description
These octal buffers/drivers are designed for 2-V to
5.5-V VCC operation.
The ’LV240A devices are designed specifically to
improve both the performance and density of
3-state memory address drivers, clock drivers,
and bus-oriented receivers and transmitters.
These devices are organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs. When
OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the
high-impedance state.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54LV240A is characterized for operation over the full military temperature range of –55
°C to 125°C. The
SN74LV240A is characterized for operation from –40
°C to 85°C.
