This section presents the available TTL 54/74 series of ICs for ready reference for logic designers. The IC numbers given here are with the reference of their functions. However, the actual IC numbers as specified by the manufacturers also indicates the exact section of the logic family they belong, though their logic functions are the same. As an example, 74LS00 indicates quad 2-input NAND gates of the low-power Schottky family, whereas 74H00 indicates quad 2-input NAND gates of high-speed TTL. Both 54 and 74 series ICs have the same functions, but the 54 series is used for military application, for the operating temperature is -55°C to + 125°C, whereas 74 series ICs are used in industrial and commercial application with a temperature range of 0°C to +85°C. The pin configuration of both series is similar.
