74ACT245SJ: Octal Bidirectional Transceiver from ON Semiconductor
The 74ACT245SJ is a high-performance, octal bidirectional transceiver designed by ON Semiconductor for asynchronous communication between data buses. This integrated circuit is part of the 74ACT series, which is known for its high-speed CMOS technology, offering robust performance and reliability for a wide range of digital applications.
The device allows bidirectional data flow with individual direction controls for each of the eight channels. Each byte has a separate Output Enable (OE) that must be low to enable the device's outputs. When the Output Enable is high, the outputs are in a high impedance state, which is particularly useful in preventing data contention on the bus.
Furthermore, the 74ACT245SJ is characterized by its low power consumption, making it an excellent choice for battery-operated and power-conscious applications. The device operates over a wide voltage range from 4.5V to 5.5V, providing compatibility with standard 5V systems while maintaining the flexibility to work with various logic levels.
Key features of the 74ACT245SJ include:
- Eight bidirectional data lines
- Separate input and output direction controls for each channel
- Separate Output Enable for each byte
- High impedance outputs when OE is high
- Low power consumption
- Operating voltage range of 4.5V to 5.5V
- High noise immunity characteristic of CMOS devices
- Industry-standard SOIC package for easy integration
The 74ACT245SJ is available in a compact SOIC package, which is ideal for space-constrained applications. It is commonly used in interfacing applications, data communication systems, and anywhere where data must be transferred between two buses without signal degradation.
ON Semiconductor's commitment to quality ensures that the 74ACT245SJ meets the stringent requirements of modern digital systems. Whether used in commercial, industrial, or automotive environments, this transceiver provides a reliable solution for high-speed bidirectional data transfer.
