40193 – presettable 4-bit binary up/down counter, CMOS 4000B, DIP-16 (generic)

The 40193 is a 4000B-series CMOS IC containing a synchronous 4-bit binary counter that can count both up and down via separate clock inputs. It can be preset through four data inputs (load) and cleared (reset), and its carry and borrow outputs make cascading several devices easy. The pinout matches the TTL 74193. Like most 4000-series parts it works over a wide supply range; check the limits in the datasheet for the specific manufacturer and series. 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 (RCA CD40193BE 901); only the background was cleaned to white, preserving the marking and leads.

Minimum order: 1 pc.
