74LVT245
74LVTH245
Low Voltage Octal Bidirectional Transceiver
with 3-STATE Inputs/Outputs
General Description
The LVT245 and LVTH245 contain eight non-inverting bidi-
rectional 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 bidi-
rectional 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)

applications, but with the capability to provide a TTL
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.
