The ’LV368A devices are hex buffers and line
drivers designed for 2-V to 5.5-V V operation.
These 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.

The ’LV368A devices are organized as dual 4-line
and 2-line buffers/drivers with active-low
output-enable (1OE and 2OE) 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.
NC – No internal connection
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the
driver.
The SN54LV368A is characterized for operation over the full military temperature range of –55°C to 125°C. The
SN74LV368A is characterized for operation from –40°C to 85°C.
