74LVT2245 • 74LVTH2245

Low Voltage Octal Bidirectional Transceiver with

3-STATE Inputs/Outputs and 25: Series Resistors

in the B Port Outputs

General Description

Features

■ Input and output interface capability to systems at

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.

5V V_CC

■ Equivalent 25 series resistor on B Port outputs

■ Bushold data inputs eliminate the need for external

pull-up resistors to hold unused inputs (74LVTH2245),

also available without bushold feature (74LVT2245)

■ Live insertion/extraction permitted

■ Power Up/Down high impedance provides glitch-free

bus loading

■ Outputs source/sink 12 mA/ 12 mA on B Port,

The LVTH2245 data inputs include bushold, eliminating the

need for external pull-up resistors to hold unused inputs.

32 mA/ 64 mA on A Port

■ Latch-up performance exceeds 500 mA

■ ESD performance:

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 LVT2245 and

LVTH2245 are fabricated with an advanced BiCMOS tech-

nology to achieve high speed operation similar to 5V ABT

while maintaining low power dissipation.
