FEATURES * Wide supply voltage range from 2.0 to 6.0 V * High noise immunity * Low power dissipation * Balanced propagation delays * Unlimited input rise and fall times * Very small 6 pins package. APPLICATIONS * Wave and pulse shapers for highly noisy environments * Astable multivibrators QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C; tr = tf 6.0 ns. DESCRIPTION
74HC2G14; 74HCT2G14
* Monostable multivibrators * Output capability: standard.
The 74HC2G/HCT2G14 is a high-speed Si-gate CMOS device. The 74HC2G/HCT2G14 provides two inverting buffers with Schmitt-trigger action. This device is capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.
TYPICAL SYMBOL tPHL/tPLH CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total switching outputs; (CL x VCC2 x fo) = sum of outputs. 2. For HC2G the condition is VI = GND to VCC. For HCT2G the condition is VI = GND to VCC - 1.5 V. FUNCTION TABLE See note 1. INPUTS nA L H Note 1. H = HIGH voltage level; L = LOW voltage level.

APPLICATION INFORMATION The slow input rise and fall times cause additional power dissipation, this can be calculated using the following formula: Pad = fi x (tr x ICCa + tf x ICCa) x VCC Where: Pad = additional power dissipation (W) fi = input frequency (MHz) tr = input rise time (ns); 10% to 90% tf = input fall time (ns); 90% to 10% ICCa = average additional supply current (A).

SOLDERING Introduction to soldering surface mount packages 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" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. Reflow soldering 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. Several methods exist for reflowing; for example, convection or convection/infrared 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 220 C for thick/large packages, and below 235 C for small/thin packages. Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards 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.
74HC2G14; 74HCT2G14
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 longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint 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 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. 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.

Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE WAVE BGA, HBGA, LFBGA, SQFP, TFBGA HBCC, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, HVQFN, SMS PLCC(3), SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO Notes 1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. not suitable not not not suitable(2) recommended(3)(4) recommended(5) suitable REFLOW(1) suitable suitable suitable suitable suitable
