Description

The chips used DTL (Diode-Transistor Logic) which was a predessesor of of the TTL (Transistor-Transistor-Logic) manufactured in the late 60s. If neccesary I could provide basic data and pinout from an old Valvo databook but it might take some days to find it.

A NAND gate is a digital logic gate that implements the Boolean function NOT-AND, which is the inverse of an AND gate. The output of a NAND gate is ‘0’ only if all of its inputs are ‘1’, and it produces a ‘1’ in all other cases. In other words, if one or more inputs are ‘0’, the output will be ‘1’. NAND gates are widely used in digital circuits due to their versatility, as they can be used to implement any other type of logic gate by connecting them in a certain configuration. NAND gates are considered to be “universal gates” because they can be used to perform any logical operation by combining them in the right way.
