DG407DJZ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG407DJZ is a dual 8:1 CMOS analog multiplexer manufactured by Renesas Electronics Corporation. It features two independent switching arrays, each providing eight selectable channels within a 28-pin SOIC package. The device supports single or split power supplies ranging from 5V to 34V (single) or ±5V to ±20V (dual). Key electrical specifications include a maximum on-resistance of 100 ohms, a channel-to-channel matching of 5 ohms, and a charge injection of 40 pC. Transition times are specified at a maximum of 200ns for turn-on and 150ns for turn-off. The component operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's current datasheet to confirm RoHS compliance status, as legacy listings may vary. Confirm the package type is strictly SOIC-28 and not PDIP. Check for obsolescence notices or product change notifications (PCN) regarding the manufacturing source, as this part number has been subject to label updates and potential discontinuation in certain supply chains.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 8:1 configuration is required in a surface-mount package. Ensure the application voltage does not exceed the 34V single supply limit. Verify that the 100-ohm on-resistance meets the signal integrity requirements. Compare transition times against system speed requirements, noting the 200ns maximum delay. Consider pin compatibility if replacing older DG507A series devices.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG407 series serves as a monolithic CMOS upgrade to the older DG506A/DG507A series. It integrates sixteen bilateral analog switches, a digital decode circuit, and an ENABLE input. The high-voltage silicon-gate process allows control of 30VP-P signals with ±15V supplies. The DG407DJZ specifically denotes the dual 8:1 variant in a 28-pin SOIC footprint, offering lower on-resistance variation and faster transition times than its predecessors.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

ADG407BNZ (Analog Devices Inc.) is listed as a similar replacement. DG407CJ+ and DG407DJ+ (Analog Devices/Maxim) are also cited as alternatives. Verify pinout and electrical parameter equivalence before substitution.
