Note 3: Absolute Maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute maximum rated conditions is not implied. Note 4: I_O Absolute Maximum Rating must be observed.

The 74LVT322245 contain thirty-two noninverting bidirectional buffers with 3-STATE outputs and are intended for bus oriented applications. The device is byte controlled. Each byte has separate control inputs which can be shorted together for full 32-bit operation. The T/Rinputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state.

The 74LVT322245 are designed with equivalent 25 series resistance in both the HIGH and LOW states on the A Port outputs. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters.

The 74LVT322245 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.

These non-inverting transceivers are designed for low-voltage (3.3V) V_CC applications, but with the capability to provide a TTL interface to a 5V environment. The 74LVT322245 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.
