Wikipedia:excess-3 to decimal decoder. Inverting gates could be cascaded as a ring oscillatoruseful for purposes where high stability was not required. Often a part from a different 74x00 subfamily could be substituted " drop-in replacement " in a circuit, with the same function and pin-out yet more appropriate characteristics for an application perhaps speed or power consumptionwhich was a large part of the appeal of the 74C00 series over the competing CDB series, for example. Some most common members of the family and their functions are. PCB Designer 23 November Quad two-input OR gates. These parts are prefixed with 54 instead of 74 in the part number. The 74S family, using Schottky circuitry, uses more power than the 74, but is faster.
Quad 2-input NAND gate. Quad 2-input NOR gate. Quad 2-input AND gate.

Why is there no opencollector ORgate in the series Electrical Engineering Stack Exchange
November 25, It shares this property with the NAND gate. Wikipedia:error detection and correction EDAC. Due to the popularity of these parts, other manufacturers have released pin-to-pin compatible devices which kept the sequence number as an aid to identification of compatible parts.
The "2G" 74x2G02, dual 2-input NOR gate, LVC. The series of integrated circuits (ICs) are the most popular logic families.
InTexas Unlike the older resistor-transistor logic integrated circuits, bipolar TTL gates were unsuitable to be used as analog The quad NAND gate was the first product in the series, introduced by Texas Instruments in a military. series is an extended family of digital integrated circuits. discrete logic chips chips such as and gates and or gates as well as registers, decoders, and RAM units.Quad 2-input NOR gate; open collector outputs.

ON Semiconductor. Thus e. Some manufacturers released some equivalent CMOS circuits with a 74 prefix, for example the 74HC was a replacement for the with slightly different electrical characteristics different power supply voltage ratings, higher frequency capabilities, lower "on" resistances in analog switches, etc. Propagation delay per gate.

For more details, refer primarily to the Texas Instruments documentation mentioned in the References section. IC manufacturers continue to make a core subset of this group, but many of these part numbers are considered obsolete and no longer manufactured.

Basics and Overview of Flip Flops. Its popularity is based on the fact that any logic gate function can be created using only NAND gates. Some xxx parts, however, do not have a direct counterpart from the standard 74xxx range but deliver new functionality instead, which needs making use of the xxx series' higher pin count.
