4022 – divide-by-8 counter with 8 decoded outputs, CMOS 4000B, DIP-16 (generic)

The 4022 is a 4000B-series CMOS IC containing a Johnson counter that divides by 8 and has eight decoded outputs, one of which is high at a time. It has clock, clock enable and reset inputs plus a carry-out output for cascading; it is the 8-stage sibling of the 4017 (divide-by-10) and is used in sequencers and chasers. Like most 4000B parts it works over a wide supply range (typically 3–15 V for the B series); check the limits in the datasheet for the specific manufacturer. 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 (National CD4022BCN / MM5622BN); only the background was cleaned to white, preserving the marking and leads.

Minimum order: 1 pc.
