DG508ACJZ

Overview

The DG508ACJZ is a CMOS monolithic 8-channel analog multiplexer manufactured by Renesas Electronics Corporation. It operates within a temperature range of 0°C to +70°C and is housed in a 16-lead PDIP package. The device supports dual power supplies ranging from ±4.5V to ±18V, with a maximum supply rating of 44V. Key electrical parameters include a typical drain-source on-resistance (rDS(ON)) of 270Ω at +10V and 230Ω at -10V, with a maximum of 450Ω for the 'C' suffix. Switching times are typically 0.6µs, while enable turn-on time reaches up to 1.5µs. Power consumption is low, with positive supply current typically at 1.3mA.

Feature Summary

• TTL and CMOS-compatible address and enable inputs for direct logic interfacing
• High latch-up immunity ensuring reliable operation under transient conditions
• Break-before-make switching mechanism prevents signal shorting during channel transitions
• Pb-free construction compliant with RoHS standards

Applications

• Data acquisition systems
• Communication systems
• Signal multiplexing and demultiplexing
• Audio signal multiplexing

Procurement Notes

Verify that the component matches the specific 'C' suffix temperature grade (0°C to +70°C) required for your application environment. Confirm the package type is the standard 16-lead PDIP variant. Ensure the supplier provides documentation confirming Pb-free status and RoHS compliance as specified in the ordering information section of the datasheet.

Selection Notes

Select this part when an 8-channel analog switch is needed with TTL/CMOS compatibility. The 'C' suffix is suitable for commercial applications operating between 0°C and +70°C. For military or industrial environments requiring wider temperature ranges, consider the 'A' (-55°C to +125°C) or 'B' (-25°C to +85°C) suffixes instead. Verify that the 450Ω maximum on-resistance meets your signal integrity requirements.

Part Context

The DG508A series includes variants such as the DG506A (16-channel), DG507A (dual 8-channel), and DG509A (dual 4-channel). These devices share similar architectural features but differ in channel count and configuration. The DG508A specifically provides a single 8-channel array, making it distinct from the differential configurations found in other series members.

Replacement Considerations

The datasheet explicitly recommends the DG408 as the replacement part for new designs. The DG408 offers improved performance characteristics, including lower on-resistance and faster transition times, while maintaining pinout compatibility.
