common anode driver

hello i m building a circuit consisting of a seven segment display and its driver.
i use a 7447 and a anode one
if i want to switch from TTL to CMOS , with which IC i must substitute the 7447?
is the 4511 a substitue of 7448 or 7447?


thank in advance

AFAIK there is not CMOS version; for TTL version try 74ls47

display 7 segmentos 7447 7448

There is the CMOS version of the 7447 driver, namely the 74HC47, but how are you going to get one is a different kettle of fish ..

anode driver

i think it s true, i searched a lot and was not able to find an CMOS equivalent for the 7447.
but in some docs it was written that the CD4511 can b used for both, which i find it impossible :S

Thanks for all who helped me

i think this is not wrong actually,u can use cd4511 for common annode just adding a npn transistor
