The 74LVC540A is an octal buffer/line driver with 3-state outputs, which can accept supply voltage range from 1.65V to 3.6V. The device is the best choice for driving bus lines or buffer memory address registers. The inputs and outputs are placed on opposite sides of the package, making it easier to print circuit board layout.
The device features 3-state control gate consisting of a two-input AND gate with active-low inputs. OE1 and OE2 are two output enable inputs. When OE1 or OE2 is high, all outputs are in high-impedance state. Both 3.3V and 5V devices can drive inputs, enabling this device to operate as translator in a mixed 3.3V and 5V system environment.
This device is highly suitable for partial power-down applications by using power-off leakage current (IOFF) circuit. When the device is powered down, the outputs are disabled, and the current backflow can be prevented from passing through the device.
The 74LVC540A is available in a Green TSSOP-20 package. It operates over an operating temperature range of -40℃ to +125℃.
