GAL和PAL的最大差别在于GAL的输出结构可由用户定义，是一种可编程的输出结构。GAL的两种基本型号GAL16V8(20引脚)GAL20V8(24引脚)可代替树十种PAL器件，因而称为痛用可编程电路。而PAL的输出是由厂家定义好的，芯片选定后就固定了，用户无法改变。

可以理解的是，虽然本发明已以较佳实施例披露如上，然而上述实施例并非用以限定本发明。对于任何熟悉本领域的技术人员而言，在不脱离本发明技术方案范围情况下，都可利用上述揭示的技术内容对本发明技术方案做出许多可能的变动和修饰，或修改为等同变化的等效实施例。因此，凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所做的任何简单修改、等同变化及修饰，均仍属于本发明技术方案保护的范围内。
