SN74HC244N

The SN74HC244N is an Octal Buffer and Line Driver IC, designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers and bus-oriented receivers and transmitters. This device organized as two 4-bit buffers/drivers with separate output-enable (OE)/inputs. When OE/ is low, the device passes non-inverted data from the A inputs to the Y outputs. When OE/ is high, the outputs are in the high-impedance state.

• High-current Outputs Drive up to 15 LSTTL Loads
• 3-state Outputs Drive Bus Lines or Buffer Memory Address Registers
• Low-power Consumption, 80μA Maximum ICC
• 11ns Typical Propagation Delay Time
• ±6mA Output Drive at 5V
• 1µA (maximum) Low Input Current

警告

Input and output voltage ratings may be exceeded if the input and output current ratings are observed, package thermal impedance is calculated in accordance with JESD 51-7.
