General Description
HD74HC148 encodes eight data lines to three-line (4-2-1) binary (octal).
Cascading circuitry (enable input EI and enable output EO) is provided to allow octal expansion without the need for external circuitry.
The data inputs and outputs are active at the low logic level.
Key Features
