SN74LS251 - TTL logic IC Transistor, DIP16


Transistor–Transistor Logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors. TTL is notable for being a widespread integrated circuit (IC) family used in many applications such as computers, industrial controls, test equipment and instrumentation, consumer electronics, synthesizers, etc. The designation TTL is sometimes used to mean TTL-compatible logic levels, even when not associated directly with TTL integrated circuits, for example as a label on the inputs and outputs of electronic instruments.

The 74xx series of transistor-transistor logic (TTL) integrated circuits are historically important as the first widespread family of TTL integrated circuit logic.

The 74LS family (Low Power Schottky) of ICs is a lower-power version of the 74S family, with slightly higher speed but lower power dissipation than the original 74 family.
