Description:

Lot of 10x ST 74F182N look-ahead carry generator ICs in 16-pin DIP packages. The 74F182 is a high-speed TTL carry look-ahead generator for 4-bit binary adders such as the 74F181 family, providing fast carry outputs and carry propagate/generate signals. These ICs are vintage new-old-stock STMicroelectronics parts stored on anti-static foam. Leads are bright and straight with only minor storage marks; the devices have never been soldered in production.

Features & Specifications:

- Quantity per lot: 10x 74F182N ICs

- Manufacturer: STMicroelectronics

- Function: 4-bit look-ahead carry generator

- Logic family: 74F (Fast TTL)

- Package: 16-pin DIP (through-hole)

- Supply voltage: 4.75–5.25 V (nominal 5 V)

- Outputs: TTL-compatible, active-high carry and propagate/generate signals

- Typical propagation delay: a few nanoseconds (fast 74F logic)

- Condition: New old stock (NOS), untested surplus

- Stored dry on anti-static foam as shown in the photos

Applications:

- High-speed binary adders and ALUs with 74F181/74181 style devices

- Vintage computer, calculator and processor board repairs

- Educational and hobby projects exploring classic TTL arithmetic logic

- Retro-computing builds that need genuine 74F182 look-ahead carry chips

Compatibility note:

74F182N is pin- and function-compatible with standard 74182/74S182 look-ahead carry generators in 16-pin DIP format, but with Fast TTL speed and power characteristics. For drop-in replacement, confirm the pinout, 5 V TTL supply and logic levels against your schematic or datasheet. As with all vintage NOS components, test the parts in your target circuit before using them in critical or production equipment.
