Use power and ground planes wherever possible. In addition, it is advisable that low ESR bypass capacitors (4.7 μF or 10 μF tantalum) be placed as close to the driver as possible. The driver should be physically located as close to the device it is driving as possible to minimize the length of the output trace. +5V Input VDD = 18V 0V 18V Output 1 Input 2 1 8,7 Output CL = 1000 pF 2 +5V Input 0V 18V Input: 100 kHz, square wave, tRISE = tFALL ≤ 10 nsec tD1 Output 0V 10% 10% 90% tR 0V 10% 10% tD1 tF 4.7 μF 0.1 μF 90% 90% tD2 tR 90% 10% Inverting Driver 90% 4 tD2 90% tF 10% Noninverting Driver FIGURE 3-1: Switching Time Test Circuit 3.2 Typical Applications VDD (4.5V - 18V) VDD (4.5V - 18V) From TTL RT TC4404 RT VOUT From TTL RIB TC4405 RIB GND GND FIGURE 3-2: Zero Crossover Current Totem-Pole Switch FIGURE 3-3: Driving Bipolar Transistors DS21418C-page 6 © 2006 Microchip Technology Inc. TC4404/TC4405 +24V 47 kΩ +12V 15V 0.1 μF 15V 0.1 μF 47 kΩ Direction (TTL Level) Speed (PWM) RT Motor RT ISENSE GND TC4469 TC4404 FIGURE 3-4: Servo Motor Control +12V +12V Switched +12V +5V +5V From TTL TC4404 GND GND Switched -12V -12V -12V FIGURE 3-5: Reach-Up and Reach-Down Driving © 2006 Microchip Technology Inc.

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.
