SN74LVTH244ADWR

The Texas Instruments SN74LVTH244ADWR is an octal buffer and line driver designed for 3.3V VCC operation, offering compatibility with 5V systems. This device features two 4-bit drivers with separate output-enable (OE) inputs. When OE is low, data passes from the A inputs to the Y outputs; when OE is high, the outputs are in a high-impedance state.

Key electrical characteristics include a wide operating voltage range of 2.7V to 3.6V, with support for mixed-mode signal operation allowing 5V input and output voltages with a 3.3V VCC. It provides 3-state outputs and features bus-hold on data inputs, eliminating the need for external pull-up or pull-down resistors. The device also supports hot insertion and unregulated battery operation down to 2.7V.

This buffer is supplied in a 20-SOIC surface mount package. It has a typical output ground bounce of less than 0.8V at 3.3V VCC and 25°C. Latch-up performance exceeds 500 mA per JESD 17, and ESD protection meets JESD 22 standards (2000V HBM, 200V MM).

Applications for the SN74LVTH244ADWR include general-purpose buffering, signal translation between different voltage domains, and bus interfacing where 3-state capability is required.
