Procurement Notes
Verify the specific suffix 'V' against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm that the part status remains acceptable for your design timeline, as availability may vary. Ensure the 16-SSOP footprint matches your PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when four isolated channels are required within a single compact package. Compare the 40 V collector-emitter voltage limit against your circuit's peak voltages. Verify that the 100% minimum current transfer ratio meets your logic level requirements for reliable switching performance in noisy environments.
Part Context
This part belongs to the PS2811 series of transistor output optocouplers from Renesas Electronics. It is designed for general-purpose isolation applications where space efficiency and high reliability are critical. The series offers various channel configurations and package options to suit different system integration needs.
