FEATURES  
DESCRIPTION  
5 V tolerant inputs/outputs for interfacing with 5 V logic  
Wide supply voltage range of 1.2 to 3.6 V  
Complies with JEDEC standard no. 8-1A  
CMOS low power consumption  
The 74LVC(H)32245A is a high-performance, low-power,  
low-voltage, Si-gate CMOS device, superior to most  
advanced CMOS compatible TTL families. Inputs can be  
driven from either 3.3 or 5 V devices. In 3-state operation,  
outputs can handle 5 V. These features allow the use of  
these devices in a mixed 3.3 and 5 V environment.  
MULTIBYTE flow-trough standard pin-out architecture  
Low inductance multiple power and ground pins for  
minimum noise and ground bounce  
The 74LVC(H)32245A is a 32-bit transceiver featuring  
non-inverting 3-state bus compatible outputs in both send  
and receive directions. The 74LVC(H)32245A features two  
output enable (nOE) inputs for easy cascading and two  
send or receive (nDIR) inputs for direction control. nOE  
controls the outputs so that the buses are effectively  
isolated.  
Direct interface with TTL levels  
Bus hold on data inputs (74LVCH32245A only)  
Typical output ground bounce voltage:  
VOLP < 0.8 V at VCC = 3.3 V; Tamb = 25 °C  
Typical output VOH undershoot voltage:  
To ensure the high-impedance state during power-up or  
power-down, input nOE should be tied to VCC through a  
pull-up resistor; the minimum value of the resistor is  
determined by the current-sinking capability of the driver.  
VOHV > 2 V at VCC = 3.3 V; Tamb = 25 °C  
Power-off disabled outputs, permitting live insertion  
Plastic fine-pitch ball grid array package.  
The 74LVCH32245A bus hold data inputs eliminates the  
need for external pull-up resistors to hold unused or  
floating data inputs at a valid logic level (see Fig.2).

Note  
1. CPD is used to determine the dynamic power dissipation (PD in µW).  
PD = CPD × VCC2 × fi + Σ(CL × VCC2 × fo) where:  
fi = input frequency in MHz;  
fo = output frequency in MHz;  
CL = output load capacitance in pF;  
VCC = supply voltage in Volts;  
Σ(CL × VCC2 × fo) = sum of the outputs.

3. Valid for data inputs of bus hold parts only (LVCH32xxx-A).  
4. For data inputs only. Control inputs do not have a bus hold circuit.  
5. The specified sustaining current at the data input holds the input below the specified VI level.  
6. The specified overdrive current at the data input forces the data input to the opposite logic input level.

SOLDERING  
If wave soldering is used the following conditions must be  
observed for optimal results:  
Introduction to soldering surface mount packages  
Use a double-wave soldering method comprising a  
turbulent wave with high upward pressure followed by a  
smooth laminar wave.  
This text gives a very brief insight to a complex technology.  
A more in-depth account of soldering ICs can be found in  
our “Data Handbook IC26; Integrated Circuit Packages”  
(document order number 9398 652 90011).  
For packages with leads on two sides and a pitch (e):  
– larger than or equal to 1.27 mm, the footprint  
longitudinal axis is preferred to be parallel to the  
transport direction of the printed-circuit board;  
There is no soldering method that is ideal for all surface  
mount IC packages. Wave soldering is not always suitable  
for surface mount ICs, or for printed-circuit boards with  
high population densities. In these situations reflow  
soldering is often used.  
– smaller than 1.27 mm, the footprint longitudinal axis  
must be parallel to the transport direction of the  
printed-circuit board.  
Reflow soldering  
The footprint must incorporate solder thieves at the  
downstream end.  
Reflow soldering requires solder paste (a suspension of  
fine solder particles, flux and binding agent) to be applied  
to the printed-circuit board by screen printing, stencilling or  
pressure-syringe dispensing before package placement.  
For packages with leads on four sides, the footprint must  
be placed at a 45° angle to the transport direction of the  
printed-circuit board. The footprint must incorporate  
solder thieves downstream and at the side corners.  
Several methods exist for reflowing; for example,  
infrared/convection heating in a conveyor type oven.  
Throughput times (preheating, soldering and cooling) vary  
between 100 and 200 seconds depending on heating  
method.  
During placement and before soldering, the package must  
be fixed with a droplet of adhesive. The adhesive can be  
applied by screen printing, pin transfer or syringe  
dispensing. The package can be soldered after the  
adhesive is cured.  
Typical reflow peak temperatures range from  
215 to 250 °C. The top-surface temperature of the  
packages should preferable be kept below 230 °C.  
Typical dwell time is 4 seconds at 250 °C.  
A mildly-activated flux will eliminate the need for removal  
of corrosive residues in most applications.  
Wave soldering  
Manual soldering  
Conventional single wave soldering is not recommended  
for surface mount devices (SMDs) or printed-circuit boards  
with a high component density, as solder bridging and  
non-wetting can present major problems.  
Fix the component by first soldering two  
diagonally-opposite end leads. Use a low voltage (24 V or  
less) soldering iron applied to the flat part of the lead.  
Contact time must be limited to 10 seconds at up to  
300 °C.  
To overcome these problems the double-wave soldering  
method was specifically developed.  
When using a dedicated tool, all other leads can be  
soldered in one operation within 2 to 5 seconds between  
270 and 320 °C.

Notes  
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum  
temperature (with respect to time) and body size of the package, there is a risk that internal or external package  
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the  
Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”.  
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink  
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).  
3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.  
The package footprint must incorporate solder thieves downstream and at the side corners.  
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;  
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.  
5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is  
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
