Description
Pin Assignments
The 74AHC138 is an advanced high speed CMOS device.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 remaining seven being high.There are two active LOW enable inputs E1 and E2, and one active HIGH enable input E3. The disabled device state results in all outputs being high.The enable state occurs with E 1 and E 2 asserted low and E3 asserted high.The multiple enable lines allow fo
