74ALVC245 Low Voltage Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs
General Description
The ALVC245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The T/R input determines the direction of data flow. The OE input disables both the A and B ports by placing them in a high impedance state. The 74ALVC245 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74ALVC245 is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low CMOS power dissipation.

Note 1: To ensure the high impedance state during power up and power down, OEn should be tied to VCC through a pull up resistor. The minimum value of the resistor is determined by the current sourcing capability of the driver.
