Description:

The CD4043BE (often labeled as CD40430E in some catalogs) is a quad S-R (Set-Reset) latch IC with 3-state outputs, built using CMOS technology. It’s part of the 4000-series logic family and is designed for applications requiring memory storage, signal synchronization, or control logic. Each latch in the chip operates independently and features a standard NOR gate configuration, making it ideal for use in digital systems where low power consumption and high noise immunity are essential.
