A printed catalog costs $3, or you can download it free from the site (you need Adobe Acrobat Reader to view it). Among their product line useful in robotics is: • Motors (DC and stepper) • Stepper motor controllers • Power MOSFETs • H-bridge ICs (including the oft-cited L293D, L297, and L298) • Atmel AVR microcontrollers • Small CCD video cameras • Tools • Solenoids and relays Product datasheets (in PDF format) are available for download for many of the specialty semiconductor products. x d V retail-general electronics 462 Stocking Up—Integrated Circuits Integrated circuits let you construct fairly complex circuits from just a couple of compo- nents. Although there are literally thousands of different ICs, some with exotic applica- tions, a small handful crops up again and again in hobby projects. You should keep the following common ICs in ready stock: • 555 timer. This is, by far, the most popular integrated circuit for hobby electronics. With just a couple of resistors and capacitors, the 555 can be made to act as a pulser, a timer, a time delay, a missing-pulse detector, and more. • LM741 op-amp. The 741 can be used for signal amplification, differentiation, integration, sample-and-hold, and a host of other useful applications. The 741 is available in a dual version, the 1458. Note that there are numerous other op-amps available, and some have design advantages over the 741. These include the LM324, LF356, and the TL082. • LM339 quad comparator. Comparators are used to compare two voltages. The output of the comparator changes depending on the voltage levels at its two inputs. The com- parator is similar to the op-amp, except that it does not use an external feedback resis- tor. You can use an op-amp as a comparator, but a better approach is to use some- thing like the 339 chip, which contains four comparators in one package. • LM386 audio amplifier. This common and versatile single-package audio amplifier can drive an ordinary 8-ohm speaker with up to a quarter of a watt. Only a couple of capac- itors are needed to complete the circuit. • ULN2003 transistor array. A transistor array is an integrated circuit containing multiple transistors. The device is commonly used to increase the current capacity of microcon- trollers and other devices that cannot provide enough juice to run large LED panels or relays. Other transistor array ICs are available, with some able to drive loads of up to 500 mA per channel. • TTL logic chips. TTL ICs are common in computer circuits and other digital applications. There are many types of TTL packages, but you won’t use more than 10 to 15 of them unless you’re heavily into electronics experimentation. Specifically, the most common and most useful TTL ICs are the 7400, 7402, 7404, 7407, 7408, 7414, 7420, 7430, 7432, 7473, 7474, 74123, 74154, 74174, 74175, 74193, 74240, 74244, 74273, and 74274. • CMOS logic chips. Because CMOS ICs require less power to operate than the TTL vari- ety, you’ll often find them specified for use with low-power robotic and remote-control applications. Like TTL, there is a relatively small number of common packages: 4001, 4011, 4013, 4016, 4017, 4024, 4027, 4040, 4049, 4066, 4069, 4071, 4081, 4093, 4511, 4543, and 4584. Altronics Distributors Pty.

Levittown, NY 11756 USA (516) 735-3330 (516) 731-5125 retail-general electronics 466 All in the TTL Chip Family There are several families of TTL chips. The family is denoted by letter identifiers, such as 74HC193. They differ in the amount of current they consume, their speed, and their man- ufacture. The most commonly used letter identifiers are as follows: A—Advanced C—CMOS F—Fast H—High speed L—Low power S—Schottky T—TTL compatible It is common to combine letter identifiers, such as LS (low-power Schottkey), HC (high- speed CMOS), and HCT (high-speed CMOS TTL-compatible). Which one(s) to use depends on the application. If a circuit specifies a certain TTL fam- ily, be sure to use it, as the designer of the circuit may have included it for a reason. If there is no specific family mentioned, an S, LS, or HCT version will usually (note the emphasis on usually) work.
