74ALVCH16245DL NRND

16-bit transceiver with direction pin; 3-state

The 74ALVC16245; 74ALVCH16245 is a 16-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions.

The 74ALVC16245; 74ALVCH16245 features two output enable inputs (pins nOE) for easy cascading and two send or receive inputs (pins nDIR) for direction control. Pins nOE control the outputs so that the buses are effectively isolated. This device can be used as two 8-bit transceivers or one 16-bit transceiver.

The 74ALVCH16245 has an active bushold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.
