The HEF4521BT,652 is a CMOS programmable BCD-to-decimal decoder/driver IC from NXP Semiconductors. This IC is capable of converting binary-coded decimal (BCD) input data into a decimal representation for driving displays or other output devices. The HEF4521BT,652 features a 4-bit BCD input, which can be programmed using external resistors to determine the decoding pattern. This IC also includes an active-low blanking input for disabling the outputs when necessary. The HEF4521BT,652 operates over a wide voltage range of 3V to 15V, making it suitable for a variety of applications. This IC is available in a SO16 package, making it easy to integrate into existing circuit designs. The HEF4521BT,652 is ideal for use in digital clock displays, frequency counters, and other applications requiring BCD-to-decimal conversion
