Dual JK flip-flop with set and reset;
negative-edge trigger
74HC/HCT112
The set and reset inputs, when LOW, set or reset the
outputs as shown in the function table regardless of the
levels at the other inputs.
FEATURES
• Asynchronous set and reset
• Output capability: standard
• ICC category: flip-flops
A HIGH level at the clock (nCP) input enables the nJ and
nK inputs and data will be accepted. The nJ and nK inputs
control the state changes of the flip-flops as shown in the
function table. The nJ and nK inputs must be stable one
set-up time prior to the HIGH-to-LOW clock transition for
predictable operation.
GENERAL DESCRIPTION
The 74HC/HCT112 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.
Output state changes are initiated by the HIGH-to-LOW
transition of nCP.
Schmitt-trigger action in the clock input makes the circuit
highly tolerant to slower clock rise and fall times.
The 74HC/HCT112 are dual negative-edge triggered
JK-type flip-flops featuring individual nJ, nK, clock (nCP),
set (nSD) and reset (nRD) inputs.

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

SOLDERING
Introduction
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.
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 “Data Handbook IC26; Integrated Circuit Packages”
(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
SOLDERING BY DIPPING OR BY WAVE
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
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.
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.
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
SO, SSOP and TSSOP
6 seconds. Typical dwell time is 4 seconds at 250 °C.
REFLOW SOLDERING
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Reflow soldering techniques are suitable for all SO, SSOP
and TSSOP packages.
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
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
