2.5V/3.3V 16Bit bus transceiver with direction pin 3-State
DESCRIPTION
The 74ALVC1624574ALVCH16245 is a 16-bit transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions.
The 74ALVC1624574ALVCH16245 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.
The 74ALVCH16245 has active bus hold 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.
The 74ALVC16245 has 5V tolerant inputs.
