This octal buffer/line driver is designed for 1.65-V to 3.6-V VCC operation. The 74LVC2244A is organized as two 4-bit 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. The outputs, which are designed to sink up to 12 mA, include equivalent 26-W resistors to reduce overshoot and undershoot.
Operates From 1.65 V to 3.6 V
Inputs Accept Voltages to 5.5 V
Max tpd of 5.5 ns at 3.3 V
Output Ports Have Equivalent 26-W Series Resistors, So No External Resistors Are Required
Typical VOLP (Output Ground Bounce) <0.8 V at VCC = 3.3 V, TA = 25°C
Typical VOHV (Output VOH Undershoot) >2 V at VCC = 3.3 V, TA = 25°C
Supports Mixed-Mode Signal Operation on All Ports (5-V Input/Output Voltage with 3.3-V VCC)
Ioff Supports Partial-Power-Down Mode Operation
