74LVC541A
OCTAL BUFFER/ LINE DRIVER WITH 3 STATE OUTPUTS
Description
The 74LVC541A is an octal 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 I
OFF
. The I
OFF
circuitry disables the
output preventing damaging current backflow when the device is
powered down.
