Description
The HD74AC138/HD74ACT138 is a high-speed 1-of-8 decoder/demultiplexer. This device is ideally suited for high-
speed bipolar memory chip select address decoding. The multiple input enables allow parallel expansion to a 1-of-24
decoder using just three HD74AC138/HD74ACT138 devices or a 1-of-32 decoder using four
HD74AC138/HD74ACT138 devices and one inverter.

Functional Description
The HD74AC138/HD74ACT138 high-speed 1-of-8 decoder/demultiplexer accepts three binary weighted inputs (A0, A1,
A2) and, when enabled, provides eight mutually exclusive active-LOW outputs (O0 to O7). The
HD74AC138/HD74ACT138 features 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 enabled function allows easy parallel
expansion of the device to a 1-of-32 (5 lines to 32 lines) decoder with just four HD74AC138/HD74ACT138 devices
and one inverter (See Figure a). The HD74AC138/HD74ACT138 can be used as an 8-output demultiplexer by using
one of the active Low Enable inputs as the data input and the other Enable inputs as strobes. The Enables inputs which
are not used must be permanently tied to their appropriate active-High or active-Low state.
