Look up the IC data sheets, and use maximum values to determine P_D(avg) and t_pd(avg) for one gate on each of the following TTL ICs. (See Example 8-2 in Section 8-3.)

(a)* 7432 

(b)* 74S32 

(c) 74LS20 

(d) 74ALS20 

(e) 74AS20

Data from Example 8-2

Refer to the data sheet for the 74ALS00 quad two-input NAND IC in Figure 8-11. Determine the maximum average power dissipation and the maximum average propagation delay of a single gate.
