SN54LS147 - 10-LINE TO 4-LINE AND 8-LINE TO 3-LINE PRIORITY ENCODERS

Download the SN54LS147 datasheet PDF. This datasheet also covers the SN54147 variant, as both devices belong to the same 10-line to 4-line and 8-line to 3-line priority encoders family and are provided as variant models within a single manufacturer datasheet.

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.
