74AVC16244DGG,112 belongs to Logic - Buffers, Drivers, Receivers, Transceivers category. It is an eight-bit low-voltage (3.3V) transceiver with 2-bit direction control. It has two state-maintained transceivers with 1/8th unit load. It has two ports, A and B, and each port has eight bidirectional I/O lines.

The application field of 74AVC16244DGG,112 includes but not limited to:

• Communication equipment processors, memory and interface circuits
• Power supply and power management circuits
• Computer and microcomputer peripherals
• Short- and long-haul multi-channel communications
• Networking and telecom systems
• Data acquisition and control systems
• Consumer and industrial systems
• Computer and electronics applications

The working principle of 74AVC16244DGG,112 is as follows:

The transceiver has two 2-bit direction control inputs. INEA and INEB determine the directivity of the bi-directional ports A and B respectively. When INEA and INEB are both set to LOW, the devices at port A are inputs and the devices at port B are outputs. When INEA and INEB are both set to HIGH, port B devices are inputs, and port A devices are outputs. Three other two-bit states (INEA HIGH and INEB LOW, INEA LOW and INEB HIGH, INEA and INEB both HIGH) are open, which means the port I/O states can not be determined in these states.

The 74AVC16244DGG,112 utilizes latch-type input buffers for CMOS inputs, so that its inputs are both TTL- and CMOS-compatible. It has an output latch for remembering data. When changing direction, the data can be quickly transferred from the input latch to the output latch. It has ESD protection for its inputs and outputs, to prevent the device from being damaged by the ESD.

The 74AVC16244DGG,112 transmits data with synchronizing clocks. When the data at the input is valid, the device is ready to receive the clock and starts the reception process. It has a differential output driver with programmable output drive currents, which can reduce power consumption and ground bounce.

The 74AVC16244DGG,112 has a fail-safe feature, which ensures that all outputs, except the active outputs, are in a defined logical state when the device is disabled or unloaded.
