The ED132 is a Boolean Logic module comprising six logic elements:- AND, NAND, OR, NOR, XOR and XNOR.

A fourth logic element provides a NOT or invert function.All logic elements are generated using dual-input NAND gates (4011).

Inputs must swing either side of +2.5V and all outputs will swing between 0V and +5V.

LED indicators reflect the state of the non-inverted outputs i.e. AND, OR and XOR. By implication the NOT LED indicates the status of the input.

All input pairs are normalised to the AND/NAND element (1A -> 2A, 1A -> 3A and 1B -> 2B, 1B -> 3B) and allows a single pair of patched inputs to generate all 6 logic outputs.
