SN74LV244APWR .

The SN74LV244APWR is an octal Buffer/Line Driver with 3-state outputs and is designed for 2 to 5.5V VCC operation. This device is designed specifically to improve both performance and density of the 3-state memory address drivers, clock drivers and bus-oriented receivers and transmitters. This device is organized as two 4-bit line drivers with separate output-enable (OE) inputs. The octal buffer grouped fours, with each group having its own enable pin. The LV family supports high current drive of about 16mA, thus making it suitable for driving digital signals over longer board lengths. This device is generally used to buffer or incorporate delays between the signals between two microcontroller and peripheral devices.

• Support mixed-mode voltage operation on all ports
• IOFF Supports partial-power-down mode operation
• Latch-up performance exceeds 250mA per JESD 17
• 6.5ns at 5V Propagation delay (tpd)
• <0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)
• >2.3V at VCC = 3.3V, TA = 25°C VOHV (output VOH undershoot)
• Green product and no Sb/Br
