74LVT32245 • 74LVTH32245

Low Voltage 32-Bit Transceiver with 3-STATE Outputs

General Description

The LVT32245 and LVTH32245 contain thirty-two non-

inverting bidirectional buffers with 3-STATE outputs and are

intended for bus oriented applications. The devices are

byte controlled. Each byte has separate control inputs

which can be shorted together for full 32-bit operation. The

T/R inputs 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 LVTH32245 data inputs include bushold, eliminating

the need for external pull-up resistors to hold unused

inputs.

These non-inverting transceivers are designed for low volt-

vide a TTL interface to a 5V environment. The LVT32245

and LVTH32245 are fabricated with an advanced BiCMOS

technology to achieve high speed operation similar to 5V

ABT while maintaining low power dissipation.
