The 74LVC16244AEV is part of the family of Logic, Buffers, Drivers, Receivers, Transceivers and it is used for a variety of applications. This device is a low–voltage 3–state Octal Bus Transceiver with bidirectional data–flow and direction–control. This makes it the ideal solution for interfacing different voltages, clocking varieties and bus directions.

The 74LVC16244AEV is a 16–pin, 3.3V compatible logic that contains two bus transceivers with four input/output ports per side. The A and B sides of the device can provide bidirectional voltage translation between TTL and CMOS–level logic. The devices have separate output–enable inputs (OE and OEA) to permit data flow in both directions.

The active–low enables allow both sides to be enabled with the OE input, or the two sides can be independently enabled by using the output–enable A and output–enable B inputs. The device achieves a high bandwidth, which makes it suitable for a variety of high–frequency, low–voltage applications.

Additionally, the device has a power–down control that allows the user to put the device into a low–power standby mode with only minimal electric current. This feature improves the power savings and system reliability. The device also has two select inputs (–I and +I) to determine whether the A side or the B side is enabled.

The 74LVC16244AEV is commonly used in creating bus–to–bus bridges, providing 4-bit communication between two buses and applications dealing with clocking requirements. The device is best suited for applications such as computer peripherals, synchronous communications, storing and retrieving data, as well as securing information.

When it comes to its working principle, the 74LVC16244AEV relies on two transceivers. Each transceiver consists of bidirectional gates that are controlled by the output–enable A (OEA) and output–enable B (OEB) inputs to provide outputs in the two directions. When the output–enable A or output–enable B inputs are high (1), the A and B ports are enabled, allowing data to flow freely between the two buses. When the output–enable A and output–enable B inputs are low (0), both ports are disabled, preventing data from passing through.

The 74LVC16244AEV also has an active–low control input (E) that allows the user to put the device into a low–power standby mode with minimal electric current. When in standby mode, all output ports are in the high–impedance state, thus reducing power consumption. The select inputs (–I and +I) determine which side of the device is enabled by either the OEA or the OEB input.

Overall, the 74LVC16244AEV is a powerful, low–voltage logic device that is used in a variety of applications. It is perfect for bus–to–bus bridges, providing 4-bit communication between two buses, and applications requiring clocking requirements. With an active–low control input, the device can be put into a low–power standby mode, reducing its power consumption, and it has two select inputs that allow the user to enable either side of the device.
