transistor-transistor logic (TTL) integrated circuit family that uses bipolar transistors as the main switching elements. It was the most common type of logic family used in computers from the 1960s to the 1980s.
The output 0 and 1 levels for TTL logic family are approximately 0.6 and 3.5 V, respectively. This means that a voltage of 0.6 V or less is considered a logic 0, while a voltage of 3.5 V or more is considered a logic 1.
The other options are incorrect. Option A is incorrect because the output 0 level is not 0.1 V. Option C is incorrect because the output 1 level is not 1.75 V. Option D is incorrect because the output 0 level is not -1.75 V, and the output 1 level is not -0.9 V. Option E is incorrect because the output 0 and 1 levels are not 0.1 V and 5 V, respectively.
