A series of decoders, multiplexers, and demultiplexers of 74LS series low-power Schottky logic ICs. The 74LS series uses bipolar junction technology, coupled with Schottky diode clips to achieve the same operating speed as the original 74TTL series, but with much lower power consumption.These devices contain three independent 3-input and gates. The SN74LS83N is characterized for operation from 0°C to 70°C.
The 74LS83N is a high-speed 4-Bit binary Full Adder with internal carry lookahead. It accepts two 4-bit binary words (A1-A4, B1-B4) and a Carry Input (C0). It generates the binary Sum outputs ∑1-∑4) and the Carry Output (C4) from the most significant bit. The 74LS83N operates with either active HIGH or active LOW
operands (positive or negative logic).
