Philips Semiconductors 74HC/HCT4511 BCD to 7-Segment Latch/Decoder/Driver Datasheet
The 74HC/HCT4511 is a high-speed Si-gate CMOS device designed as a BCD to 7-segment latch/decoder/driver. It features four address inputs, an active LOW latch enable input, an active LOW ripple blanking input, and an active LOW lamp test input. The device drives common cathode LED displays with a guaranteed 10 mA drive capability per output.

Questions answered in these manuals
What is the function of the LT input?
When LT is LOW, all segment outputs are HIGH regardless of other inputs.
From: Philips Semiconductors 74HC/HCT4511 BCD to 7-Segment Latch/Decoder/Driver Datasheet
What happens when the BI input is LOW?
A LOW on BI forces all segment outputs LOW to blank the display.

What does the LT pin do?
LT is the lamp‑test input; when it is LOW, all segment outputs go HIGH regardless of other inputs.
