The 74LVCR162245APVG8 is a low-voltage, high-performance octal buffer and line driver with 3-STATE outputs and uses advanced CMOS,Hi-Speed differential line driver and line receiver technologies. This device is optimized for driving heavily-loaded buses and has the capability to drive up to 30 V over a -7V to 12V common-mode voltage range on outputs with series 51Ωresistor. The device is designed to meet or exceed industry standards for RS-422 and EIA/TIA -485 applications and are ideal for applications with distributed terminated transmission line lengths or capacitive loaded bus lines.

Application Field

The 74LVCR162245APVG8 is a low voltage, octal buffer and line driver with 3-STATE outputs. It is commonly used in a variety of applications such as networking and bus switching, high-speed communications, embedded processing, and high-speed point-to-point interconnects. This device is optimized for driving heavily-loaded buses and can drive up to 30V over a -7V to 12V common-mode voltage range on outputs with series 51Ω resistor. This buffer and line driver is ideal for multiplexers, bus switches, serial communication lineup, bus transceivers, memory decoders, and clocks.

Working Principle

The 74LVCR162245APVG8 is designed to operate as a non-inverting buffer/driver that transmits data from the A port to the B port. An occurrence on the local port drives the corresponding output of its B port, creating a low-impedance pulse. The 3-STATE feature allows the B port to be disabled independent of the local port. This flexibility makes it easy to separate data paths from the drivers. The device also features a high-speed differential line driver which provides improved signal integrity in applications with long-trace transmission lines. The line driver is designed to provide excellent voltage levels and controlled rise and fall times. The output characteristics are designed to meet or exceed industry standards for RS-422 and EIA/TIA-485 applications.

The device also features a high-speed differential line receiver that is ideal for terminals, multiplexers and clock circuits. The line receiver is capable of accurately driving the outputs to their high voltage state when the inputs are at their low voltage state. The output of the line receiver is also capable of exhibiting the same high-to-low propagation delay as the line drivers, allowing for extremely low skew between the input and output signals.

The 74LVCR162245APVG8 can be used for many different applications ranging from multiplexers and bus switches to serial communications to embedded processing. This device is capable of providing high-speed, high-performance operations with low-power consumption and enables a wide range of design options.
