Overview
The DG407BDJ is a dual-channel CMOS analog multiplexer manufactured by Vishay Siliconix, housed in a 28-pin PDIP package. It selects one of eight differential input channels for connection to a common differential output. The device operates on single or dual power supplies ranging from 7.5 V to 36 V, with a maximum dual supply voltage of ±20 V. Key electrical parameters include a maximum on-resistance of 100 Ohms, a maximum turn-on time of 125 ns, and a maximum turn-off time of 94 ns. It supports a maximum power dissipation of 625 mW and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Provides break-before-make switching action to prevent input short circuits during channel transitions.
- Features TTL-compatible control inputs, address lines, and enable functions across the operating temperature range.
- Supports bidirectional current flow and blocks voltages up to the power rails in the off state.
Applications
- High-speed data acquisition systems
- Audio signal routing and switching
- Automated test equipment (ATE)
- Avionics applications
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status as indicated in official documentation, noting that specific suffixes may affect environmental certification. Validate pinout compatibility with existing PCB layouts before integration.
Selection Notes
Select this component when differential signal routing is required with high voltage tolerance. Ensure the design accommodates the 100 Ohm on-resistance and 125 ns switching speed. Verify that the system power supply falls within the 7.5 V to 36 V range and that thermal management supports the 625 mW dissipation limit in the target environment.
Part Context
This part belongs to the DG406/DG407 series of high-performance CMOS analog multiplexers. It shares architectural similarities with the DG406 but differs in handling differential signals rather than single-ended inputs. The series utilizes a 44V silicon gate CMOS process designed to prevent latch-up and support wide voltage ranges.
Replacement Considerations
Publicly documented alternatives include the DG407DW-E3 for surface mount applications. Verify pin compatibility and electrical specifications against the original datasheet before substitution.
