Question

Draw the Q outputs for 74195 shift register and explain every results ep

Answer 1

As per given Function table

INPUTS OUTPUTS SHIFT SERIALI PARA, LEL CLEAR! CLOCK LOAD JKA B C D

H=High level

L=Low level

t=Transition from Low to High

a,b,c,d = Level of input given at A,B,C,D

Q_A0,Q_b0,Q_c0,Q_d0 = level of Q_a, Q_b,, Q_c, Q_d Respectively before the indicate steady state input condition were established.

Q_An,Q_bn,Q_cn,Q_dn = level of Q_a, Q_b,, Q_c, Q_d Respectively before the most recent transition of the clock.

Explanation of Result of Q Outputs:
