HD74HC148FPEL

Manufacturer Part Number
HD74HC148FPEL
Description
Manufacturer
Renesas Electronics Corporation.
Datasheet
HD74HC148
8-to-3-line Octal Priority Encoder
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.
