  The observation of hysteresis in the dynamics of a third-order autonomous
chaotic system namely, the {\it{Chua's}} circuit has been reported recently
\cite{Gomes2023}. In the present work, we make a detailed study on the
emergence of dynamical hysteresis in a simple second-order non-autonomous
chaotic system namely, the {\it{Murali-Lakshmanan-Chua }} (MLC) circuit. The
experimental realization of chaotic hysteresis is further validated by
numerical simulation and analytical solutions. The presence of chaotic
hysteresis in a second-order non-autonomous electronic circuit is reported for
the first time. Multistable regions are observed in the dynamics of MLC with
constant bias.
