General Description

The LVT2245 and LVTH2245 contain eight non-inverting

bidirectional buffers with 3-STATE outputs and are

intended for bus-oriented applications. The Transmit/

Receive (T/R) input determines the direction of data flow

through the bidirectional transceiver. Transmit (active-

HIGH) enables data from A Ports to B Ports; Receive

(active-LOW) enables data from B Ports to A Ports. The

Output Enable input, when HIGH, disables both A and B

Ports by placing them in a high impedance state. The

equivalent 25 -series resistor in the B Port helps reduce

output overshoot and undershoot.

The LVTH2245 data inputs include bushold, eliminating

the need for external pull-up resistors to hold unused

inputs.

These transceivers are designed for low voltage (3.3V)

interface to a 5V environment. The LVT2245 and

LVTH2245 are fabricated with an advanced BiCMOS

technology to achieve high speed operation similar to 5V

ABT while maintaining low power dissipation.
