产品概述

The SN74LVC245APW is an octal Bus Transceiver with 3-state outputs and designed for 1.65 to 3.6V VCC operation. This device is designed for asynchronous communication between data buses. This device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control input. The output-enable input can be used to disable the device so the buses effectively are isolated. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver. Inputs can be driven from either 3.3/5V devices. This feature allows the use of this device as a translator 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 device when it is powered down.
  • IOFF Supports live insertion, partial-power-down mode and back-drive protection
  • Allows down voltage translation
  • Supports mixed-mode signal operation on all ports
  • Inputs accept voltages to 5.5V
  • Latch-up performance exceeds 250mA per JESD 17
  • 6.3ns 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
