Key Features
- 6 independent isolation channels in a compact 16-pin SSOP-16 package for space-efficient board layouts
- Wide supply voltage range of 2.25 V to 5.5 V on both VCC1 and VCC2 rails, enabling 3.3 V and 5 V mixed-voltage system compatibility
- High-voltage galvanic isolation barrier with low propagation delay for fast digital signal transmission across isolation boundaries
- Pb-free, JEDEC e4 compliant construction suitable for lead-free manufacturing and environmentally regulated markets
Applications
The ISO7761DBQ is used in industrial motor drives, power converters, and programmable logic controllers where 6 digital signals must cross a galvanic isolation barrier between a 2.25 V to 5.5 V microcontroller domain and a high-voltage power stage. It also serves in medical equipment and grid-tied inverters to protect sensitive logic circuits from transient surges of several kilovolts. The 16-pin SSOP package allows compact PCB integration alongside gate drivers and sensor interface circuits.

Frequently Asked Questions
How many channels does the ISO7761DBQ provide and what supply voltage range does it support?
The ISO7761DBQ integrates 6 independent digital isolation channels within a single 16-pin SSOP package. Both VCC1 and VCC2 supply pins accept voltages from 2.25 V to 5.5 V, making the device fully compatible with 3.3 V and 5 V logic families without level-shifting circuitry. This broad supply range simplifies mixed-voltage system design in industrial and automotive applications.
In which industrial isolation applications is the ISO7761DBQ a strong fit?
The ISO7761DBQ excels in motor drive gate-driver interfaces, field-bus repeaters, and PLCs where 6 digital control signals must cross a galvanic isolation barrier with low propagation delay. The 16-pin SSOP-16 package fits within compact PCB areas alongside power transistor drivers, and the 2.25 V to 5.5 V supply range accommodates both the 3.3 V microcontroller domain and the 5 V gate-driver domain in a single device.
How does the ISO7761DBQ compare to a 4-channel isolator when board space is tight?
The 6-channel ISO7761DBQ replaces up to two 4-channel isolators and eliminates a second package footprint, freeing roughly 30 mm² of PCB area in a 16-pin SSOP outline. Consolidating 6 isolated paths into one device also reduces BOM count and simplifies power supply routing by requiring only two supply rails at 2.25 V to 5.5 V rather than four. This trade-off favors the ISO7761DBQ whenever 5 or 6 isolation channels are needed simultaneously.
What package does ISO7761DBQ use and is it compatible with standard lead-free PCB assembly?
ISO7761DBQ is housed in a 16-pin SSOP (R-PDSO-G16) plastic-epoxy package with a body width of approximately 5.3 mm and 0.65 mm pin pitch. The device is Pb-free and JEDEC JESD-609 e4 compliant, qualifying it for standard 260°C peak lead-free reflow assembly. The SSOP-16 outline is compatible with common SMT land patterns and can be placed by standard pick-and-place equipment.
