In order to allow dual fuel operation, that is to say gas and liquid fuel, a fuel injection arrangement and an assembly are provided in which an injection conduit provides constriction to an airflow towards an outlet. In an assembly a plurality of arrangements including liquid fuel jets are arranged to such that through high angle incidents by the airflow appropriate vaporization and droplet formation is achieved for a fuel/air mixture combustible in a combustor of a turbine engine. At low liquid fuel flow rates below a pre-determined level the liquid fuel is atomised and entrained by the airflow. At high liquid fuel flow rates the fuel splash impinges upon a wash surface to develop a wash film which is again vaporised and atomised about an edge for a fuel/air mixture capable of combustion.

A state machine is configured with a phase-locked loop clock signal generator which can operate at a rate faster than an externally generated reference clock signal applied to the phase-locked loop. The output of the phase-locked loop is used to trigger registers coupled to the state machine at a selected rate to enable signals at output terminals of the state machine to be updated at a rate different than the rate of the externally generated reference clock signal.

In one embodiment, the threshold voltage of the electrostatic protection circuit is selectively raised above the power supply voltage by the inclusion of a plurality of serially connected diodes connected between the power supply voltage and a discharge reference rail. The serially connected diodes become forward biased when a voltage applied to the rail is above the power supply voltage by a voltage equal to the sum of the various voltage drops across the serially connected diodes.The various input pads of the integrated circuit are connected to an anode of an associated diode, wherein the cathode of the associated diode is connected to the discharge reference rail, rather than directly to V.sub.DD as in the prior art. The anodes of each of these diodes are also connected to the device to be protected within the integrated circuit. Thus, when a voltage applied to the input pad is approximately one diode drop above the discharge reference rail, the voltage at the input pad will be shunted to the power supply voltage generator through the serially connected diodes.
