TC426/TC427/TC428 3.0 APPLICATIONS INFORMATION 3.4 Power Dissipation The supply current vs frequency and supply current 3.1 Supply Bypassing vscapacitive load characteristic curves will aid in determining power dissipation calculations. Charging and discharging large capacitive loads quickly requires large currents. For example, charging The TC426/TC427/TC428 CMOS drivers have greatly a 1000 pF load to 18V in 25 nsec requires an 0.72A reduced quiescent DC power consumption. Maximum current from the device power supply. quiescent current is 8 mA compared to the DS0026 40 mA specification. For a 15V supply, power dissipation To ensure low supply impedance over a wide frequency is typically 40 mW. range, a parallel capacitor combination is recom- mended for supply bypassing.

Output stage power is: 3.2 Grounding Po = PDC + PAC = Vo (I ) + f C V 2 DC L S The TC426 and TC428 contain inverting drivers. Where: Ground potential drops developed in common ground impedances from input to output will appear as Vo = DC output voltage negative feedback and degrade switching speed I = DC output load current DC characteristics. f = Switching frequency Individual ground returns for the input and output Vs = Supply voltage circuits or a ground plane should be used.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
