CD4511BE & 4 Digit 7 Segment Display

CD4511BE Pinout Equivalent

1：Overview of the CD4511BE:

CD4511BE is a commonly used BCD code-to-seven-segment latch decoder driver IC, produced by companies like STMicroelectronics. It comes in a 16-pin dual in-line package (DIP-16) and converts 4-bit BCD (binary-coded decimal) codes into drive signals for seven-segment displays, allowing the display to show numbers 0-9. The chip features latching, decoding, and driving functions. When the latch control input is active, it locks the input BCD data, maintaining the display state.

74LS47:This is a commonly used BCD-seven-segment decoder that can convert 4-bit BCD codes into signals that drive seven-segment digital tubes to display. Different from CD4511BE, it drives common anode digital tubes, while CD4511BE drives common cathode digital tubes. It has a fast working speed and can be used in scenarios with high speed requirements.

74HC4511:Similar to CD4511BE in function, it is also a BCD-seven-segment latch decoder driver. It can drive common-cathode digital tubes and has latch, decoding and driving functions. It adopts CMOS technology and has low power consumption.

MC14511B:Its functionality is similar to the CD4511BE, serving as a BCD-to-seven-segment latch decoder driver that can drive common-cathode displays and includes a latching feature.Chips produced by different manufacturers may have slight differences in electrical characteristics and parameters, but generally they can be directly replaced.

HD74LS48P:It can convert 4-bit binary BCD code into seven-segment display code and is used to drive common cathode digital tubes to display numbers. It has a relatively fast working speed and can be used in high-speed digital circuits.Also without latch function. This is different from CD4511BE which has latch function
