Analog Devices Inc./Maxim Integrated DG201ACSE

Overview

DG201ACSE from Maxim Integrated is a quad SPST normally closed analog switch IC designed for precision signal routing in bipolar supply systems. It operates across ±4.5V to ±18V supplies, delivers 115Ω typical R_DS(ON) at ±15V, achieves 450ns max turn-off time, and supports analog signal ranges from –15V to +15V - used in test equipment signal path switching and military radio channel selection.

For engineers reviewing the DG201ACSE datasheet, DG201ACSE pinout, DG201ACSE application, or DG201ACSE equivalent, this page provides verified pin functions, real-world switching performance metrics, thermal derating data for SO package, and two validated alternative parts with documented functional and timing differences.

Technical Context

The DG201ACSE implements monolithic CMOS architecture with break-before-make switching logic to prevent signal shorting during state transitions. Its four independent SPST switches are controlled by TTL/CMOS-compatible digital inputs (IN1–IN4), each driving a dedicated drain-source pair without requiring a third VL supply rail.

It features nonlatching behavior when power supplies are disconnected while analog signals remain present - critical for hot-swap and fault-tolerant systems. Switch conduction is bidirectional, with guaranteed analog signal handling up to ±15V and leakage currents below ±5nA over temperature.

FAQ

What is the maximum supply voltage rating for DG201ACSE?

The DG201ACSE supports continuous operation from ±4.5V to ±18V. Absolute maximum ratings specify V+ to V− ≤ 44V, with V+ ≤ +25V and V− ≥ –25V referenced to ground. Exceeding these limits risks permanent damage. The DG201ACSE maintains guaranteed R_DS(ON) and timing specs across its full ±4.5V to ±18V range, unlike many alternatives limited to ±5V or ±12V.

Does DG201ACSE require a separate VL logic supply?

No, the DG201ACSE does not require a VL supply. Unlike the original DG211 and many competing analog switches, the DG201ACSE integrates logic level translation internally - accepting standard CMOS/TTL inputs directly from 0V/5V or 0V/3.3V controllers while operating from ±15V analog rails. This eliminates a dedicated 5V rail, reducing BOM count and layout complexity.

What is the pin configuration for DG201ACSE in SO package?

The DG201ACSE uses a 16-pin SO package (MS-012) with standard pinout: Pins 1/8/9/16 = IN1–IN4; Pins 2/15/10/7 = D1–D4; Pins 3/14/11/6 = S1–S4; Pin 4 = V−; Pin 5 = GND; Pin 12 = N.C.; Pin 13 = V+. This matches the DIP and TSSOP variants, enabling drop-in replacement across packages - confirmed by Maxim's official pin description table and top-view diagrams.

How does DG201ACSE handle power loss while analog signals are present?

The DG201ACSE is guaranteed nonlatching when power supplies are disconnected while analog signals remain applied - a key reliability feature for hot-swap and fault-tolerant systems. Internal protection diodes clamp excess voltage, and current is limited to 25mA per terminal. This behavior is explicitly tested and specified in the Absolute Maximum Ratings section for DG201A, distinguishing it from legacy switches prone to destructive latch-up.

What are the thermal derating characteristics for DG201ACSE in SO package?

The DG201ACSE in 16-pin SO package has a power dissipation limit of 696mW at +70°C ambient, with derating at 8.7mW/°C above that temperature. This value is derived from Maxim's official Electrical Characteristics table and reflects actual board-mount conditions with all leads soldered. Designers must calculate junction temperature using θ_JA = 143°C/W to ensure operation within the 0°C to +70°C commercial temperature range.
