Product Summary
The SN74HC244DWR is a octal buffer and line driver. The SN74HC244DWR is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The SN74HC244DWR is organized as two 4-bit buffers/drivers with separate output-enable(OE) inputs. When OE is low, the device passes noninverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
Parametrics
SN74HC244DWR absolute maximum ratings: (1)Supply voltage range:–0.5 V to 7 V; (2)Input clamp current, IIK (VI < 0 or VI > VCC):±20 mA; (3)Output clamp current, IOK (VO < 0 or VO > VCC):±20 mA; (4)Continuous output current, IO (VO = 0 to VCC):±35 mA; (5)Continuous current through VCC or GND:±70 mA; (6)Package thermal impedance, θJA (see Note 2):58℃/W; (7)Storage temperature range:–65℃ to 150℃.
