SN54HC240, SN74HC240 SCLS128G - DECEMBER 1982 - REVISED APRIL 2022 SNx4HC240 Octal Buffers and Line Drivers With 3-State Outputs 1 Features - Wide Operating Voltage Range of 2 V to 6 V - High-Current Outputs Drive Up To 15 LSTTL Loads - Low Power Consumption, 80-µA Max ICC - Typical tpd = 9 ns - ±6-m A Output Drive at 5 V - Low Input Current of 1 µA Max - 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers 2 Description 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 ’HC240 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.
