(SD) and reset (RD) inputs; also complementary Q and Q
outputs.
FEATURES
• J, K inputs for easy D-type flip-flop
The set and reset are asynchronous active LOW inputs
and operate independently of the clock input.
• Toggle flip-flop or “do nothing” mode
• Output capability: standard
The J and K inputs control the state changes of the
flip-flops as described in the mode select function table.
• ICC category: flip-flops
The J and K inputs must be stable one set-up time prior to
the LOW-to-HIGH clock transition for predictable
operation.
GENERAL DESCRIPTION
The 74HC/HCT109 are high-speed Si-gate CMOS devices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.
The JK design allows operation as a D-type flip-flop by
tying the J and K inputs together.
Schmitt-trigger action in the clock input makes the circuit
highly tolerant to slower clock rise and fall times.
The 74HC/HCT109 are dual positive-edge triggered, JK
flip-flops with individual J, K inputs, clock (CP) inputs, set

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.

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.
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.
WAVE SOLDERING
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.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “IC Package Databook” (order code 9398 652 90011).
If wave soldering is used - and cannot be avoided for
SSOP and TSSOP packages - the following conditions
must be observed:
DIP
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
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.
• The longitudinal axis of the package footprint must be
parallel to the solder flow and must incorporate solder
thieves at the downstream end.
Even with these conditions:
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.
• Only consider wave soldering SSOP packages that
have a body width of 4.4 mm, that is
SSOP16 (SOT369-1) or SSOP20 (SOT266-1).
REPAIRING SOLDERED JOINTS
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.
• Do not consider wave soldering TSSOP packages
with 48 leads or more, that is TSSOP48 (SOT362-1)
and TSSOP56 (SOT364-1).
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.
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.
SO, SSOP and TSSOP
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
REFLOW SOLDERING
Reflow soldering techniques are suitable for all SO, SSOP
and TSSOP packages.
REPAIRING SOLDERED JOINTS
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.
Fix the component by first soldering two diagonallyopposite 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.
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method.
