description
The SN54LVC541A octal buffer/driver is designed
for 2.7-V to 3.6-V V
CC
operation and the
SN74LVC541A octal buffer/driver is designed for
1.65-V to 3.6-V V
CC
operation.
The ’LVC541A devices are ideal for driving bus
lines or buffering memory address registers.

These devices feature inputs and outputs on opposite sides of the package to facilitate printed circuit board
layout.
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.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators
in a mixed 3.3-V/5-V system environment.
The SN54LVC541A is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74LVC541A is characterized for operation from –40°C to 85°C.
