1 / 14 page SN54HCT240, SN74HCT240 OCTAL BUFFERS AND LINE DRIVERS WITH 3STATE OUTPUTS SCLS174E − MARCH 1984 − REVISED AUGUST 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Operating Voltage Range of 4.5 V to 5.5 V D High-Current Outputs Drive Up To 15 LSTTL Loads D Low Power Consumption, 80-µA Max ICC D Typical tpd = 12 ns D ±6-mA Output Drive at 5 V D Low Input Current of 1 µA Max D Inputs Are TTL-Voltage Compatible D 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers description/ordering information These 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 ’HCT240 devices are organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes inverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
