ON Semiconductor MC74AC138DTR2 Decoder/Demultiplexer
The MC74AC138DTR2 is a high-performance, integrated circuit designed and manufactured by ON Semiconductor, a leader in energy-efficient innovations. This device is a 3-to-8 line decoder/demultiplexer that features advanced silicon-gate CMOS technology, which provides superior speed and electrical performance compared to traditional bipolar technology.
Featuring a wide operating voltage range of 2V to 6V, the MC74AC138DTR2 is suitable for a variety of applications across different voltage requirements. Its low power consumption and high noise immunity characteristic of CMOS technology make it an ideal choice for battery-operated and noise-sensitive electronic systems.
The decoder/demultiplexer has three binary select inputs (A0, A1, A2), an enable input (E), and eight mutually exclusive outputs (Y0 to Y7). When the enable input is high, all outputs are forced to a low state. When the enable input is low, the binary select inputs determine which single output will be high, thus directing the input signal to the selected output line. This makes the MC74AC138DTR2 perfect for implementing decoder functions in microprocessor-controlled systems where chip select signals are required.
The MC74AC138DTR2 comes in a TSSOP-16 package, which is a space-saving and weight-conscious packaging option, suitable for surface-mount technology (SMT) and providing excellent thermal performance. The device is also available in a range of other package options to suit different assembly and application requirements.
Applications for the MC74AC138DTR2 are diverse and include but are not limited to:
- Memory chip select decoding
- Data routing
- Control signal generation
- Function generator selection
- Input/output expansion
ON Semiconductor's commitment to quality ensures that the MC74AC138DTR2 meets the stringent standards required for industrial, commercial, and consumer use. The device's robust design and manufacturing process make it a reliable component for your digital logic needs, providing a combination of versatility, efficiency, and performance.
