VL match exactly across all devices. This allows direct substitution in existing PCB layouts without modification - provided supply voltages, signal ranges, and temperature requirements align with the MAX313CSE-T's specifications.
