ISL28915_14 Datasheet, PDF (9/10 Pages) Intersil Corporation – Nano Power, Push/Pull Output Comparator

ISL28915
In the disabled state (output in a high impedance state), the
supply current is reduced to a typical of only 0.25nA. By disabling
the devices, multiple parts can be connected together as a MUX.
In this configuration, the outputs are tied together in parallel and
a channel can be selected by the EN pin. The EN pin should never
be left floating. The EN pin should be connected directly to the V+
supply when not in use.
Proper Layout Maximizes Performance
To achieve the maximum performance of the high input
impedance, care should be taken in the circuit board layout. The
PC board surface must remain clean and free of moisture to
avoid leakage currents between adjacent traces. Surface coating
of the circuit board will reduce surface moisture and provide a
humidity barrier, reducing parasitic resistance on the board.
When input leakage current is a concern, the use of guard rings
around the comparator inputs will further reduce leakage
currents.
