3.3 V 32-bit bus transceiver with 30 termination resistors;  
3-state  
Rev. 01 — 24 January 2007  
Product data sheet  
1. General description  
The 74LVTH322245 is a high-performance BiCMOS product designed for VCC operation  
at 3.3 V. The 74LVTH322245 is designed with 30 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  
I 32-bit bidirectional bus interface  
I 3-state buffers  
I Output capability: +12 mA and 12 mA  
I TTL input and output switching levels  
I Input and output interface capability to systems at 5 V supply  
I Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs  
I Live insertion and extraction permitted  
I Outputs include series resistance of 30 making external resistors unnecessary  
I Power-up 3-state  
I No bus current loading when output is tied to 5 V bus  
I Latch-up protection:  
N JESD78 Class II level A exceeds 500 mA  
I ESD protection:  
N HBM JESD22-A114E exceeds 2000 V  
N MM JESD22-A115-A exceeds 200 V

[1] Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the  
device at these or any other conditions beyond indicated under Section 8 “Recommended operating conditions” is not implied. Exposure  
to absolute-maximum-rated conditions for extended periods may affect device reliability.  
[2] The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction  
temperatures which are detrimental to reliability.  
[3] The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.

[3] This is the bus-hold overdrive current required to force the input to the opposite logic state.  
[4] This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.3 V ± 0.3 V  
a transition time of 100 µs is permitted. This parameter is valid for Tamb = 25 °C only.

specified use without further testing or modification.  
Limiting values — Stress above one or more limiting values (as defined in  
the Absolute Maximum Ratings System of IEC 60134) may cause permanent  
damage to the device. Limiting values are stress ratings only and operation of  
the device at these or any other conditions above those given in the  
Characteristics sections of this document is not implied. Exposure to limiting  
values for extended periods may affect device reliability.  
Short data sheet — A short data sheet is an extract from a full data sheet  
with the same product type number(s) and title. A short data sheet is intended  
for quick reference only and should not be relied upon to contain detailed and  
full information. For detailed and full information see the relevant full data  
sheet, which is available on request via the local NXP Semiconductors sales  
office. In case of any inconsistency or conflict with the short data sheet, the  
full data sheet shall prevail.  
Terms and conditions of sale — NXP Semiconductors products are sold  
subject to the general terms and conditions of commercial sale, as published  
at http://www.nxp.com/profile/terms, including those pertaining to warranty,  
intellectual property rights infringement and limitation of liability, unless  
explicitly otherwise agreed to in writing by NXP Semiconductors. In case of
