Look up the IC data sheets, and use maximum values to determine P D (avg) and t
Question:
Look up the IC data sheets, and use maximum values to determine PD(avg) and tpd(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.
