Description
74HC145 is BCD to Decimal Decoder / Driver ( O.D Output ).
The 74HC145 is a specific type of integrated circuit (IC) that is designed to function as an encoder or a priority encoder. It belongs to the 74HC series of logic ICs and is widely used in digital electronics for various encoding applications.
This IC is a 4-to-16 line encoder, which means it can take up to four binary inputs (A, B, C, and D) and convert them into a 4-bit binary code that represents the active input line. The encoder has 16 output pins (Y0 to Y15) corresponding to each of the 16 possible input combinations. When one of the input lines is active (low), the output pins will represent the binary code equivalent to the active input line.
