Description
The IH401A is made up of 4 monolithically constructed
combinations of varacitor type diode and a N-Channel JFET.
The JFET itself is very similar to the popular 2N4391, and
the driver diode is specially designed, such that its
capacitance is a strong function of the voltage across it. The
driver diode is electrically in series with the gate of the
N-Channel FET and simulates a back-to-back diode
structure. This structure is needed to prevent forward biasing
the source-to-gate or drain-to-gate junctions of the JFET
when used in switching applications.
Previous applications of JFETs required the addition of
diodes, in series with the gate, and then perhaps a gate-to-
source referral resistor or a capacitor in parallel with the
diode; therefore, at least 3 components were required to
perform the switch function. The IH401A does this same job
in one component (with a great deal better performance
characteristics).
Like a standard JFET, the practically perform a solid state
switch function translator should be added to drive the diode.
This translator takes the TTL levels and converts them to
voltages required to drive the diode/FET system (typically a
0V to -15V translation and a 3V to +15V shift). With
