FEATURES * Asynchronous set and reset * Output capability: standard 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. Output state changes are initiated by the HIGH-to-LOW transition of nCP. * ICC category: flip-flops 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. 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.

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. REFLOW SOLDERING 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 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. SO, SSOP and TSSOP 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 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 Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary 1998 Jun 10 14 Philips Semiconductors Product specification Dual JK flip-flop with set and reset; negative-edge trigger 74HC/HCT112 one operation within 2 to 5 seconds between 270 and 320 C.
