SN74LS148DR Description

Short technical summary and product information.

The SN74LS148DR is a TTL priority encoder manufactured by Texas Instruments. This device encodes eight data lines into a three-line binary (octal) output. It features priority decoding, ensuring that only the highest-order data line is encoded. The inputs and outputs are active at the low logic level, and all inputs are buffered.

 

Designed for applications such as N-Bit Encoding and Code Converters, the SN74LS148DR operates within a voltage range of 4.75V to 5.25V. It has a typical quiescent current of 400µA and an output current of 8mA. The operating temperature range is from 0°C to 70°C.

 

This component is supplied in a 16-SOIC surface mount package. The package dimensions are 16-SOIC (0.154", 3.90mm Width). It is available on tape and reel with a standard quantity of 2500 units.

 

Cascading circuitry, including an enable input (E1) and enable output (E0), is provided for octal expansion without external components. The '148 and 'LS148 series encode eight data lines to three-line (4-2-1) binary (octal).
