RELIANCE 瑞联 DBU-400 系统模块

系统模块是一个DEC模块化数字逻辑系列，在后来的FLIPCHIP之前。它们通过沿一个边缘的一组22个镀金离散引脚连接到它们插入的单元。

他们使用晶体管逆变器电路，使晶体管饱和运行，以避免依赖严格的公差；他们使用-3V和0V作为逻辑电平。它们旨在用于原型制作和生产，包括旨在避免损坏的设计特征。他们提供设计建议，包括装载规则和接线说明。

它们有多种兼容的速度线可供选择：

4000系列：第二个系列，名义上为500KHz，但有些为1MHz

1000系列：原始系列，标称5MHz

6000系列：更高的速度，标称10Mhz

8000系列：非常高的速度，标称30MHz

The system module was a DEC modular digital logic family that preceded the later FLIPCHIP. They are connected to the unit into which they are inserted by a set of 22 gold-plated discrete pins along one edge.

They use transistor inverter circuits that saturate the transistors to avoid relying on tight tolerances; They use -3V and 0V as logic levels. They are intended for prototyping and production and include design features designed to avoid damage. They provide design advice, including loading rules and wiring instructions.

They are available in a variety of compatible speed lines:

4000 Series: The second series, nominally 500KHz, but some are 1MHz

1000 Series: Original series, nominal 5MHz

6000 Series: Higher speed, nominal 10Mhz

8000 Series: Very high speed, nominal 30MHz
