SN74LS148N Description

Short technical summary and product information.

The SN74LS148N from Texas Instruments is a TTL priority encoder designed to encode eight data lines into a three-line binary (octal) output. It features priority decoding, ensuring that only the highest-order data line is encoded. This device is suitable for applications such as N-bit encoding, code converters, and generators.

 

The encoder operates with a single supply voltage ranging from 4.75V to 5.25V and has an operating temperature range of 0°C to 70°C. The inputs and outputs are active at a low logic level. All inputs are buffered to represent one normalized Series 54LS/74LS load.

 

Packaged in a 16-PDIP through-hole configuration, the SN74LS148N is designed for easy integration into various electronic circuits. Cascading circuitry is provided for octal expansion without external components. The device is specified with a current consumption of 400µA and 8mA.

 

This component is part of the 74LS series, known for its balance of speed and power consumption. Its priority encoding capability makes it useful in systems where input prioritization is critical.
