Find the part number and pinout diagram of various logic gates in the 7400-series, such as OR, AND, NAND, XOR, etc. The 7400-series is a popular family of digital logic devices with different subfamilies and variants.
A binary decoder is a logic circuit that converts binary information from multiple inputs to unique outputs. Learn about different types of decoders, such as 1-of-n, code translators, and binary to unary decoders, and their applications.
Examples of don't-care terms are the binary values 1010 through 1111 (10 through 15 in decimal) for a function that takes a binary-coded decimal (BCD) value, because a BCD value never takes on such values (so called pseudo-tetrades); in the pictures, the circuit computing the lower left bar of a 7-segment display can be minimized to a b + a c by an appropriate choice of circuit outputs for ...
Binary-coded decimal (BCD) is a binary encoding of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Learn about the different types of BCD, their advantages and disadvantages, and their applications in computing and electronic systems.
Double dabble is a computer science algorithm that converts binary numbers into binary-coded decimal (BCD) notation. It involves shifting, adding and incrementing the original binary value in a scratch space until the BCD representation is obtained.
In addition to the tube itself, another important consideration is the relatively high-voltage circuitry necessary to drive the tube. The original 7400 series drivers integrated circuits such as the 74141 BCD decoder driver have long since been out of production and are rarer than NOS tubes. The 74141 is still available as NOS from various web ...
4-bit computing is the use of computer architectures with 4-bit data units, such as integers or decimal digits. Learn about the origins, applications, and examples of 4-bit processors and systems.
Chen–Ho encoding is a memory-efficient alternate system of binary encoding for decimal digits.. The traditional system of binary encoding for decimal digits, known as binary-coded decimal (BCD), uses four bits to encode each digit, resulting in significant wastage of binary data bandwidth (since four bits can store 16 states and are being used to store only 10), [1] even when using packed BCD.
