pull-up resistors to hold unused inputs (74LVTH245),

also available without bushold feature (74LVT245)

bus loading

– Charged-device model > 1000V

General Description

The LVT245 and LVTH245 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 Z condition.

The LVTH245 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 LVT245 and

LVTH245 are fabricated with an advanced BiCMOS

technology to achieve high speed operation similar to 5V

ABT while maintaining a low power dissipation.
