Quad R/S latch with 3-state outputs -- HEF4043BT,652
from Nexperia

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... [See More]
