The NLV74HC244ADWR2G is a universal high speed, low power, low voltage, quad buffer with 3-state outputs. It is commonly used as a logic-level translator or as a port expander, offering 3-state outputs with low propagation delay and low power dissipation. It is used in applications such as test equipment (especially with multiple voltage levels), microcomputer-based circuits and logic circuits with multiple voltage levels.

This device has a typical speed of 5.5ns and a peak supply current of 7.5mA at 5V for all channels. It is available in a 8-pin DIP or SOIC packages and is rated for operating temperature range of -55C to 125C. The NLV74HC244ADWR2G is a dual-in-line package (DIP) device and is characterized for operation from 0°C to 70°C.

Application Field of NLV74HC244ADWR2G:

The NLV74HC244ADWR2G is used in numerous applications in which the goal is to interconnect different logic families or voltage levels. It is suitable for the bidirectional communication interface between the TTL and CMOS logic circuits. The NLV74HC244ADWR2G can be used as level shifter, translator, repeater, and driver with separate input and output voltage range. It can provide four buffered outputs of up to 15mA as well as four level-shifting/mixing outputs in the range of 3 to 15V.

It has wide applications in embedded designs, microcontroller-based products, FPGA and DSP-based systems, and communication systems. It is also an interface between the logic and analog circuits. The NLV74HC244ADWR2G can perform a variety of tasks such as data, logic, and address conversion. It is used for signal translations between TTL, LVTTL, and other logic families. It can also be used in test and measurement equipment for interfacing its I/O when signal levels must be changed.

Working Principle of NLV74HC244ADWR2G:

The NLV74HC244ADWR2G is a logic-level translator that provides a high speed and low power solution for converting between TTL and other logic families. The quad buffer works on the principle of latch operation. It has four bidirectional buffers, each having a common input and 3-state outputs. The 3-state output enable allows multiple outputs to be connected together or to other bus structures.

A logic input to any of the four channels will enable the 3-state output of that channel. The other three channels will remain in the high-impedance state. The input logic voltage of the NLV74HC244ADWR2G can range from 1.8V to 4.1V and it is capable of driving outputs from 0V to3.3V. The output enable (OE) control line can either enable or disable all channels.

The NLV74HC244ADWR2G provides wide operating temperature range from -55°C to 125°C and it is ESD protection rated. It is available in an 8-pin DIP or SOIC packages for added protection and to reduce board space consumption. The NLV74HC244ADWR2G is suitable for use in a variety of applications, such as microcontroller-based and FPGA-based designs, telecommunications applications, instrumentation circuitry, and audio/video interface markets.
