You're currently on: Catalog » DIY Kits, Electronics and ICs » 4044 – quad NAND R/S latch with 3-state outputs, CMOS 4000B, DIP-16 (generic)
The 4044 is a 4000B-series CMOS IC with four independent set/reset latches built from cross-coupled NAND gates (active-low S and R inputs). All four outputs are 3-state and controlled by a common enable input, so the device can share a data bus. Typical uses include switch debouncing and simple storage. 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 (SGS HCF4044BE 98601Y); only the background was cleaned to white, preserving the marking and leads.
Minimum order: 1 pc.
