NXP HEF4044BT Quad R/S Latch Tri-State Outputs SO-16

The HEF4044B is a quad R/S latch with 3-state outputs, with a common output enable input (OE). Each latch has an active LOW set input (1S to 4S), an active LOW 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. 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 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.
