Overview

HEF4043B Quad R/S latch with 3-state outputs Rev.
10 — 18 November 2011 Product data sheet 1.
General description The HEF4043B is a quad R/S latch with 3-state outputs with a common output enable input (OE).
Each latch has an active HIGH set input (1S to 4S), an active HIGH reset input (1R to 4R) and an active HIGH 3-state output (1Q to 4Q).
When OE is HIGH, the latch output (nQ) is determined by the nR and nS inputs as shown in Table 3.
When OE is LOW, the latch outputs are in the high impedance OFF-state.
OE does not affect the state of the latch.
The high impedance off-state feature allows common bussing of the outputs.
It operates over a recommended VDD power supply range of 3 V to 15...
