Assignment No. 01

Question No. 1                                                                                                          

The data sheet of a Quad two-input AND gate IC type 74LS08 specifies the propagation delayandpower supply parameters as:

VCC = 5.0V                                                          ICCH = 19 mA

ICCL = 35 mAtPLH = 4 ns

tPHL = 5 nsVOH = 2.7 V

VIH = 2 V                                                              VIL = 0.8 V

VOL = 0.5 V

  1. Determine the speed–power product specification.
  2. The HIGH state noise margin.
  3. The LOW state noise margin.

 

Question No. 2                                                                                                           10 marks
