74LVC245A - OCTAL BUS TRANSCEIVER

General Description

The 74LVC245A is an octal transceiver designed for asynchronous communication between data buses.

The 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 (DIR) input.

Key Features

  • Supply Voltage Range from 1.65V to 3.6V.
  • Sinks or Sources 24ma at VCC = 3V.
  • CMOS Low Power Consumption.
  • IOFF Supports Partial Power Down Operation.
  • Inputs or Outputs Accept Up to 5.5V.
  • Inputs Can Be Driven by 3.3V or 5V Allowing for Mixed Voltage.

NEW PRODUCT 74LVC245A OCTAL BUS TRANSCEIVER WITH 3 STATE OUTPUTS Description The 74LVC245A is an octal transceiver designed for asynchronous communication between data buses. The 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 (DIR) input. The output-enable (OE) pin can be used to disable the device so the buses effectively are isolated. 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 IOFF. The IOFF circuitry disables the output preventing damaging current backflow when the device is powered down.
