Logic IC Tester

Main goal of this project was to make a logic IC tester that allows adding new tests and support for new ICs easily.

Features

• fully programmable (client-side, in python)
• designed for 5 V TTL logic, but other 5 V logic families can be tested too
• 1.7 μs (<=16-pin ICs) and 2.15 μs (>16-pin ICs) per single logic test cycle
• built-in tests for 4164 and 41256 memories (MARCH C- test in read+write, read/write and page access modes)
• built-in tests for 74121, 74122 and 74123 univibrators
• small and USB powered

Components

Project is split into three parts:

• hardware - KiCad project files (see also this pdf for schematic)
• firmware - IC tester firmware
• tool - software that controls the tester
