Analog Devices Inc./Maxim Integrated MAX353CSE

Overview

MAX353CSE from Maxim Integrated is a precision quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, fabricated in a 44V silicon-gate process. It delivers <35Ω on-resistance (max), <2Ω channel-to-channel match, <3Ω on-resistance flatness over rail-to-rail analog signals (±15V), <10pC charge injection, and <6nA off-leakage at +85°C - enabling high-accuracy signal routing in military radios and guidance systems.

For engineers reviewing the MAX353CSE datasheet, MAX353CSE pinout, MAX353CSE application, or MAX353CSE equivalent, key selection criteria include guaranteed on-resistance matching across temperature, bipolar/split-supply operation (±4.5V to ±20V), single-supply compatibility (+10V to +30V), CMOS/TTL logic input compatibility, and ESD robustness (>2000V per Method 3015.7).

Technical Context

The MAX353CSE implements four independent SPST switches in a monolithic CMOS architecture with substrate tied to V+, enabling rail-to-rail analog signal handling up to ±20V. Its logic interface accepts standard TTL/CMOS levels via VL pin (configurable to 5V or V+), while dual-supply operation ensures symmetric switching performance and low distortion.

Charge injection is tightly controlled (<10pC) through matched transistor design and layout symmetry, critical for sample-and-hold accuracy. Break-before-make timing (25ns max) is specified only for the MAX353 variant - ensuring safe channel isolation during switching transitions in multiplexed data acquisition paths.

FAQ

What is the maximum analog signal voltage range supported by the MAX353CSE?

The MAX353CSE supports an analog signal range of ±15.5V when operated with bipolar supplies (e.g., V+ = +16.5V, V− = −16.5V), and 0V to +12V with single-supply operation (V+ = +12V, V− = 0V). This rail-to-rail capability is enabled by its 44V breakdown voltage and substrate connection to V+, ensuring full signal swing without clipping or distortion in precision measurement paths. The MAX353CSE maintains <3Ω on-resistance flatness across this entire range.

How does the MAX353CSE differ from the MAX351CSE and MAX352CSE in switch configuration?

The MAX353CSE integrates two normally open (NO) and two normally closed (NC) SPST switches in a single 16-pin package - unlike the MAX351CSE (four NC only) and MAX352CSE (four NO only). This hybrid configuration enables simultaneous signal pass-through and default-safe routing in safety-critical systems, such as guidance control where NC paths maintain fail-safe biasing while NO paths enable active signal injection. Pin assignments for NO1/NO4 and NC2/NC3 are fixed per the MAX353CSE datasheet.

Does the MAX353CSE require external components for proper logic-level interfacing?

No, the MAX353CSE includes a dedicated VL pin that allows direct TTL (5V) or CMOS (V+) logic compatibility without external level shifters. When VL is tied to +5V, the device accepts standard TTL input thresholds (VINH = 2.4V, VINL = 0.8V); when tied to V+, it supports CMOS-compatible thresholds. This dual-mode flexibility eliminates external components and simplifies integration with FPGAs, microcontrollers, and mixed-voltage digital systems - a key advantage confirmed in the MAX353CSE functional diagrams and truth tables.

What is the guaranteed break-before-make timing specification for the MAX353CSE?

The MAX353CSE guarantees a maximum break-before-make time delay of 25ns (typical 15ns) under RL = 300Ω and CL = 35pF load conditions, as measured per Figure 3 in the official datasheet. This parameter is unique to the MAX353 variant and is not specified for MAX351CSE or MAX352CSE. It ensures safe channel isolation during switching transitions - critical in multiplexed data acquisition to prevent momentary shorts between signal sources or loads in the MAX353CSE application circuitry.

Can the MAX353CSE operate from unbalanced supply voltages such as +24V and −5V?

Yes, the MAX353CSE supports unbalanced supplies - for example, +24V and −5V - provided the absolute difference between V+ and V− does not exceed +44V (per Absolute Maximum Ratings). In such configurations, the analog signal range is constrained by the lesser of |V+| or |V−|, and VL must be referenced accordingly (e.g., to +5V for TTL logic). This flexibility is explicitly documented in the "Operation with Supplies Other than ±15V" section of the MAX353CSE datasheet and validated in Typical Operating Characteristics curves.
