SN54LS148J Description

Short technical summary and product information.

The SN54LS148J is a priority encoder integrated circuit manufactured by Texas Instruments. This device encodes eight data lines into three binary-weighted output lines, prioritizing higher-order inputs when multiple inputs are active. It is designed for applications such as keyboard encoding and range selection.

 

Key electrical specifications include a maximum operating frequency of 35 MHz and a typical current consumption of 20 mA at a nominal supply voltage of 5V. The operating supply voltage range is from 4.5V to 5.5V. The propagation delay is a maximum of 19 ns.

 

This component is housed in a 16-pin CDIP (Ceramic Dual In-line Package) with a R-GDIP-T JEDEC code. The package dimensions are 6.92 mm width, 19.56 mm length, 4.57 mm thickness, with a 2.54 mm pitch and a maximum height of 5.08 mm. It operates within a wide temperature range of -55°C to 125°C, making it suitable for demanding environments.

 

The SN54LS148J belongs to the LS (Low-power Schottky) technology family.
