The SN74LVC16T245DGGR is a 16-bit dual-supply Bus Transceiver with configurable level-shifting or voltage translation. The SN74LVC16T245 device is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode. The device transmits data from the A-bus to the B-bus when the B-port outputs are activated and from the B-bus to the A-bus when the A-port outputs are activated. The input circuitry on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ.
Control inputs VIH/VIL levels are referenced to VCCA voltage
Overvoltage-tolerant inputs and outputs allow mixed voltage-mode data communications
