ON Semiconductor MC74ACT151D Multiplexer
The MC74ACT151D is a high-performance, single 8-input multiplexer from ON Semiconductor, designed to provide exceptional speed and power efficiency for a wide range of digital applications. This device is part of the AC/ACT series, which is renowned for its robustness and compatibility with TTL (Transistor-Transistor Logic) levels.
Constructed with advanced CMOS technology, the MC74ACT151D offers a significant advantage in terms of speed-power performance over equivalent bipolar Schottky types. Its design ensures minimal power consumption during operation, making it an ideal choice for power-sensitive designs.
The multiplexer features eight digital inputs, three select inputs, and a single output. The select inputs determine which of the eight data inputs is routed to the output. Additionally, an enable input is provided to control the state of the output. When the enable input is high, the output remains in a high-impedance state, effectively disconnecting the output from the circuit. This feature is particularly useful for implementing multiplexer arrays or for integrating the device into more complex digital systems.
The MC74ACT151D operates over a wide voltage range of 4.5V to 5.5V, which is compatible with standard 5V digital systems. Its fast switching characteristics are coupled with low quiescent current draw, which is typical of CMOS devices. The multiplexer's outputs can drive up to 24mA, providing good drive capabilities for various loads.
ON Semiconductor has packaged the MC74ACT151D in a 16-pin SOIC package, which is suitable for surface-mount technology (SMT). The compact form factor of the SOIC package allows for efficient use of board space, which is crucial in modern high-density electronic designs.
Overall, the MC74ACT151D from ON Semiconductor is a versatile and reliable component that can be used in a multitude of digital circuits, such as data routing, signal gating, and control applications. Its combination of high-speed operation, low power consumption, and SMT-friendly packaging makes it an excellent choice for designers seeking a multiplexer that balances performance and practicality.
