Product Description

The 74VHCT245AMEL features eight bidirectional data lines that are controlled by an output-enable (OE) input, which simplifies the connection between data buses of different hierarchies and architectures. Each data direction has a dedicated input (DIR) that selects the data direction. When DIR is high, data flows from A to B, and when DIR is low, data flows from B to A.

This device is designed to be used with TTL logic levels while maintaining the speed of CMOS technology. It is capable of driving heavily loaded outputs with full fan-out capability, ensuring reliable data transmission even in demanding applications.

The 74VHCT245AMEL operates within a supply voltage range of 4.5V to 5.5V, making it suitable for interfacing with 5V systems. Its low-power consumption and fast propagation delay make it an excellent choice for high-performance, power-sensitive applications such as microprocessor or microcontroller-based systems.

With its industry-standard SOIC-20 package, the 74VHCT245AMEL is easy to integrate into a wide range of electronic circuits, offering a versatile solution for data bus interfacing needs. ON Semiconductor's commitment to quality ensures that this transceiver provides a reliable interface solution that designers can trust.
