Analog Devices Inc./Maxim Integrated MAX364CSE+

Overview

MAX364CSE+ from Maxim Integrated is a precision quad SPST analog switch with normally closed (NC) configuration, designed for high-fidelity signal routing in rail-to-rail analog paths. It delivers <85Ω on-resistance (max), <2Ω channel-to-channel matching, <10pC charge injection, <4nA off-leakage at +85°C, and 250ns turn-on time-enabling accurate sampling in test equipment and guidance systems.

For engineers reviewing the MAX364CSE+ datasheet, MAX364CSE+ pinout, MAX364CSE+ application, or MAX364CSE+ equivalent, this page provides verified electrical parameters, SO-16 pin mapping, real-world use cases in military radios and sample-and-hold circuits, and two validated alternative parts with documented functional and application differences.

Technical Context

The MAX364CSE+ uses Maxim's 44V silicon-gate process to achieve low distortion and stable on-resistance over full analog signal range (±15V with ±15V supplies). Its CMOS/TTL-compatible control inputs drive four independent NC switches with matched R_ON and flat ∆R_ON (≤9Ω), ensuring consistent gain and minimal crosstalk (<100dB).

It operates from single-supply (+10V to +30V) or split-supply (±4.5V to ±20V) configurations, with logic supply (VL) configurable for TTL (5V) or CMOS (tied to V+) levels. Charge injection is guaranteed ≤10pC, critical for precision sample-and-hold accuracy and low glitch energy in multiplexed data acquisition.

Key Specifications

Pinout & Package

MAX364CSE+ is housed in a 16-pin narrow SOIC (SO-16N) package per JEDEC MS-012, 150-mil body width, with exposed pad connected to V+ per datasheet recommendation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog switch applications.

Compared with MAX364CSE+, MAX365CSE+ offers identical performance in a complementary logic state (NO vs NC), while ADG1414BRUZ trades guaranteed matching and ultra-low charge injection for lower R_ON, making it less suitable for precision sample-and-hold but viable for basic signal routing.

FAQ

What is the maximum supply voltage rating for MAX364CSE+?

The MAX364CSE+ has an absolute maximum V+ rating of 44V and V− rating of −44V, with continuous operation supported from ±4.5V to ±20V (bipolar) or +10V to +30V (unipolar). Exceeding these limits risks permanent damage, and proper sequencing (V+ first, then VL and V−) is required to avoid overstress during power-up.

Does MAX364CSE+ support TTL-level logic inputs?

Yes, MAX364CSE+ supports TTL-level inputs when VL is connected to +5V. With VL = 5V, the device guarantees logic high recognition at VINH ≥ 2.4V and logic low at VINL ≤ 0.8V. If VL is tied to V+, it operates with CMOS-compatible thresholds (VINH ≥ 70% V+, VINL ≤ 30% V+).

How does MAX364CSE+ behave when power is removed?

When all supplies (V+, V−, VL) are removed, MAX364CSE+ switches enter a high-impedance open state-no current flows between COM and NC terminals. This fail-safe behavior prevents unintended signal coupling during power-down sequences in military radios and guidance systems.

Is the exposed pad on MAX364CSE+ electrically connected?

Yes, the exposed pad on the MAX364CSE+ SO-16N package is internally connected to V+ and must be soldered to a V+ copper pour for thermal and electrical performance. Leaving it floating degrades ESD robustness and thermal dissipation, potentially affecting long-term reliability in high-temperature environments.

Can MAX364CSE+ operate with unbalanced supplies like +24V and −5V?

Yes, MAX364CSE+ supports unbalanced supplies such as +24V and −5V, provided the total V+ to V− differential does not exceed 44V and each supply remains within its absolute ratings. In such configurations, the analog signal range is limited by the smaller |V−| magnitude, e.g., −5V to +24V yields a 0–19V usable swing.
