Product details

What this shunt reference does in a BOM

It can sink up to 100 mA of cathode current, making it suitable for driving optocouplers in isolated power supplies, setting reference rails in ADC circuits, or acting as a precision comparator threshold. The minimum cathode current is 700 µA, which matters for low-power bias designs where every microamp counts.

Obsolete — plan your BOM move

That means no further factory orders, no last-time-buy window, and no direct production support from TI. For an existing BOM line, you are now sourcing through independent distribution on the spot market or surplus channel. The base product number is TL432.

Field-swap realities — SOT-23-5

The SC-74A, SOT-753 package is supplied in Tape & Reel.
