TTL models are typically implemented using bipolar transistors, which are transistors that have two PN junctions. The input of a TTL model is connected to the base of a transistor, while the output is connected to the collector. When the input is high, the transistor is turned on and the output is low. When the input is low, the transistor is turned off and the output is high.

TTL models are available in a variety of package types, including DIPs, SOICs, and QFPs. They are also available in a variety of voltage ratings, including 5V, 3.3V, and 1.8V.
