This document describes the features and characteristics of the M54HC7245/7640/7643/7645 and M74HC7245/7640/7643/7645 models. They are high-speed, low-power, octal bus transceivers with high noise immunity. These devices are intended for two-way asynchronous communication between data buses, and the direction of data transmission is determined by the DIR input. The HC7245/640/7643/7645 have the same pin configuration and function as the HC245/640/643 and they have a hysteresis characteristics with each input, so they can be used as a line receiver, etc.
