74LVT2245D,118

The 74LVT2245; 74LVTH2245 is a high-performance BiCMOS product designed for VCC operation at 3.3 V. This device is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features an output enable input for easy cascading and a direction input (DIR) for direction control. The 74LVT2245; 74LVTH2245 is designed with 30 ? series resistance in both the HIGH-state and LOW-state of the output. This design reduces line noise in applications such as memory address drivers, clock drivers and bus transceivers and transmitters.
