DG508ACJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG508ACJ+ is a monolithic CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It functions as a single 8-channel (1-of-8) switch with bidirectional signal routing capabilities. The device operates on dual power supplies ranging from ±4.5V to ±18V and supports an analog signal range of -15V to +15V. Key electrical parameters include a maximum drain-source on-resistance of 450 Ohms, a switching transition time of 1.0 µs, and a break-before-make interval of 0.2 µs. Supply current is limited to 0.2 mA at ±15V. It features latchup-proof construction and TTL/CMOS compatible logic inputs.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Monolithic low-power CMOS design ensuring symmetrical, bidirectional operation across all channels.
• Guaranteed break-before-make switching sequence prevents signal overlap during channel transitions.
• Latchup-proof construction allows continuous operation even if power supplies are removed while signals are present.
• Logic and enable inputs are fully compatible with both TTL and CMOS standards.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data-acquisition systems requiring precise signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component matches the specific package code P16-1 for the 16-pin Plastic DIP configuration. Confirm that the ordering suffix '+' indicates lead-free/RoHS compliance as per manufacturer specifications. Ensure the temperature rating aligns with the 0°C to +70°C operational range defined for the ACJ variant. Cross-reference the datasheet revision history to confirm parameter accuracy before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a single-ended 8-channel multiplexer is required within a standard 16-pin DIP footprint. The ACJ variant is suitable for commercial applications operating between 0°C and +70°C. For wider temperature ranges or surface-mount requirements, consider the ADJ or ADY variants respectively. Verify that the 450 Ohm maximum on-resistance meets the system's voltage drop and isolation requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context
