Hi all,

I'm swapping a Teensy into a project that previously used an Arduino Uno. One of its functions was to control 32 20mA LEDs using 4 TPIC6B596N (http://www.ti.com/lit/ds/symlink/tpic6b595.pdf).

It works as expected with the Teensy 3.2 on my breadboard, but according to the datasheet:

8.4.1 Operation With V(VCC) < 4.5 (Minimum V(VCC))
This device works normally during 4.5 V ≤ V(VCC) ≤ 5.5 V, when operation voltage is lower than 4.5 V. TI can't ensure the behavior of device, including communication interface and current capability.

Has anyone used this chip and encountered odd behavior?

Thanks.
