SN74LVC244AZQNR is a low voltage, high performance buffer and line driver with a bus hold designed for AC and/or DC applications. It is part of the Texas Instruments (TI) Low Voltage Bus (LVC) family, which includes transceivers, receivers, drivers, buzzers, and input/output ports. This product is best suited for interfacing to FPGA or CPLD devices, when not powering the load. The SN74LVC244AZQNR device is a low-voltage, low-power octal buffer and line driver designed for both asynchronous (AC) and synchronous (DC) applications. It features bus hold for temperature-stable interface, bus hold for low power dissipation, data output enable for bus-hold expansion, reduced EMI/RFI emissions, and high noise immunity.

The SN74LVC244AZQNR operates with dual power supplies. It is designed to use both the positive supply (VDD+) and the negative supply (GND−). This provides high noise immunity, as the device is not vulnerable to external noise sources. In addition, one power supply can be used to reduce power consumption. The device supports both AC and DC applications.

The SN74LVC244AZQNR device is used when two separate buses require bi-directional data exchange. It functions as a 3-state buffer for both buses. It is designed for AC and/or DC applications, and is designed to use both positive (VDD+) and negative (GND−) supplies. When operated from either the positive or negative supply, the SN74LVC244AZQNR provides high noise immunity and low power consumption.

The SN74LVC244AZQNR provides both input and output logical levels. On the inputs, it accepts a single-ended signal from either a 3V to 6V VDD- or a negative going signal of up to -1.5V GND−; the single-ended output levels range from 1.5V VDD+ to either 6V VDD− or -1.5V GND−. Because of its low quiescent current, this device is especially suitable for battery-powered systems.

The SN74LVC244AZQNR has two functions: buffering and line-driving. The octal buffer section provides 3-state outputs to minimize data contention, while the octal line-driver section provides outputs to transmit digital data over a longer distance. In addition, the line-driver section features bus-hold circuitry, which maintains output data when the device is powered off in the active state.

The SN74LVC244AZQNR is usually used for data transmission in AC and/or DC applications. It is a low voltage device that has been designed to operate with dual power supplies in order to reduce power consumption and provide high noise immunity. The device contains two operational blocks, a 3-state buffer section, and an octal line driver section. The buffer section provides 3-state outputs to reduce data contention while the line driver section provides prolonged data transmission over distance. Bus-hold circuitry is also included which maintains output data when the device is powered off. As a whole, the SN74LVC244AZQNR is an ideal solution for interfacing to FPGA or CPLD devices.
