HEF4511BT,652

The HEF4511BT,652 is an Integrated Circuit (IC) component manufactured by NXP Semiconductors. It is a BCD to 7-segment latch/decoder/driver IC with four inputs and seven outputs. The component is commonly used in various electronic devices such as digital displays, scoreboards, and electronic timers. Key Features of HEF4511BT,652: 1. BCD to 7-Segment Conversion: The IC has four BCD (Binary Coded Decimal) inputs (A, B, C, D) that can be used to input a 4-bit binary code. The IC converts the BCD code into a corresponding 7-segment output that can be used to drive a 7-segment display. 2. Latch and Decoder Functionality: The IC incorporates a latch, enabling it to store the input BCD code while decoding it into a corresponding 7-segment output. This ensures stability and eliminates glitches during the conversion process. 3. Built-in Display Driver: The component includes output pins (OUT a-g) that can directly drive a 7-segment LED or LCD display without requiring additional external driver circuitry. Each output corresponds to a specific segment on the display. 4. Active-Low Outputs: The outputs of the IC are active-low, meaning that a low voltage level is required to turn on a particular LED segment. This simplifies the interface between the IC and the display
