The LS161A and LS163A count modulo 16 (binary.) The LS160A and LS161A have an asynchronous Master Reset (Clear) input that overrides, and is independent of the clock and all other control inputs. The LS160A and LS162A count modulo 10 (BCD). They are edge-triggered, synchronously presettable, and cascadable MSI building blocks for counting, memory addressing, frequency division and other applications. MA) MOTOROLA SN54/74LS160A SN54/74LS161A SN54/74LS162A SN54/74LS163A BCD DECADE COUNTERSI 4-BIT BINARY COUNTERS The LS160A/161A/162A/163A are high-speed 4-bit synchronous count- ers. Further explain why common anode configuration is needed for our 7-segment display rather than the common cathode configuration. Draw the circuit connection of the decade counter in (a) and the decoder to display the count value on the 7-segment LED display.

Capture the circuit schematic and the simulated waveform (Define the simulation timings for at least one full counting cycle from 0 to 9 and back to 0.) (Hint: Use the DigClock input from the SOURCE as shown below and setup the CLK ONTIME and OFFTIME accordingly for the clock source.)

Simulate the complete counter circuit by OrCAD and PSPICE. The single-digit decade counter should be built by a cascaded synchronous binary counter (74LS163) and other basic logic gates. 5us SLK DELAY = STARTVAL = 0 OPPVAL = 1 Part List: DiClock FileStim1 FileStim 16 FileStim2 FileStim32 Filostim4 File Stim8 IAC Libraries: abc Design Cache EVAL SOURCE 2Ĥ504189) 0.800 MINI 9.10 140X551) 1102953 31.10.043) 0.32 & 56.3351 0.281610) 3.00 120/MIN E5-A32xRD 1,6 D DP BS-C323RD 1,6 A B C D E F GDP TBCDEFGDP 10 5 4 13Ī) Design a single-digit decade counter that counts from 0 to 9 and repeats.
