DESCRIPTION The 74AHC1G/AHCT1G66 is a high-speed Si-gate CMOS device. The 74AHC1G/AHCT1G66 provides an analog switch. The switch has two input/output pins (Y and Z) and an active HIGH enable input pin (E). When pin E is LOW, the analog switch is turned off.
TYPICAL SYMBOL tPZH/tPZL tPHZ/tPLZ CI CPD CS Notes 1. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi + ((CL + CS) x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; CS = maximum switch capacitance in pF; VCC = supply voltage in Volts. 2. The condition is VI = GND to VCC.

To avoid drawing VCC current out of pin Z, when switch current flows into pin Y, the voltage drop across the bidirectional switch must not exceed 0.4 V. If the switch current flows into pin Z, no VCC current will flow out of pin Y. In this case there is no limit for the voltage drop across the switch, but the voltage at pins Y and Z may not exceed VCC or GND.

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.
74AHC1G66; 74AHCT1G66
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 PACKAGE(1) BGA, LBGA, LFBGA, SQFP, TFBGA, VFBGA HBCC, HBGA, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, HVQFN, HVSON, SMS PLCC(4), SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO Notes 1. For more detailed information on the BGA packages refer to the "(LF)BGA Application Note" (AN01026); order a copy from your Philips Semiconductors sales office. 2. 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". 3. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 4. 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. 5. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 6.
