Low Voltage Octal Bidirectional Transceiver

with 3-STATE Inputs/Outputs

General Description

Features

■ Input and output interface capability to systems at

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.

5V V_CC

■ Bushold data inputs eliminate the need for external

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

also available without bushold feature (74LVT245)

■ Live insertion/extraction permitted

■ Power Up/Down high impedance provides glitch-free

bus loading

■ Outputs source/sink, 32 mA/ 64 mA

■ Latch-up performance exceeds 500 mA

■ ESD performance:

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)

V_CCapplications, 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.
