Overview
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-mA 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.
