Transistor transmission logic. It is a digital circuit containing bipolar transistors connected in a certain way. TTL logic has been widely used since the early days of digital circuits. The TTL mark can appear on the input or output ports of different devices. It is used to indicate that it is a digital circuit rather than an analog circuit.
