HEF4044BP Datasheet PDF - NXP

●The HEF4044BP is a quad R/S Latch with 3-state outputs and a common 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 to 15V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS or another input.

● Fully static operation

● Standardized symmetrical output characteristics

● Complies with JEDEC standard JESD 13-B
