Indicate the type of shift register:(a) into which a complete binary number can be loaded in one operation and then shifted out onebit at a time;(b) into which data can be entered only one bit at a time but have all data bits available as outputs;(c) in which we have access to only the leftmost or rightmost flip-flop.Table 11.16Commonly used IC counters and registers belonging to the TTL, CMOS and ECL logic families.Type Function Logicnumberfamily7490 Decade counter TTL7491 Eight-bit shift register (serial-in/serial-out) TTL7493 Four-bit binary counter TTL74160 BCD decade counter with asynchronous CLEAR TTL74161 Four-bit binary counter with asynchronous CLEAR TTL74162 BCD decade counter with synchronous CLEAR TTL74163 Four-bit binary counter with synchronous CLEAR TTL74164 Eight-bit shift register (serial-in/parallel-out) TTL74165 Eight-bit shift register (parallel-in/serial-out)74166 Eight-bit shift register (parallel-in/serial-out) TTL74178 Four-bit parallel access shift register TTL74190 Presettable BCD decade UP/DOWN counter TTL74191 Presettable four-bit binary UP/DOWN counter TTL74192 Presettable BCD decade UP/DOWN counter TTL74193 Presettable four-bit binary UP/DOWN counter TTL74194 Four-bit right/left universal shift register TTL74198 Eight-bit universal shift register (parallel-in/parallel-out bidirectional) TTL74199 Eight-bit universal shift register (parallel-in/parallel-out bidirectional) TTL74290 Decade counter TTL74293 Four-bit binary counter TTL74390 Dual decade counter TTL74393 Dual four-bit binary counter TTL4014 B Eight-bit static shift register CMOS(synchronous parallel or serial-in/serial-out)4015 B Dual four-bit static shift register CMOS(serial-in/parallel-out)4017 B Five-stage Johnson counter CMOS4021 B Eght-bit static shift register CMOS(asynchronous parallel-in or synchronous serial-in/serial-out)4029 B Synchronous presettable four-bit UP/DOWN counter CMOS4035 B Four-bit universal shift register CMOS40160 B Decade counter with asynchronous CLEAR CMOS40161 B Binary counter with asynchronous CLEAR CMOS40162 B Decade counter CMOS40163 B Binary Counter CMOS40192 B Presettable BCD UP/DOWN counter CMOS40193 B Presettable Binary UP/DOWN counter CMOS4510 B Presettable UP/DOWN BCD counter CMOS
