Q1: Assertion (A): Even if TTL gates and CMOS gates used in a realization have the same power supply of + 5 V, suitable circuit is needed to interconnect them Reason (R): V_OH, V_OL, V_IH and V_IL of a TTL gave are respectively 2.4, 0.4, 2 and 0.8 V respectively. If supply voltage is + 5 V. V_IL and V_IH for CMOS gate for the supply voltage of + 5 V are 1.5 V and 3.5 V respectively.

A Both A and R are correct and R is correct explanation of A

B Both A and R are correct but R is not correct explanation of A

C A is true, R is false

D A is false, R is true

ANS:A - Both A and R are correct and R is correct explanation of A

Interfacing is necessary and interfacing depends on gate parameters like V_OH, V_OL, I_IH, I_IL.
