74ALVC244

The SN74ALVC244 is an octal buffer/line driver manufactured by NXP Semiconductors, designed for versatile operation within a 1.65-V to 3.6-V supply voltage range. This device is organized as two independent 4-bit line drivers, each controlled by a separate output-enable (OE) input. When the OE input is low, data is passed from the A inputs to the Y outputs. When OE is high, the outputs enter a high-impedance state, which is crucial for power-up and power-down sequences when OE is tied to VCC through a pull-up resistor.

Key electrical characteristics include a maximum propagation delay of 2.8 ns at 3.3 V and a significant output drive capability of ±24 mA at 3.3 V. The device operates over a temperature range of -40°C to 85°C. It also boasts over-voltage tolerant inputs and balanced outputs, contributing to its high-speed performance.

For robust system integration, the SN74ALVC244 provides excellent ESD protection, exceeding JESD 22 standards with 2000-V for the Human-Body Model, 200-V for the Machine Model, and 1000-V for the Charged-Device Model. Its latch-up performance exceeds 250 mA per JESD 17, ensuring reliability in demanding applications. The component is available in various package types, including TSSOP, VQFN, SOIC, TVSOP, and SOP.

This buffer/line driver is suitable for applications requiring high-speed signal buffering and level shifting within the specified voltage range. Its 3-state capability makes it ideal for bus-oriented systems and applications where output control is necessary.
