Analog Devices Inc./Maxim Integrated DG211CSE+T

Overview

DG211CSE+T from Maxim Integrated is a quad SPST normally closed analog switch IC designed for bidirectional signal routing in ±4.5V to ±18V dual-supply systems. It features guaranteed break-before-make switching, 175Ω max R_DS(ON) at ±15V, 1000ns max turn-on time, and operates across 0°C to +70°C - used in PBX systems and test equipment where rail-to-rail analog signal integrity and supply-disconnect robustness are required.

For engineers reviewing the DG211CSE+T datasheet, DG211CSE+T pinout, DG211CSE+T application, or DG211CSE+T equivalent, key selection criteria include analog signal range (±15V), leakage performance (±5nA ID(OFF)), ON-resistance matching across channels, absence of VL supply requirement, and SO-16 package compatibility with legacy DG211 designs.

Technical Context

The DG211CSE+T implements monolithic CMOS switch architecture with four independent SPST switches, each controlled by TTL/CMOS-compatible logic inputs (IN1–IN4). Its internal design eliminates the third VL supply required by earlier DG211 variants, simplifying power architecture while maintaining latch-up immunity during hot-insertion scenarios.

Switching behavior is characterized by guaranteed break-before-make timing, with t_ON ≤ 1000ns and t_OFF ≤ 500ns under 1kΩ/35pF load conditions. Analog path performance is specified over full ±15V signal swing, with channel capacitance (CD+S(ON)) at 16pF and OFF-isolation ≥70dB at 100kHz.

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

Compared with MAX4617ESE+ and ADG1412BRUZ, the DG211CSE+T uniquely delivers ±18V dual-supply operation without VL, making it the only option among the three that maintains full rail-to-rail analog switching capability while eliminating a dedicated logic supply rail.

Availability

DG211CSE+T is available at Aetrix Electronics and suitable for PBX systems, test equipment, Winchester disk drives, and military radios requiring stable component supply across commercial temperature grades.

Supply support for DG211CSE+T includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a U.S.-based semiconductor company specializing in high-performance analog, mixed-signal, and power management ICs for industrial, communications, and computing markets.

The DG211CSE+T belongs to Maxim's legacy analog switch product line, engineered for robust signal routing in dual-supply environments where supply sequencing resilience and rail-to-rail analog fidelity are essential.

FAQ

What is the maximum analog signal voltage range supported by the DG211CSE+T?

The DG211CSE+T supports an analog signal range of ±15V when operated with ±15V supplies. This is specified in the Electrical Characteristics table under VANALOG, and applies across the full 0°C to +70°C operating temperature range. The device remains functional within ±4.5V to ±18V supply rails, but analog signal swing is limited by the actual V+ and V− voltages applied.

Does the DG211CSE+T require a separate VL logic supply voltage?

No, the DG211CSE+T does not require a VL supply. Unlike earlier DG211 versions from the original manufacturer, Maxim's DG211CSE+T integrates logic-level translation internally, accepting standard CMOS/TTL inputs directly from 0V/2.4V logic without any auxiliary voltage rail - a key differentiator confirmed in the Features section and Ordering Information tables.

What is the guaranteed switching timing for the DG211CSE+T?

The DG211CSE+T guarantees a maximum turn-on time (t_ON) of 1000ns and maximum turn-off time (t_OFF) of 500ns under standard test conditions (V+ = +15V, V− = −15V, RL = 1kΩ, CL = 35pF). These values are explicitly listed in the DG211-specific Electrical Characteristics table and distinguish it from the faster DG201A variant.

How does the DG211CSE+T prevent latch-up when power supplies are disconnected?

The DG211CSE+T is designed to be nonlatching: it will not enter a destructive high-current state even when V+ and V− are turned off while analog input signals remain present. This behavior is guaranteed per the General Description and Absolute Maximum Ratings, and stems from its monolithic CMOS process and internal protection structure - critical for hot-swap and fault-tolerant systems.

What package type is used for the DG211CSE+T?

The DG211CSE+T uses a 16-pin small outline integrated circuit (SOIC) package, also referred to as SO-16 or narrow SO. Its mechanical dimensions conform to JEDEC MS-012, with 3.9mm body width and 1.27mm lead pitch, as documented in the Package Information section and Ordering Table entry "DG211CSE".
