MC14014B, MC14021B 8-Bit Static Shift Register The MC14014B and MC14021B 8bit static shift registers are constructed with MOS Pchannel and Nchannel enhancement mode devices in a single monolithic structure. These shift registers find primary use in paralleltoserial data conversion, synchronous and asynchronous parallel input, serial output data queueing and other general purpose MC14014B, MC14021B TRUTH TABLE SERIAL OPERATION: Q6 Q7 Q8 tClockD P/S t=n+6 t=n+7 t=n+8 S n000 n+1 1 0 1 0 n+2 0 0 0 1 0 n+3 1 0 1 0 1 X 0 Q6 Q7 Q8 PARALLEL OPERATION: Clock MC14014B MC14021B D P/S P *Q S n n XX 1 0 0 XX 1 1 1 *Q6, Q7, & Q8 are available externally X = Dont Care PIN ASSIGNMENT P8 1 16 V DD Q6 2 15 P7 Q8 3 14 P6 P4 4 13 P5 P3 5 12 Q7 P2 6 11 D S P1 7 10 C V 8 9 P/S SS LOGIC DIAGRAM P1 P2 P3 P6 P7 P8 76 5 14 15 1 9 P/S 11 D D QD QDQD QD QD S C C C C Q C Q C Q 10 CLOCK V = PIN 16 P4 = PIN 4 DD 212 3 V = PIN 8 P5 = PIN 13 SS Q6 Q7 Q8
