DUAL 5-INPUT NOR GATE
The 74LS26 is a 14-pin, low-power, low-noise, high-speed, quad 2-input exclusive-OR gate logic IC from Texas Instruments. It is a member of the 74xx series of logic ICs. Description: The 74LS26 is a quad 2-input exclusive-OR gate logic IC. It has four independent gates, each of which performs the logic function of an exclusive-OR gate. Each gate has two inputs and one output. The output of each gate is high when either, but not both, of its two inputs are high. Features: Low power consumption Low noise High-speed operation High noise immunity Wide supply voltage range Low input current Applications: The 74LS26 can be used in a variety of applications, including logic circuits, data processing, memory decoding, and arithmetic operations. It is also useful in applications such as multiplexers, decoders, and parity generators.
