PI90LV048AL is a low-voltage, octal non-inverting buffer/line driver that is designed to operate from a broad voltage range, including TTL levels and static CMOS levels. It is suitable for both memory and logic applications and is optimized for high-speed operations. The device is available in a 3-state configuration and leverages TI’s patented low voltage design for faster switching and much longer data retention times. This paper gives an overview of the application field and working principle of PI90LV048AL.

Application Field of PI90LV048AL

The PI90LV048AL is a versatile device which can be used in many applications. It is a perfect choice in all low-voltage/low-power electronic applications due to its wide voltage range and low current operation. Some of the applications are listed below:

• It can be used to drive multiple data buses in low-voltage systems. It can be used in microprocessor-based systems such as PCs, notebooks, and tablets.
• It can be used in memory boards, memory cards, and flash memory.
• It can be used in digital signal processor (DSP) and digital circuits.
• It can be used in High-speed communications such as USB and Ethernet.

Working Principle of PI90LV048AL

The PI90LV048AL operates in three main modes: active, 3-state, and latch-off. In active mode, the input signal is applied to the input terminal and output signals are generated at the output terminals. These output signals can be used for driving the associated loads. In 3-state mode the PI90LV048AL is forced into the three-state mode, where no outputs are generated. This mode is used when the device is not actively used in the circuit. The latch-off mode is used to turn off the device. This involves setting all the outputs to the high-impedance state. In this mode, the PI90LV048AL consumes almost no static current.

The PI90LV048AL is designed to operate at low voltage levels and it implements a patented low voltage design. This design technology allows the device to switch quickly and latch the data reliably. The buffer uses CMOS technology to achieve low-voltage operation. The sensing threshold voltage of the device is at 1.25V and it can operate from a voltage range of 0.6V to 5V. This flexibility to operate over a wide voltage range makes the device suitable for various applications.

The PI90LV048AL integrates an output inverter at every output line, which ensures that the signal can be inverted at the output to match the logic levels of the receiving device. The device also includes Active Pull-Ups, which ensure that the output signal is held at a stable high level when the device is in 3-state mode. On-chip ESD protection ensures that the device is immune to ESD transients up to 2KV.

The PI90LV048AL is designed to use low power, and therefore it consumes very low current in all its operating modes. Also, due to the low-voltage design, the device has a wide input threshold range, so it can work reliably with inputs that have a pulse width as low as 1ns. This makes the device suitable for high-speed applications.

Overall, the PI90LV048AL is a versatile device which can be used in various low-voltage, low-power electronic applications such as memory, logic, and high-speed communications. Its patented low-voltage design and wide voltage range make it a perfect choice for applications requiring fast switching and reliable data retention time.
