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 SN74LS02N is characterized for operation from 0°C to 70°C.
