Overview
The DG407BDN-T1 is a dual 8-channel high-performance CMOS analog multiplexer manufactured by Vishay Siliconix. It selects one of eight differential inputs to a common differential output using a 4-bit binary address. The device operates within a temperature range of -40 °C to +85 °C and utilizes a 28-pin PLCC package. Key electrical specifications include a maximum on-resistance of 74 Ω, a transition time of up to 161 ns, and an off-isolation of -86 dB at 1 MHz. It supports single supply voltages from 5 V to 40 V or dual supplies from ±5 V to ±20 V.
Feature Summary
- Break-before-make switching action prevents momentary shorting of inputs during channel transitions.
- TTL and CMOS compatible control inputs ensure compatibility with standard logic families across the full operating temperature range.
- Epitaxial layer construction prevents latch-up associated with older CMOS technologies.
- Enable (EN) function allows resetting all switches to the off state for stacking multiple devices.
Applications
- High-speed data acquisition systems
- Audio signal switching and routing
- Automatic test equipment (ATE)
- Medical instrumentation
Procurement Notes
Verify that the specific part number matches the required package type and suffixes. Confirm RoHS compliance status if lead-free terminations are mandatory for the assembly process. Ensure the ordering quantity aligns with the manufacturer's tape and reel packaging requirements.
Selection Notes
Select this component when differential signal routing is required in a compact form factor. Verify that the maximum supply voltage does not exceed 44 V between rails. Check that the charge injection and on-resistance values meet the precision requirements of the target application circuit.
Part Context
This device belongs to the DG406B/DG407B series of monolithic CMOS analog multiplexers. It serves as a drop-in replacement for legacy DG506A and DG507A devices while offering improved performance metrics such as lower on-resistance and faster transition times.
Replacement Considerations

FAQ
What is the purpose of the break-before-make switching action?
It protects against momentary shorting of inputs by ensuring the current path is fully disconnected before a new connection is established.
How does the Enable (EN) pin function?
The EN input allows the user to reset the multiplexer to all switches off, which facilitates the stacking of several devices on a common bus.
Is the device suitable for single-supply operation?
Yes, the DG407B supports single supply operation ranging from 5 V to 40 V, in addition to dual supply configurations.
