The HEF4543B is a BCD to 7-segment latch/decoder/driver for liquid crystal and LED displays. It has four address inputs (D0 to D3), an active LOW latch enable input (LE), an active HIGH blanking input ...

The 74LS47 IC takes a 4-bit BCD input and drives the 7-segment display to show the corresponding decimal digit (0–9). The input switches (S1–S4) represent binary ...

Abstract: Within a digital system the information is represented by means of binary digits, also known as “bits”, and most frequently they have the meaning of numbers. In order to show the value of a ...

Many options exist to drive seven-segment LED displays, but most are limited to low output currents. The approach described here uses one 74ALS374 or 74AS374 octal latch, wired as a shift register, ...

Even if you are designing a microcontroller-based LED display system, often it may calls for a manual option to control brightness of the LED display unit. On the otherhand, if it is based on discrete ...
