SN74LS148D - 10-LINE TO 4-LINE AND 8-LINE TO 3-LINE PRIORITY ENCODERS

Download the SN74LS148D datasheet PDF (SN74147 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for 10-line to 4-line and 8-line to 3-line priority encoders.

Description

These TTL encoders feature priority decoding of the inputs to ensure that only the highest-order data line is encoded.

The ’147 and ’LS147 devices encode nine data lines to four-line (8-4-2-1) BCD.
