The 7442 is a classic standard TTL IC containing a BCD-to-decimal (1-of-10) decoder. It decodes a 4-bit binary-coded decimal (BCD) input to one of ten mutually exclusive, active-low decimal outputs. It can also be used as a 1-of-8 decoder or demultiplexer by utilizing the fourth input as a strobe. It runs from a 5 V supply. It comes in a 16-pin plastic DIP.
Condition: mixed surplus lot, untested. The bag may contain used (pulled) ICs of the same type from different manufacturers, so marking and date code vary. The photo shows one chip from this lot (Signetics 7442N 8124); only the background was cleaned to white, preserving the marking and leads.
Minimum order: 1 pc.
