Product data sheet

1. General description

The 74LVTH322245 is a high-performance BiCMOS product designed for V

operation

at 3.3 V. The 74LVTH322245 is designed with 30

Ω

series resistance in both the HIGH

and LOW states of the output. This design reduces line noise in applications such as

memory address drivers, clock drivers, and bus receivers/transmitters. The

74LVTH322245 is a 32-bit transceiver featuring non-inverting 3-state bus compatible

outputs in both send and receive directions. The device features four output enable (nOE)

inputs for easy cascading and four send/receive (nDIR) inputs for direction control.

Pin nOE controls the outputs so that the buses are effectively isolated. Bus hold on data

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

2. Features

32-bit bidirectional bus interface

3-state buffers

Output capability: +12 mA and

−12

TTL input and output switching levels

Input and output interface capability to systems at 5 V supply

Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs

Live insertion and extraction permitted

Outputs include series resistance of 30

Ω

making external resistors unnecessary

Power-up 3-state

No bus current loading when output is tied to 5 V bus

Latch-up protection:

JESD78 Class II level A exceeds 500 mA

ESD protection:

HBM JESD22-A114E exceeds 2000 V

MM JESD22-A115-A exceeds 200 V
