74LS153 74LS04

Description

Not gate is used as inverter : IC=74LS04. 4:1 Mux Ic:-74LS153. Lsb connect to Lsb and Msb connect to Msb. like ABC( lsb-C & msb-A). selectors(S1 & s0)- S0 is LSB & S1 is Msb. Here C connected - S0( lsb- lsb) and B connected to S1. ( as msb to msb) A is for input variation.

Procedure

  1. Connect GND Port to Pin-1 (Input) of ICBase-2 (74LS153).
  2. Connect GND Port to Pin-5 (Input) of ICBase-2 (74LS153).
  3. Connect Pin-1 (Input) of ICBase-1 (74LS04) to Input-0.
  4. Connect Pin-4 (Input) of ICBase-2 (74LS153) to Pin-2 (Output) of ICBase-1 (74LS04).
  5. Connect Input-0 to Pin-3 (Input) of ICBase-2 (74LS153).
  6. Connect VCC Port to Pin-20 (VCC) of ICBase-2 (74LS153).
  7. Connect GND Port to Pin-8 (Ground) of ICBase-2 (74LS153).
  8. Connect Input-1 to Pin-2 (Input) of ICBase-2 (74LS153).
  9. Connect Input-2 to Pin-18 (Input) of ICBase-2 (74LS153).
  10. Connect VCC Port to Pin-20 (VCC) of ICBase-1 (74LS04).
  11. Connect GND Port to Pin-7 (Ground) of ICBase-1 (74LS04).
  12. Connect Input-1 to Pin-18 (Input) of ICBase-2 (74LS153).
  13. Connect Input-2 to Pin-2 (Input) of ICBase-2 (74LS153).
  14. Connect VCC Port to Pin-6 (Input) of ICBase-2 (74LS153).
  15. Connect Output-5 to Pin-7 (Output) of ICBase-2 (74LS153).
  16. Add IC 74LS153 into ICBase-2 (74LS153).
  17. Add IC 74LS04 into ICBase-1 (74LS04).
