DG508ACJ

Overview

The DG508ACJ is a monolithic CMOS analog multiplexer featuring a single 8-channel (1-of-8) configuration. It operates from dual power supplies ranging from ±4.5V to ±18V and guarantees latchup-proof construction even with input signals present during power-off conditions. The device ensures break-before-make switching and supports bidirectional signal flow. Electrical characteristics at ±15V include a maximum on-resistance of 450Ω, an off-isolation of 68dB, and a transition time of 1.0µs. Logic inputs are compatible with both TTL and CMOS standards. The component is housed in a 16-pin Plastic DIP package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Monolithic CMOS design offering low power consumption suitable for portable applications
• Guaranteed latchup-proof construction under all operating conditions
• Break-before-make switching prevents signal shorting between channels
• TTL and CMOS compatible logic and enable inputs

Applications

• Data acquisition systems
• Signal routing networks
• Control systems
• Data logging systems

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature rating. Confirm RoHS compliance status as standard plastic packages may differ from lead-free variants. Cross-reference pin configurations with official datasheets to ensure compatibility with existing PCB layouts before finalizing procurement orders.

Selection Notes

Select this component when a high-channel-count analog switch is required within a standard 16-pin footprint. Ensure the application voltage does not exceed the ±18V continuous operation limit. Verify that the 450Ω on-resistance meets system accuracy requirements. Consider alternative packages if industrial or extended temperature ranges are necessary for the deployment environment.

Part Context

This part belongs to the DG508A series of monolithic CMOS analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. It serves as a plug-in upgrade for industry-standard equivalents, providing faster enable times and lower leakage currents compared to older generations. The ACJ suffix specifically denotes the commercial temperature grade and Plastic DIP packaging format.

Replacement Considerations

DG508ABK is a documented substitute variant offering an extended temperature range of -20°C to +85°C in a CERDIP package.
