Product Description

The CD74ACT245M is optimized for use in applications that require high-speed data transfer and low power consumption. With its wide operating voltage range of 4.5V to 5.5V, it is compatible with TTL environments, and its bus transceiver function is essential for effective data communication between two buses which can operate independently of one another.

This device features eight bidirectional input/output (I/O) ports (A1-A8 and B1-B8) that can be controlled by the direction control (DIR) input. The direction control determines the data flow direction, either from A to B or B to A. In addition, the output enable (OE) input can disable the device's outputs to place them in a high-impedance state, which is particularly useful in preventing bus contention.

Manufactured with Texas Instruments' advanced BiCMOS technology, the CD74ACT245M offers reduced power consumption without sacrificing speed. This makes it an excellent choice for interfacing with microprocessors or microcontrollers and for use in systems that require a robust level of performance in terms of speed and power efficiency.

The device comes in a space-saving 20-pin SOIC package, making it suitable for compact PCB layouts and high-density applications. With its industry-standard footprint, the CD74ACT245M is easy to integrate into a wide range of electronic systems, including computing, networking, and industrial devices.
