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 mon 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 mon bussing of the outputs. It operates over a remended VDD power supply range of 3 V to...
