CD4511BE CMOS BCD-to-seven segment latch/decoder/driver IC
The CD4511BE from Texas Instruments is a CMOS BCD-to-seven segment latch/decoder/driver IC specifically designed for driving common-cathode LED displays and other display technologies. Housed in a 16-pin PDIP package, this robust integrated circuit operates from a wide voltage range of 3V to 18V, making it suitable for various industrial, automotive, and consumer applications requiring numeric display functionality. The device combines four binary-coded decimal (BCD) inputs with a large output drive capability, enabling direct interface with seven-segment displays while incorporating built-in latch and blanking functions that enhance display stability and control in demanding electronic systems where reliable visual output is essential.
CD4511BE Key Features
This decoder/driver features a storage latch that holds the BCD data, ensuring stable display output even when input signals change, and includes lamp test and blanking inputs for display control flexibility. It provides high output source current up to 25mA, enabling direct drive of standard seven-segment displays without external transistors, and incorporates ripple-blanking functions for multi-digit display applications. The CD4511BE operates with typical power dissipation of 10μW at 5V and features full static operation with no clock requirement, while its CMOS technology provides high noise immunity and compatibility with TTL and CMOS logic levels. The device also includes over-temperature protection and is characterized for operation from -55°C to 125°C, ensuring reliable performance across extreme environmental conditions.
