I tried to design a circuit using 7447A IC
the 3 connections - LT, RBI and RBO are in active low. I am not able to get valid output. What should be the inputs to these 3 connections to get a valid ouptut?
I have not been able to get any help regarding this on the net. They all talk of 7447 with 16 pins. in 7447A, Vcc and GND pins are missing. Ignoring them also, if i attach low input to above mentioed 3 connections(since Vcc is connectd tot them in active high), then also my output is not produced as desired.
Please help on this.
Check out the datasheet: http://www.ti.com/lit/ds/sdls111/sdls111.pdf
BI / RBI must be high for "normal" operation, also the outputs are open-collector, so pull-ups will be needed at the outputs to detect any function.
