SN74LS47N Texas Instruments Encoder, Decoder, Multiplexer u. Available schematic symbol, footprint and datasheet specification. Wherever did you come up with that quaint notion? You also need to connect the other inputs to a logic high or a logic low.

Read the datasheet to find out which way they need to go. Читайте отзывы покупателей и рейтинги клиентов на Sn74ls47n. In the photo, it looks like you have LEDs in series with the pull-down resistors. The voltage drop across a red LED can be around 1. V, even at low current. TTL inputs need to be pulled to 0. V or below for a valid logic zero.
