74LVT245PW中文资料3.3 V octal transceiver with direction pin (3-state)数据手册Nexperia规格书

描述 Description

The 74LVT245 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. It features an output enable (OE) input for easy cascading and a direction (DIR) input for direction control.
