changes output impedance,resulting in noise reduction
without speed degradation
• Low inductance multiple VCCand GND pins to minimize
noise and ground bounce
• Supports Live Insertion.
DESCRIPTION
The 74AVC16373 is a 16-bit D-type transparent latch
featuring separate D-type inputs for each latch, and
3-state outputs for bus oriented applications. One Latch
Enable (LE) input and one Output Enable (OE) input are
provided per 8-bit section. The 74AVC16373 consist of
two sections of eight D-type transparent latches with
3-state true outputs.
The 74AVC16373 is designed to have an extremely fast
propagation delay and a minimum amount of power
consumption.
To ensure the high-impedance output state during
power-up or power-down, pin OEn should be tied to V
through a pull-up resistor (Live Insertion).
A Dynamic Controlled Output (DCO) circuitry is
implemented to support termination line drive during
transient (see Figs 1 and 2).

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).
There is no soldering method that is ideal for all surface
mount IC packages.Wave soldering isnot always suitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.
Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
tothe printed-circuit boardbyscreen printing, stencilling or
pressure-syringe dispensing before package placement.
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.
Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.
Wave soldering
Conventional single wave soldering is not recommended
forsurfacemount devices (SMDs) orprinted-circuitboards
with a high component density, as solder bridging and
non-wetting can present major problems.
To overcome these problems the double-wave soldering
method was specifically developed.
If wave soldering is used the following conditions must be
observed for optimal results:
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint
– smaller than 1.27 mm, the footprint longitudinal axis
The footprint must incorporate solder thieves at the
downstream end.
• Forpackageswith leads on foursides,thefootprint 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.
During placement andbefore 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 dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Manual soldering
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.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.

longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;

printed-circuit board.

Limiting values
Limiting valuesgiven are in accordance with the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation
of the device at these or at any other conditions above those given in the Characteristics sections of the specification
is not implied. Exposure to limiting values for extended periods may affect device reliability.
