Common Anode Display A seven-segment LED display where the anodes of
all the LEDs are connected to the circuit supply
voltage. Each segment is illuminated by a logic LOW
at its cathode.
, Common Cathode Display A seven-segment display in which the cathodes of all
the LEDs are connected together and grounded. A
logic HIGH illuminates a segment when applied to its
anode.
Datasheet A printed specification giving details of the pin
configuration, electrical properties, and mechanical
profile of an electronic device.
De-multiplexer A circuit that uses a binary decoder to direct a digital
signal from a single source to one of several
destinations.
Design Specifications A detailed description, especially one providing
information needed to make, build, or produce
something.
Encoder A digital circuit that produces an output code
depending on which of its inputs is activated.
Exclusive-NOR (XNOR) Circuit Two-input logic circuit that produces a high output
only when the inputs are equal.
Exclusive-OR (XOR) Circuit Two-input logic circuit that produces a high output
only when the inputs are different.
Full Adder Logic circuit with three inputs and two outputs. The
inputs are a carry bit (CIN) from a previous stage, a
bit from the augend, and a bit from the addend,
respectively. The outputs are the sum bit and the
carry-out bit (COUT) produced by the addition of
the bit from the addend with the bit from the augend
and CIN.
