The 74HCT138 is a high speed CMOS device that is designed to be pin compatable with 74LS low power Schottky types. Pin Assignments The device accepts a three bit binary weighted address on input pins A0, A1 and A2 and when enabled will produce one active low output with the remaing seven being high. There are two active LOW enable inputs E1 and E2, and on.
