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 SN74LS74N is characterized for operation from 0°C to 70°C.
The SN54/74LS74A dual edge-triggered flip-flop utilizes Schottky TTL circuitry to produce high speed D-type flip-flops. Each flip-flop has individual clear and set inputs, and also complementary Q and Q outputs.Information at input D is transferred to the Q output on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level of the clock pulse and is not directly related to the transition time of the positive-going pulse. When the clock input is at either the HIGH or the LOW level, the D input signal has no effect.
