 Welcome to Current and Voltage Parameters of Digital Circuitry. In this video, you'll learn about voltage and current parameters commonly found on a datasheet. You'll also complete a brief quiz at the end to review your knowledge. To fully understand the operation of a logic gate, you must be able to read its datasheet. The voltage and current parameters presented here will be useful in analyzing the data. Let's take a look at voltage parameters. High-level input voltage. This is the minimum voltage level required at an input for a logic 1. If the input voltage falls below this point, it will not be considered a logic 1. Low-level input voltage. This is the maximum voltage level required at an input for a logic 0. If the input voltage rises above this point, it will not be considered a logic 0. High-level output voltage. This is the minimum voltage level for a logic 1 at the output of the gate under load. Low-level output voltage. This is the maximum voltage level for a logic 0 at the output of the gate under load. Now, let's take a look at current parameters. High-level input current. This is the current that flows into an input when a logic 1 is present at the input. Low-level input current. This is the current that flows into an input when a logic 0 is present at the input. High-level output current. This is the current that flows from the output during a logic 1 output while under load. Low-level output current. This is the current that flows from the output during a logic 0 output while under load. Try to match the abbreviation on the left to the definition on the right.
