Part Number: TDA4VM
The TDA4VM dig output pin for VCC 3.3V is specified in table 7-9 to be for low level worst case 0.4V and for high level worst case 2.4V. According to the table description this is over the full range, so full load current and full temp.
Do we have chart of the low and high levels versus the load current.? My customer is using a logic behind the out pin that would be violated with the 0.4V and 2.4V levels, but it is driving <=1mA instead of the allowed 5 and 6mA.
