GATE EC 2006 Set 1 Q44 — Combinatorial Circuits

An $\frac{\mathrm{I}}{\mathrm{O}}$ peripheral device shown in Figure $(b)$ below is to be interfaced to an $8085$ microprocessor. To select the $\frac{\mathrm{I}}{\mathrm{O}}$ device in the $\frac{\mathrm{I}}{\mathrm{O}}$ address range $\mathrm{D} 4 \mathrm{H}-\mathrm{D} 7 \mathrm{H}$, its chip-select $(\overline{C S})$ should be connected to the output of the decoder shown in Figure $(a)$ below
