MC74ACT245DTR2G

MC74ACT245DTR2G Description

The MC74ACT245DTR2G from onsemi is a high-performance, 8-bit bidirectional transceiver designed for voltage-level translation and signal buffering in digital systems. Operating within a 4.5V to 5.5V supply range, it is part of the 74ACT series, known for its Advanced CMOS Technology (ACT) that combines TTL compatibility with low power consumption. This non-inverting transceiver features 24mA output drive capability (both high and low), making it suitable for driving heavily loaded buses. Packaged in a 20-pin TSSOP with tape-and-reel (TR) delivery, it is optimized for surface-mount applications and complies with ROHS3 and REACH environmental standards.

MC74ACT245DTR2G Features

• Bidirectional 8-Bit Interface: Enables seamless data transfer between buses with different voltage levels.
