DESCRIPTION/ORDERING INFORMATION  
This 8-bit (octal) noninverting bus transceiver contains two separate supply rails. The B port is designed to track  
VCCB, which accepts voltages from 3 V to 5.5 V, and the A port is designed to track VCCA, which operates at 2.3  
V to 3.6 V. This allows for translation from a 3.3-V to a 5-V system environment and vice versa, from a 2.5-V to a  
3.3-V system environment and vice versa.  
The SN74LVCC3245A is designed for asynchronous communication between data buses. The device transmits  
data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the  
direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are  
effectively isolated. The control circuitry (DIR, OE) is powered by VCCA  
.

Power-Up Considerations  
TI level-translation devices offer an opportunity for successful mixed-voltage signal design. A proper power-up  
sequence always should be followed to avoid excessive supply current, bus contention, oscillations, or other  
anomalies caused by improperly biased device pins. To guard against such power-up problems, take these  
precautions:  
1. Connect ground before any supply voltage is applied.  
2. Power up the control side of the device (VCCA for all four of these devices).  
3. Tie OE to VCCA with a pullup resistor so that it ramps with VCCA  
.
4. Depending on the direction of the data path, DIR can be high or low. If DIR high is needed (A data to B bus),  
ramp it with VCCA. Otherwise, keep DIR low.  
(1) Refer to the TI application report, Texas Instruments Voltage-Level-Translation Devices, literature number SCEA021.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in  
a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2)  
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and  
Addendum-Page 1  
PACKAGE OPTION ADDENDUM  
www.ti.com

package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS  
compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)  
(3)  
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder  
temperature.
