Glossary

Access Time:: Time between the memory receiving a new input address and the output data s becoming available in a read operation.
Active Load:: A transistor that acts as a load for another transistor.
Active Low:: The low state is the one that causes the circuit to become active rather than the high state.
Active Power Dissipation:: The power dissipation of a device under switching conditions. It differs from static power dissipation because of the large current spikes during output transitions.
ADC:: Analog-to-digital converter.
Addend:: Number to be added to another.
Alphanumeric Codes:: Codes that present numbers, letters, punctuation marks, and special characters.
Arithmetic-Logic Unit (ALU):: Digital circuit used in computers to perform various arithmetic and logic operations.
Assert:: To activate. If an input line has a bubble on it, the input can be asserted by making it low.
Astable Multivibrator:: Digital circuit that oscillates between two unstable output states.
Asynchronous Transfer:: Data transfer performed without the aid of a clock.
Augend:: Number to which the addend is added.

Bilateral Switch:: CMOS switch which acts like a single-pole, single-through switch (SPST) controlled by an input logic level.
Binary Numbers:: A number code that uses only the digits 0 and 1 to represent quantities.
Bipolar:: Having two types of charge carriers; free electrons and holes.
Bistable Multivibrator:: Name that is sometimes used to describe a flip-flop.
Bit:: An abbreviation for binary digit.
