The 74LS193 is a low-power Schottky TTL IC containing a synchronous 4-bit binary counter that counts up or down via separate clock inputs. It can be preset through four data inputs (load) and reset with a clear input, and its carry and borrow outputs make cascading several devices easy. The decade version is the 74LS192. It runs from a 5 V supply. 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 (ST T74LS193B1 98923); only the background was cleaned to white, preserving the marking and leads.
Minimum order: 1 pc.
