2 / 6 page 7273N-013113-2 INPUT / OUTPUT DESCRIPTION: A / B / C / D These are CMOS / TTL data inputs that can also operate with input levels up to the VDD power supply. All data input blocks contain hysteresis. 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. |
