List of 7400-series integrated circuits
open-in-new
<p> The following is a list of 7400-series digital logic integrated circuits. In the mid-1960s, the original <a href="/facts/7400-series_integrated_circuits/mDqHhWyc">7400-series</a> <a href="/facts/Integrated_circuit/fjn6vg7C">integrated circuits</a> were introduced by <a href="/facts/Texas_Instruments/88NUhuHF">Texas Instruments</a> with the prefix "SN" to create the name SN74xx. Due to the popularity of these parts, other manufacturers released pin-to-pin compatible <a href="/facts/Logic_gate/RHLulvKI">logic</a> devices and kept the 7400 sequence number as an aid to identification of compatible parts. However, other manufacturers use different prefixes and suffixes on their part numbers. </p>
