SN54HC244 Datasheet | Texas Instruments

Features - Wide Operating Voltage Range of 2 V to 6 V - High-Current Outputs Drive Up to 15 LSTTL Loads - 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers - Low Power Consumption: ICC, 80-µA (Maximum) - Typical tpd = 11 ns - ±6-m A Output Drive at 5 V - Low Input Current of 1 µA (Maximum) - On Products pliant to MIL-PRF-38535, All Parameters Are Tested Unless Otherwise Noted. On All Other Products, Production Processing Does Not Necessarily Include Testing of All Parameters. 2 Applications - Servers - LED Displays - Network Switches - Tele Infrastructure - Motor Drivers - I/O Expanders 3 Description The SNx4HC244 octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The SNx4HC244 devices are organized as two 4bit buffers and 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 highimpedance state.
