In the 74xx series we have ICs from many different manufacturers including: MMI, Signetics, Motorola, TI, Hitachi, National Semiconductor, Fairchild, Mitsubishi, AMD, Harris, SGS, ECG, TCG, NTE and ITT.
Date codes are available from early 1972 to present.
Please add a note to your order if you are wanting a specific date code or manufacturer. If we have it, we'll ship it, otherwise the chips are pulled at random from the storage trays. Thank you.
Make sure you are replacing the chip with the correct kind! Substituting 74LS logic for a 74F won't always work - It depends on the timing in the circuit. When in doubt, stick with the exact one the schematic calls for.
As always, feel free to drop us a note if you are looking for something we do not have in stock.
