8.2.2 Detailed Design Procedure

SN74LVC08A contains four AND gates in one package which can be used for individual AND function or to implement complex Boolean logic. Figure 8-1 shows an example of implementing 3input AND function. AB are inputs for AND gate which are connected to another AND gate. Z= A × B × C. SN74LVC08A support high drive current of 24 mA which can be used to drive LEDs of even Drive low current signal FETs, an example is shown in Figure 8-1 TI recommends to use a series resistance to limit the current. If VCC is 3 V, and LED current should be 10 mA, and the forward-voltage of LED is 2.5 V, then R as shown in Figure 8-1 is calculated using Equation 1:

Equation 1. R = (VCC – VLED) / I
R = (3 – 2.5) / 0.01 = 50 Ω
