Overview
HEF4043B Quad R/S latch with 3-state outputs Rev.
13 — 8 December 2021 Product data sheet 1.
General description The HEF4043B 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 VDD.
