HEF4043BT-Q100: Quad R/S latch with 3-state outputs
The HEF4043B-Q100 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).
The nR and nS inputs determine the latch output (nQ) when OE is HIGH.
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.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 3) and is suitable for use in automotive applications.
