You have looked at and referenced many datasheets. Now it is your time to create one.

1. Introduction

Hard to imagine, but the standard laboratory report is not very typical of the type of writing an engineer does during the course of their work. Perhaps in a research or discovery role, or a forensic report, but much of the technical writing done by a working engineer is communicating necessary information to others.

This is especially the case for an electronic device manufacturer. The most important document for these products is the datasheet, which generally contains all of the information needed for a customer (the circuit designer) to make a decision whether the part is suitable for a particular application and how the part is operated and performs.

Labs 6 and 7 dealt with the design, construction, and measurement of two static CMOS logic gates, an inverter and a 3-input gate.

Collect your design notes and measurements and, instead of writing a standard lab report, create a datasheet for your 3-input gate.

2. Evaluation rubric

CircuitLab is great for good-looking schematics.

Section 8 Parameter Measurement Information from TI’s SN74AHCT594 datasheet is a particularly good example of clearly communicating the measurement method and the parameter definitions used in the accompanying tables.

The Analog Devices AD797 op amp datasheet also has lots of examples on the combination of figures, graphs, and text. See page 14 Settling Time and the related Figure 44 on the next page for a specific example.

This was a real product: LH0033C Damn Fast Buffer Amplifier

The following are two examples of datasheets from previous students. NOTE: the requirements were different than this assignment they would score around an 85% for this assignment.

The below are silly datasheets, but have still good form and structure:
