SN74HC148D

The SN74HC148D from Texas Instruments is an 8-line to 3-line priority encoder integrated circuit. This device is designed to encode eight data lines into a 3-line binary output, facilitating N-Bit encoding and code conversion tasks.

Key features include a wide operating voltage range from 2V to 6V, supporting flexible power supply designs. The encoder offers low power consumption with a maximum ICC of 80 μA and a typical propagation delay of 16 ns. Its outputs can drive up to 10 LSTTL loads, and it provides ±4 mA output drive at 5V. The input current is kept low at a maximum of 1 μA.

Designed for surface mount applications, the SN74HC148D comes in a 16-SOIC package with dimensions of 9.90 mm × 3.90 mm. It operates within an ambient temperature range of -40°C to 85°C, making it suitable for various industrial environments. The device features added input enable (EI) and output enable (EO) signals, which allow for easy cascading of multiple stages without requiring additional external circuitry.

This priority encoder is ideal for applications requiring efficient data encoding and conversion, such as in control systems, data acquisition, and digital signal processing where space and power efficiency are critical.
