HEF4043B - NXP

HEF4043B Quadruple R/S latch with 3-state outputs

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 outpu.
