Product Description

The SN74AHCT245IDBRSV is designed to be used in bidirectional asynchronous communication systems. The device's eight channels can be independently directed in either direction by DIR input, providing flexibility in connecting different bus architectures. The outputs can be put into a high-impedance state (off-state) to effectively disconnect the bus lines.

Constructed with advanced silicon-gate CMOS technology, it achieves high-speed operation while maintaining the CMOS low power dissipation. This transceiver is compatible with TTL inputs and operates in a voltage range of 4.5V to 5.5V, making it suitable for interfacing with 5V systems.

Its wide operating temperature range of -40°C to 85°C and the small SSOP-20 package make this transceiver a versatile choice for various applications, including telecommunications, computing systems, and industrial controls where space is at a premium and reliable data transfer is essential.

With its industry-standard footprint, the SN74AHCT245IDBRSV is easy to integrate into existing designs, providing a straightforward solution for enhancing data bus communication with minimal redesign required.
