SN74HC148NSR Description

Short technical summary and product information.

The SN74HC148NSR is an 8-input priority encoder manufactured by Texas Instruments. This device is designed to encode eight data lines into a 3-line binary output. It features a wide operating voltage range from 2V to 6V and operates within a temperature range of -40°C to 85°C.

 

Key electrical characteristics include a low power consumption of 80-μA maximum ICC and a typical propagation delay of 16ns. The outputs can drive up to 10 LSTTL loads, and it offers ±4-mA output drive at 5V. The input current is a low 1μA maximum.

 

This encoder is available in a 16-SOIC package, designed for surface mounting. The SNx4HC148 series allows for cascading multiple stages without additional external circuitry, thanks to added input enable (EI) and output enable (EO) signals. Applications include N-Bit encoding and code converters and generators.
