What logic IC functions as 7 segment hex decoder?
A stand alone CMOS family logic IC that does what you want is the MC14495 hexadecimal to 7 segment latch/decoder LED driver IC. This chip converts 4 bit hex data into the proper output patterns to generate not only 0 – 9 but A – F on a standard 7 segment LED display. This chip has some neat features built in. It contains built in LED drivers and current limiting resistors so it can be directly connected to the 7 segment LED. It also has a pin whose logic level controls an output latch which freezes the display on the data present at the inputs when the latch is enabled.
