Data Sheets and Specifications

DATA SHEETS AND SPECIFICATIONS

The manufacturers of real-world devices provide data sheets that specify the devices’ logical and electrical characteristics. The electrical specifications portion of a minimal data sheet for a simple CMOS device, the 54/74HC00 quadruple NAND gate, is shown in Table.1. Different manufacturers typically specify additional parameters, and they may vary in how they specify even the “standard” parameters shown in the table.

They usually also show the test circuits and waveforms that they use to define various parameters, as shown in Fig.1, which contains information for some parameters in addition to those used with the 54/74HC00. As a logic designer, we need this knowledge to create reliable and robust real-world circuits and systems.
