In electronics, glue logic is the custom logic circuitry used to interface a number of off-the-shelf integrated circuits.[1] This is often achieved using common, inexpensive 7400- or 4000-series components. In more complex cases, a programmable logic device like a CPLD or FPGA might be used. The falling price of programmable logic devices, combined with their reduced size and power consumption compared to discrete components, is making them common even for simple systems. In addition, programmable logic can be used to hide the exact function of a circuit, in order to prevent a product from being cloned or counterfeited.

The software equivalent of glue logic is called glue code.


Typical functions of glue logic include:
