The CGS405 comprises
four boolean logic elements:-
- NOT - this is a basic inverter. If
you apply a LOW (e.g. a gate output in its
OFF state) it will give a HIGH (gate ON)
output, and vice versa.
-
The OR gate has two inputs, and gives a HIGH
whenever one or both inputs
are HIGH.
- The
AND gate has two inputs, and gives a HIGH
only when both inputs are HIGH.
- The
Exclusive OR gate (XOR), gives a LOW when
both inputs are within 1.2 volts of each
other, and a HIGH when they are not.
The
OR, AND and XOR also offer inverted outputs,
giving the option of using them as NOR, NAND
and XNOR gates. Unlike the Analog Logic
module, these are for processing gate, trigger
and clock signals, although the XOR gate can
accept linear inputs as well.

In this table '0' represents
any voltage below ~1.5V while '1'
represents any voltage above ~1.5V.

In
builds where you are replacing the CGS36 and
do not have an additional 1" slot, the CGS405
can be stacked
on top of the CGS336.
