5000Vrms isolation — the safety barrier on the BOM
The DC input side accepts a forward voltage of 1.65V typical at up to 25mA forward current, and the open collector output sinks up to 15mA per channel. With a supply voltage range of 4.5V to 20V, it can interface directly with 5V logic or 12V/24V industrial rails without a level shifter.
1Mbps data rate — mid-speed isolation for fieldbus and sensor links
At 1Mbps, this optocoupler is sized for RS-485, CAN, or I2C isolation where the bus runs at a few hundred kHz to 1 MHz. The propagation delay is asymmetric — 750ns max for low-to-high, 500ns max for high-to-low — so timing margin matters if you are clocking a synchronous interface near the rate limit.
No last-time-buy notice has been issued, and there is no successor part to plan for.
Open collector output — pull-up resistor required
The open collector output means the part sinks current to ground when on, and floats when off. The 15mA sink rating is generous for most logic families, but the pull-up value sets the rise time and thus the effective data rate. At 1Mbps with a 5V rail, a 1kΩ pull-up gives a 15ns time constant, which is fine; a 10kΩ pull-up will slow the edge and may limit the rate to a few hundred kHz.
Package and footprint — 8-SMD gull wing, tube delivery
The package is an 8-SMD gull wing (8-SMD, Gull Wing per the spec), surface mount. The gull wing leads are coplanar and the package is MSL 1 typically for this class of optocoupler — no bake required before reflow as long as the moisture barrier bag is intact.
