74LVC540A
OCTAL BUFFER/ LINE DRIVER WITH 3 STATE OUTPUTS
Description
Pin Assignments
The 74LVC540A is an octal inverting buffer/driver is designed for
driving bus lines or buffer memory address registers. The 3-state
control gate is a 2-input AND gate with active-low inputs so that, if
either output enable (OE1 or OE2) input is high, all eight outputs are in
the high-impedance state..These devices feature inputs and outputs
on opposite sides of the package that facilitate printed circuit board
layout.
The device is designed for operation with a power supply range of
1.65V to 3.6V.
The inputs are tolerant to 5.5V allowing this device to be used in a
mixed voltage environment. The device is fully specified for partial
power down applications using IOFF. The IOFF circuitry disables the
output preventing damaging current backflow when the device is
powered down.

Notes:
6. Stresses beyond the absolute maximum may result in immediate failure or reduced reliability. These are stress values and device operation should be
within recommend values.
7. Forcing the maximum allowed voltage could cause a condition exceeding the maximum current or conversely forcing the maximum current could
cause a condition exceeding the maximum voltage. The ratings of both current and voltage must be maintained within the controlled range.
