Objectives
At the end of this chapter, you will be able to Design circuits that use open-collector gates and decoders to drive low-voltage and low-current devices. Describe the use of open-collector decoders for memory expansion decoding. Describe the different types of peripheral drivers and transistor arrays currently available. Design high-current lamp-driver circuits. Discuss surge currents in lamp-driver circuits. Design driver circuits that use transistor arrays. Design addressable latch-driver...

Sn7407
Fig. 1-3. Typical uses of open-collector driver circuits. You should note that the maximum voltage that can be applied to the open-collector devices listed in Table 1-1 is 5.5 volts. In some applications, however, it would be useful to have open-collector devices that could handle higher voltages, and higher currents. There are other devices within the SN7400-series that have these capabilities. These open-collector devices are listed in Table 1-2. Note that all of these devices are contained...
