The SN74AVC16244DGGR is a high performance octal bus transceiver buffer with non inverting 3-State outputs. It is designed for bidirectional bus line application where high speed and low power waveforms are needed and the direction of data flow is controlled by an active low output enable line. It consists of two separate uni-transceivers that can be used to separate two different bus systems.

This device is also known as a bidirectional level shifter, which makes it ideal for communication between I/O interface circuits operating at different voltage levels. It is suitable for use in high speed applications. Typical applications include level shifting and data rate matching between I/O interfaces, memory systems, microprocessors, and peripherals.

The SN74AVC16244DGGR logic buffer has multiple features that make it suitable for use in many different areas. It has signal handling capability with low input and output capacitance for fast switching speed, low signal distortion, and low overall power consumption. This makes it suitable for high speed signal handling applications.

The SN74AVC16244DGGR transceiver has non-inverting high speed outputs and non-inverting low level inputs. This makes it suitable for both parallel and serial data applications. It also has active LOW output enable PINs (OE), which allows the user to control the direction of data flow. It also has two separate overload detection circuits for overcurrent protection.

The SN74AVC16244DGGR transceiver has an operating voltage range of -2.0V to 7.0V and an output drive capability of -25mA (max) and 25mA (max). It is also capable of operating with a frequency Range up to 50MHz. It is offered in various packages such as PQFN, TSSOP, and VSSOP.

The SN74AVC16244DGGR transceiver works in three different modes, the active LOW (Mode 0), the active HIGH (Mode 1), and the disabled (MODE 2). In the active LOW mode, data is transferred from the input to the output by the active LOW output enable, and when enabled, the output signal will match the input signal. In the active HIGH mode, data is transmitted from the output to the input by the active HIGH output enable, and when enabled, the output signal does not change.

In the disabled mode (MODE 2), the output enable line is set to a high level impedance, and no data can be transferred between the input and output. When both the input and output enable lines are low, the output signal is disabled, and no data can be transmitted either way. This mode is useful when the user wants to isolate the data flow direction and also to prevent any damage if the lines get shorted.

In conclusion, the SN74AVC16244DGGR transceiver buffer is a high performance logic buffer that offers fast switching speed, low power consumption and low input and output capacitances. It is suitable for multiple applications, such as level shifting, data rate matching and providing isolation of data lines. It can operate in three different modes and is available in various packages.
