74LVT32245 • 74LVTH32245

Low Voltage 32-Bit Transceiver with 3-STATE Outputs

General Description

Features

The LVT32245 and LVTH32245 contain thirty-two non-

inverting bidirectional buffers with 3-STATE outputs and are

intended for bus oriented applications. The devices are

byte controlled. Each byte has separate control inputs

which can be shorted together for full 32-bit operation. The

T/R inputs determine the direction of data flow through the

device. The OE inputs disable both the A and B ports by

placing them in a high impedance state.

■ Input and output interface capability to systems at

5V V_CC

■ Bushold data inputs eliminate the need for external

pull-up resistors to hold unused inputs (74LVTH32245),

also available without bushold feature (74LVT32245).

■ Live insertion/extraction permitted

■ Power Up/Down high impedance provides glitch-free

bus loading

The LVTH32245 data inputs include bushold, eliminating

the need for external pull-up resistors to hold unused

inputs.

■ Outputs source/sink −32 mA/+64 mA

■ ESD performance:

These non-inverting transceivers are designed for low volt-

age (3.3V) V_CCapplications, but with the capability to pro-

Human-body model > 2000V

Machine model > 200V

vide a TTL interface to a 5V environment. The LVT32245

and LVTH32245 are fabricated with an advanced BiCMOS

technology to achieve high speed operation similar to 5V

ABT while maintaining low power dissipation.

Charged-device model > 1000V

■ Packaged in plastic Fine-Pitch Ball Grid Array (FBGA)
