The 7403 is a classic standard TTL IC containing four independent 2-input NAND gates with open-collector outputs. Because the outputs are open-collector, they require external pull-up resistors to establish a high logic level, making them ideal for wired-AND logic configurations and level translation. It runs from a 5 V supply. It comes in a 14-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 7403N 7829); only the background was cleaned to white, preserving the marking and leads.
Minimum order: 1 pc.
