Analog Devices Inc./Maxim Integrated MAX352CSE+T

Overview

MAX352CSE+T from Maxim Integrated is a precision quad single-pole single-throw (SPST) analog switch with four normally open (NO) channels, fabricated using a 44V silicon-gate process. It delivers <35Ω on-resistance (max), <2Ω channel-to-channel matching, <10pC charge injection, and supports ±4.5V to ±20V bipolar or +10V to +30V single-supply operation - enabling rail-to-rail signal handling in military radio front-ends and precision test equipment.

For engineers reviewing the MAX352CSE+T datasheet, MAX352CSE+T pinout, MAX352CSE+T application, or MAX352CSE+T equivalent, key selection criteria include guaranteed on-resistance flatness (∆3Ω max), sub-6nA off-leakage at +85°C, ESD >2000V, TTL/CMOS logic compatibility, and narrow SO-16 packaging for space-constrained analog routing.

Technical Context

The MAX352CSE+T implements monolithic CMOS SPST switches with substrate tied to V+, enabling full rail-to-rail analog signal swing up to ±20V. Its logic inputs accept standard TTL/CMOS levels, and VL pin allows flexible interface voltage selection (5V or V+).

Switching performance is specified under dual-supply conditions (±15V): turn-on time <175ns, turn-off time <145ns, with break-before-make timing only applicable to MAX353 - not present in MAX352CSE+T. On-resistance flatness and matching are guaranteed only with bipolar supplies.

FAQ

What is the maximum analog signal voltage range supported by the MAX352CSE+T?

The MAX352CSE+T supports rail-to-rail analog signal handling from V− to V+, with absolute maximum ratings of V+ ≤ 44V referenced to V−. Under ±15V dual-supply operation, it reliably passes signals from −15.5V to +15.5V. For single-supply use (e.g., V+ = 12V, V− = 0V), the analog range spans 0V to 12V. This capability is essential for maintaining signal integrity in military radio receivers and high-dynamic-range test instrumentation where full supply utilization is required. The MAX352CSE+T achieves this via its 44V silicon-gate process and substrate-connected V+ architecture.

Does the MAX352CSE+T require external pull-up resistors on its logic inputs?

No, the MAX352CSE+T does not require external pull-up resistors on its IN1–IN4 pins. Its CMOS-compatible inputs exhibit low input current (<0.5µA) and are fully compatible with TTL and CMOS logic families when VL is set to 5V or V+. The device features internal input structure that eliminates need for external biasing - simplifying PCB layout and reducing BOM count in compact military and avionics designs. This behavior is confirmed in the Electrical Characteristics table under "Input Current with Input Voltage High/Low" (I_INH/I_INL), where values remain within ±0.5µA across temperature. The MAX352CSE+T thus operates reliably with direct FPGA or microcontroller GPIO connections.

Can the MAX352CSE+T operate with unbalanced supplies such as +24V and −5V?

Yes, the MAX352CSE+T can operate with unbalanced supplies like +24V and −5V, provided the difference between V+ and V− does not exceed +44V and each supply remains within its absolute maximum rating (V+ ≤ 44V relative to V−, GND ≤ 25V relative to V−). The datasheet explicitly states support for "unbalanced supplies such as +24V and −5V", and recommends connecting V− to 0V for single-supply use. This flexibility enables use in legacy industrial systems with asymmetric rails and hybrid power architectures. The MAX352CSE+T maintains specified R_ON, leakage, and switching times under such conditions - as verified in the "Operation with Supplies Other than ±15V" section.

What is the thermal performance of the MAX352CSE+T in narrow SOIC packaging?

The MAX352CSE+T in narrow SOIC (SO-16N) has a power dissipation derating factor of 8.70mW/°C above +70°C, with a maximum continuous power dissipation of 696mW at TA = +70°C. Its thermal resistance θ_JA is approximately 115°C/W, meaning a 100mW internal power dissipation raises junction temperature by ~11.5°C above ambient. This thermal profile supports reliable operation in convection-cooled military enclosures and industrial control cabinets. The narrow SOIC package also provides better thermal coupling to PCB copper than plastic DIP variants. All thermal specifications for the MAX352CSE+T are validated per JEDEC JESD51 standards and documented in the Absolute Maximum Ratings table.

How does the MAX352CSE+T differ from the MAX351CSE+T and MAX353CSE+T in functionality?

The MAX352CSE+T contains four normally open (NO) SPST switches, whereas the MAX351CSE+T offers four normally closed (NC) switches, and the MAX353CSE+T integrates two NO and two NC channels. Pinouts differ accordingly: MAX352CSE+T routes NO terminals to Pins 1, 12, 10, 9, while MAX351 uses NC terminals at those locations. Functionally, only MAX353 supports break-before-make timing (t_D = 25ns), which MAX352CSE+T lacks. All three share identical electrical specs (R_ON, leakage, charge injection), supply ranges, and package options - enabling drop-in replacement where switch logic state aligns with system requirements. The MAX352CSE+T is selected when default-open signal paths are needed for safety-critical isolation.
