[ASK]What IC can display A-F to 7-segment LED

ajmosca25

guys, you just created a circuit a BCD 4bits Full adder but in my case i just need a 3bits-3bits addition so that i set the A4 to 0 by default...

i used 7483 for 4bits full adder and connect it to a 7447 BCD to 7-segment

A₄A₃A₂A₁ + B₄₃B₂B₁

A₄ & B₄ are set to 0

so 7 is the maximum value in one input..

my problem is when A+B = greater 9....i need to display a real letter A-F not the default light up of 7447

ex.

101(5) + 101(5) = A (bit letter A)
110(6) + 101(5) = b (small letter b)
111(7) + 101(5) = C (big letter C)
110(6) + 111(7) = d (small letter d)
111(7) + 111(7) = E (small letter E)

but in default in 7447

111(7) + 111(7) = inverted big letter F...

is there an IC which can convert 10-15 to A-F in 7segment led?

or just another IC which can configure 7447?

~help me please

Welcome to the PF.

Instead of "BCD to 7-segment display driver", try Googling Hex to 7-segment display driver...

ok, i see an IC, but im not sure if it is the IC i need...

MC14495....

im studying its datasheet right now, thx btw...

~yes i am new here in PF, thx for welcoming...Overwhelming...^_^
