Question No. 1                                                                                                          

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

V_CC = 5.0V                                                          I_CCH = 19 mA

I_CCL = 35 mAt_PLH = 4 ns

t_PHL = 5 nsV_OH = 2.7 V

V_IH = 2 V                                                              V_IL = 0.8 V

V_OL = 0.5 V

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