What should engineers review before using XBL354B-TAG?

Check the 100% to 300% CTR rank at IF = 1 mA and VCE = 5 V, the 70 V collector-emitter rating, output timing requirements, and the required isolation-voltage interpretation.

What is the pinout of XBL354B-TAG?

Use the XBL354B-TAG datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about XBL354B-TAG pinout to locate pins, power rails, and interface signals before layout.

AI summary

XBL354B-TAG is a 4-pin SOP phototransistor optocoupler with antiparallel LED input, intended for AC-response isolation applications. The B rank specifies 100% to 300% CTR under the stated test conditions.

Best for

AC line monitoring
Unknown-polarity DC sensing
Telephone line interfaces

Avoid if

A tightly controlled CTR across temperature is required without circuit margin
A package other than SOP-4 with 2.54 mm lead pitch is required

Check before use

Validate CTR at the intended LED drive current and temperature.
Confirm creepage, clearance, and applicable safety-isolation requirements at system level.
