The SN74LS355DW is an integrated circuit (IC) component that belongs to the family of SN54/74LS series of TTL logic. It is a Dual 1-of-4 multiplexer with 3-STATE outputs, which means it can select one out of four inputs and provide the output accordingly. Here is an overview of its key features and functionalities:
1. Dual 1-of-4 Multiplexer: The SN74LS355DW contains two independent multiplexers, each capable of selecting one out of four inputs based on control signals.
2. TTL Logic: It operates on TTL (Transistor-Transistor Logic) levels, making it compatible with various digital systems.
3. 3-STATE Outputs: The outputs of both multiplexers are 3-STATE outputs. This means that they can be actively driven high or low, or they can be in a high-impedance state (disconnected) depending on the control signals.
4. Common Select Inputs: Both multiplexers share common select inputs, which determine the output selection. The control signals are labeled as S0 and S1, enabling the selection of four different combinations.
5. Schottky-Clamped for High-Speed Operation: The IC is designed with Schottky clamps on all inputs, ensuring high-speed performance and minimal propagation delay.
6. Wide Operating Voltage Range: The SN74LS355DW can operate within a wide voltage range, typically from 4
