CD4054BE

The CD4054BE from Texas Instruments is a versatile display driver IC belonging to the CD4000 technology family. It features 4 channels and is designed to drive Liquid Crystal Displays (LCDs) with an operating voltage range of 3V to 18V. This device is suitable for applications requiring low power consumption, with a typical supply current of 3000µA.

The CD4054BE operates across a wide temperature range of -55°C to 125°C, making it suitable for various environmental conditions. Key features include an input clamp diode for protection and standard speed operation with a propagation delay greater than 50ns. The device supports on-chip logic-level conversion and provides full decoding for various input combinations, including digits 0-9, L, H, P, A, -, and blank positions.

This display driver is available in a 16-lead Dual In-line Plastic (PDIP) package with through-hole mounting. Its design facilitates ultra-low-power display operation and provides equivalent AC output drive for liquid-crystal displays without requiring an external capacitor. The CD4054BE is well-suited for general-purpose displays, calculators, meters, wall clocks, industrial control panels, and automotive dashboards.

Applications for the CD4054BE include general-purpose displays, calculators and meters, wall and table clocks, industrial control panels, portable lab instruments, panel meters, auto dashboard displays, and appliance control panels. Its ability to provide voltage doubling across the display, resulting in an effective 36V p-p drive, makes it particularly useful for driving selected display segments.
