SN74HC148NSR Description

Short technical summary and product information.

The SN74HC148NSR is an 8-line to 3-line priority encoder IC manufactured by Texas Instruments. It is designed to encode eight data lines into a 3-line binary output. This device features a wide operating voltage range from 2V to 6V, making it suitable for various applications.

 

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 1-μA maximum.

 

Added input enable (EI) and output enable (EO) signals allow for cascading multiple stages without external circuitry. The SN74HC148 is available in multiple package types, including PDIP, SOIC, SO, CDIP, and LCCC, with varying body sizes to accommodate different design needs. Its operating temperature range is -40°C to 85°C.
