Product Overview

The SN74LVC540ADW is an octal Buffer/Driver with 3-state outputs and designed for 1.65 to 3.6V VCC operation. This device is ideal for driving bus lines or buffer memory address registers. It features inputs and outputs that 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 input is high, all outputs are in the high-impedance state. Inputs can be driven from either 3.3/5V devices. This feature allows the use of these devices as translators in a mixed 3.3/5V system environment. This device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.
  • IOFF Supports live insertion, partial-power-down mode and back drive protection
  • Latch-up performance exceeds 250mA per JESD 78, class II
  • Allows down voltage translation
  • Inputs accept voltages to 5.5V
  • 5.3ns at 3.3V Propagation delay (tpd)
  • <0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)
  • >2V at VCC = 3.3V, TA = 25°C VOHV (output VOH undershoot)
  • Green product and no Sb/Br
