This is the chip side of PartsMine: logic, op amps, regulators, memory, microcontrollers and the peripheral chips that sat next to vintage CPUs. Chips here are new old stock (NOS) or pulls from decommissioned equipment. Before you order, match the number, the maker's logo and the package in the listing photos against the chip on your board.
Start with the family you need: Logic ICs (74LS, 74HC and CD4000 CMOS), Amplifiers (op amps and comparators), Voltage Regulators, Power Management, Interface & Driver ICs, Analog & Signal, Memory, Microcontrollers, Microprocessors & Peripherals, Oscillators and D/A Converters.
Shopping by maker? The deepest shelves are National Semiconductor, Texas Instruments and Motorola, followed by STMicroelectronics, Maxim, Fairchild and Harris.
Tip for repair work: the family letters matter. An LS part is not an HC part, and a DIP is not an SOIC. Match the core part number, the family letters (LS, HC, HCT) and the package; maker prefixes such as SN or DM and date codes can differ.
