Abstract
An isolation cell clamps a signal passing from a first, powered-down power domain to a second, power-on power domain. To reduce leakage current, some of the circuits and devices are connected to a voltage supply of the first or 'from' power domain, while other circuits and devices are connected to a voltage supply of the second or 'to' power domain.
