SN74HC148N Description

Short technical summary and product information.

The SN74HC148N from Texas Instruments is an 8-input priority encoder designed for N-Bit encoding and code conversion applications. It features a wide operating voltage range from 2V to 6V, making it versatile for various designs. The device offers low power consumption with a maximum ICC of 80μA and a typical propagation delay of 16ns.

 

This encoder has added input enable (EI) and output enable (EO) signals, which facilitate cascading multiple stages without requiring additional external circuitry. The outputs can drive up to 10 LSTTL loads, and it provides ±4-mA output drive at 5V. The SN74HC148N has a low input current of 1μA maximum.

 

Packaged in a 16-PDIP, the SN74HC148N is designed for through-hole mounting. It operates within a temperature range of -40°C to 85°C. Its 1x8:3 circuit configuration and single supply voltage source make it suitable for various digital logic applications requiring efficient priority encoding.
