The 74LS393 is a low-power Schottky TTL IC with two independent 4-bit binary ripple counters. Each counter has its own clock input (falling-edge triggered) and an asynchronous clear input, and the two halves can be chained into an 8-bit (divide-by-256) counter. It is used for frequency division and simple address and timing counters. It runs from a 5 V supply. It comes in a 14-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 (SGS T74LS393B1 98544); only the background was cleaned to white, preserving the marking and leads.
Minimum order: 1 pc.
