HEF4043B-Q100 Quad R/S latch with 3-state outputs Rev. 3 8 December 2021 Product data sheet 1. General description The HEF4043B-Q100 is a quad R/S latch with 3-state outputs and common output enable input (OE). Each latch has set (nS), and reset (nR) inputs and a 3-state output (nQ). When OE is LOW, the latch outputs are in the high impedance OFF-state. OE does not affect the state of the latch. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . DD This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 3) and is suitable for use in automotive applications. 2.
