4526 – programmable 4-bit binary down counter (divide-by-N), CMOS 4000B, DIP-16 (generic)

The 4526 is a 4000B-series CMOS IC containing a programmable 4-bit binary down counter. It can be preset through four data inputs and used as a divide-by-N counter; several devices can be cascaded for larger division ratios. The 4526 is the binary version of the 4522 BCD counter. Like most 4000B parts it works over a wide supply range (typically 3–15 V for the B series); check the limits in a 4526 datasheet. 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 (Toshiba TC4526BP); only the background was cleaned to white, preserving the marking and leads.

Minimum order: 1 pc.
