Product data sheet
1. General description
The 74AHC138; 74AHCT138 are high-speed Si-gate CMOS devices and are pin patible with Low power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard No. 7A.
The 74AHC138; 74AHCT138 is a 3-to-8 line decoder/demultiplexer. It accepts three binary weighted address inputs (A0, A1 and A2) and, when enabled, provides eight mutually exclusive outputs (Y0 to Y7) that are LOW when selected.
There are three enable inputs: two active LOW (E1 and E2) and one active HIGH (E3). Every output will be HIGH unless E1 and E2 are LOW and E3 is...
