8-bit synchronous binary down counter
74HC/HCT40103
Counting is inhibited when the terminal enable input (TE)
is HIGH. The terminal count output (TC) goes LOW when
the count reaches zero if TE is LOW, and remains LOW for
one full clock period.
FEATURES
• Cascadable
• Synchronous or asynchronous preset
• Output capability: standard
When the synchronous preset enable input (PE) is LOW,
data at the jam input (P0 to P7) is clocked into the counter
on the next positive-going clock transition regardless of the
state of TE. When the asynchronous preset enable input
(PL) is LOW, data at the jam input (P0 to P7) is
asynchronously forced into the counter regardless of the
state of PE, TE, or CP. The jam inputs (P0 to P7) represent
a single 8-bit binary word.
• ICC category: MSI
GENERAL DESCRIPTION
The 74HC/HCT40103 are high-speed Si-gate CMOS
devices and are pin compatible with the “40103” of the
“4000B” series. They are specified in compliance with
JEDEC standard no. 7A.
When the master reset input (MR) is LOW, the counter is
asynchronously cleared to its maximum count (decimal
255) regardless of the state of any other input. The
precedence relationship between control inputs is
indicated in the function table.
The 74HC/HCT40103 consist each of an 8-bit
synchronous down counter with a single output which is
active when the internal count is zero. The “40103”
contains a single 8-bit binary counter and has control
inputs for enabling or disabling the clock (CP), for clearing
the counter to its maximum count, and for presetting the
counter either synchronously or asynchronously. All
control inputs and the terminal count output (TC) are
active-LOW logic.
If all control inputs except TE are HIGH at the time of zero
count, the counters will jump to the maximum count, giving
a counting sequence of 256 clock pulses long.
The “40103” may be cascaded using the TE input and the
TC output, in either a synchronous or ripple mode.
In normal operation, the counter is decremented by one
count on each positive-going transition of the clock (CP).

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
∑ (CL × VCC2 × fo) = sum of outputs
CL = output load capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC − 1.5 V

Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method.
SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
Typical reflow temperatures range from 215 to 250 °C.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
WAVE SOLDERING
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”
(order code 9398 652 90011).
Wave soldering can be used for all SO packages. Wave
soldering is not recommended for SSOP and TSSOP
packages, because of the likelihood of solder bridging due
to closely-spaced leads and the possibility of incomplete
solder penetration in multi-lead devices.
DIP
If wave soldering is used - and cannot be avoided for
SSOP and TSSOP packages - the following conditions
must be observed:
SOLDERING BY DIPPING OR BY WAVE
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
• The longitudinal axis of the package footprint must be
parallel to the solder flow and must incorporate solder
thieves at the downstream end.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (Tstg max). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
Even with these conditions:
• Only consider wave soldering SSOP packages that
have a body width of 4.4 mm, that is
SSOP16 (SOT369-1) or SSOP20 (SOT266-1).
• Do not consider wave soldering TSSOP packages
with 48 leads or more, that is TSSOP48 (SOT362-1)
and TSSOP56 (SOT364-1).
REPAIRING SOLDERED JOINTS
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
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.
SO, SSOP and TSSOP
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.
REFLOW SOLDERING
Reflow soldering techniques are suitable for all SO, SSOP
and TSSOP packages.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
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.

REPAIRING SOLDERED JOINTS
Fix the component by first soldering two diagonally- opposite end leads. Use only a low voltage soldering iron (less
than 24 V) 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.
