SN74LVC244ADBR

The SN74LVC244ADBR is an octal Buffer/Driver with 3-state outputs and designed for 1.65 to 3.6V VCC operation. This device is also designed for asynchronous communication between data buses. This device is organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.

• IOFF Supports live insertion, partial-power-down mode and back-drive protection
• Allows down voltage translation
• Supports mixed-mode signal operation on all ports
• Inputs accept voltages to 5.5V
• Latch-up performance exceeds 250mA per JESD 17
• 5.9ns at 3.3V Propagation delay (tpd)
• <lt/>0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)
• <gt/>2V at VCC = 3.3V, TA = 25°C VOHV (output VOH undershoot)
• Green product and no Sb/Br
