The DG409CY+T is a dual 4-channel analog multiplexer/demultiplexer manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

Specifications:

• Configuration: Dual 4-channel (2x SPDT)
• Supply Voltage Range: ±4.5V to ±20V (Dual Supply), +4.5V to +34V (Single Supply)
• On-Resistance (RON): 85Ω (Typical)
• Charge Injection: 10pC (Typical)
• Switching Time (tON/tOFF): 300ns / 200ns (Typical)
• Operating Temperature Range: -40°C to +85°C
• Package: 16-pin SOIC (CY suffix)
• Logic Compatibility: TTL/CMOS

Descriptions:

• The DG409CY+T is a high-performance, low-leakage CMOS analog switch designed for precision signal routing.
• It integrates two independent 4-channel multiplexers/demultiplexers, allowing bidirectional signal flow.
• Suitable for industrial, medical, and communication systems requiring low distortion and high accuracy.

Features:

• Low RON (85Ω typical) for minimal signal attenuation.
• Low charge injection (10pC) for reduced switching transients.
• Wide supply voltage range (±4.5V to ±20V or +4.5V to +34V).
• TTL/CMOS-compatible logic inputs for easy interfacing.
• Break-before-make switching to prevent signal contention.
• High off-isolation (-80dB at 1MHz) for minimal crosstalk.

This device is ideal for applications such as data acquisition, test equipment, audio switching, and automated test systems.
