Overview
The HEF4043BT,652 is a quad R/S latch with 3-state outputs, manufactured by Nexperia USA Inc. This integrated circuit is part of the HEF4000 family and features a common output enable input (OE). Each latch within the IC has set (nS) and reset (nR) inputs, along with a 3-state output (nQ). When the output enable (OE) is in the LOW state, the latch outputs enter a high impedance OFF-state, without affecting the state of the latch itself. This component is designed for a wide range of applications due to its robust specifications and versatile functionality.
