* three Enable inputs, two active LOW (E1, E2) and one active HIGH (E3). All outputs will be HIGH unless E1 and E2 are LOW and E3 is HIGH. This multiple enable function allows easy parallel ex- pansion of the device to a 1-of-32 (5 lines to 32 lines) decoder with just four LS138s and one inverter. (S
