INPUT / OUTPUT DESCRIPTION:

A / B / C / D

AO / BO / CO / DO / AO / BO / CO / DO

These outputs are open-drain.

ENA

A logic low on this CMOS / TTL compatible input enables the output drivers while logic high forces them into a high-impedance state. This input is

also used to enable / disable the output short circuit thermal protection.

Applying a voltage between 7.5V and 12.5V to the ENA input will disable the thermal shutdown protection function. When using this feature, the Line

Driver Outputs are enabled but no longer protected.
