74LVC16245AEV数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

16-bit bus transceiver with direction pin; 5 V tolerant; 3-state - The 74LVC16245A; 74LVCH16245A are 16-bit transceivers featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The device features two output enable (nOE) inputs for easy cascading and two send/receive (nDIR) inputs for direction control. nOE controls the outputs so that the buses are effectively isolated. This device can be used as two 8-bit transceivers or one 16-bit transceiver. Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices in mixed 3.3 V and 5 V applications. The 74LVCH16245A bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs.
