74ALS138 - 1-of-8 decoder/demultiplexer

General Description

The 74ALS138 decoder accepts three binary weighted inputs (A0, A1, A2) and when enabled, provides eight mutually exclusive, active-Low outputs (Q0

Q7).

Key Features

  • Demultiplexing capability.
  • Multiple input enable for easy expansion.
  • Ideal for memory chip select decoding.

INTEGRATED CIRCUITS 74ALS138 1-of-8 decoder/demultiplexer Product specification IC05 Data Handbook 1996 Jul 03 Philips Semiconductors Philips Semiconductors Product specification 1-of-8 decoder/demultiplexer 74ALS138 FEATURES • Demultiplexing capability • Multiple input enable for easy expansion • Ideal for memory chip select decoding DESCRIPTION The 74ALS138 decoder accepts three binary weighted inputs (A0, A1, A2) and when enabled, provides eight mutually exclusive, active-Low outputs (Q0 – Q7). The device features three Enable inputs; two active-Low (E0, E1) and one active-High (E2). Every output will be High unless E0 and E1 are Low and E2 is High.
