SN74HC148D - 8-LINE TO 3-LINE PRIORITY ENCODERS

Download the SN74HC148D datasheet PDF. This datasheet also covers the SN74HC148 variant, as both devices belong to the same 8-line to 3-line priority encoders family and are provided as variant models within a single manufacturer datasheet.

General Description

The SNx4HC148 is an 8-input priority encoder.

Added input enable (EI) and output enable (EO) signals allow for cascading multiple stages without added external circuitry.

Key Features

  • Wide operating voltage range of 2V to 6V.
  • Outputs can drive up to 10 LSTTL loads.
  • Low power consumption, 80-μA max ICC.
  • Typical tpd = 16ns.
  • ±4-mA output drive at 5V.
  • Low input current of 1μA max.
  • Encode eight data lines to 3-line binary (Octal) 2.
