CD4054 4-Segment Display Driver

Contents hide

CD4054 belongs to the CD4000 IC series. The CD4054 is a display driver IC for a 4 – segment Liquid crystal display. The IC is made by using the complementary MOS (CMOS) technology. integrated with p-type and n-type enhancement mode transistors. CD4054 is always available in a 16-pin hermetically sealed dual in line IC package. The IC offers a wide variety of working voltages and is directly interfaceable with other TTL, CMOS, and NMOS devices. Each pin of the IC has static protection through I/O clamping diodes.

What is an LCD Display Driver?

LCD drivers, sometimes referred to as an LCD display driver is an integrated circuit that serves as an interface between the MPU or MCU of a system and a liquid crystal display (LCD). LCD driver ICs have stored character maps in various languages. They also contain programmable shape memory, allowing them to support user defined characters.
