A logic conversion circuit device

Abstract

A logic conversion circuit device, including a logic conversion circuit, the circuit port structure of the logic conversion circuit adopts double ring protection, and an ESD input layer is added to the NMOS tube part of the circuit at the same time; there is a cooling pipe inside the cabinet, and the logic conversion circuit is just It is arranged in the cabinet body, and the inlet and outlet of the refrigerant communicated with the heat dissipation pipe are opened on the cabinet body. In addition, the cabinet body includes a front cover and front cover accessories, and the front cover is in the The location where the cabinet is opened and the location where the cabinet is covered can be pivotally connected to the cabinet. This structure improves the ESD capability of the circuit port; and increases the protection diode between the circuit power supply and ground, which also improves The ESD capability of the circuit is improved, and the defect that the front cover is often crooked in the device for closing the front cover of the prior art is avoided.

Description

technical field [0001] The invention belongs to the technical field of conversion circuits, and in particular relates to a logic conversion circuit device. Background technique [0002] In the new generation of electronic circuit design, with the introduction of low-voltage logic, the problem of input / output logic inconsistency often occurs inside the system, which increases the complexity of system design. For example, when a 1.8V digital circuit communicates with an analog circuit operating at 3.3V, it is necessary to first solve the conversion problem of the two levels, and then a logic conversion circuit device is required. With the continuous emergence of digital ICs with different operating voltages, the necessity of logic conversion circuit devices has become more prominent. Varies depending on the transfer rate. With the introduction of logic conversion measures, the number of components will inevitably be increased. In addition, with the improvement of integration...
