[SOLVED] Need guide for Hfbr ic circuit !!!????

[WidElectronics]

Hi all,

Above I have attached an image of the circuit.. Any one plz guide about its operation....:?:
HFBR is a transceiver and ic name is not given...
U1F is 7414 ic- hex inverter ic...
In HFBR pin no.1-RO(receiver o/p), 2-(RE-active low), 3-DE(data enable), 4-DI(data i/p), 5-gnd,6-A/Y(it is input if DE=0, o/p if DE=1)noninverting receiver i/p or driver o/p,
7-B/Z( same as A/Y but inverting),
8-Vcc
Hoping for solution...:grin:
Thanks in advance

HFBR is a transceiver and ic name is not given...

the sound is like 6n137 ICs check the datasheet it might help you.

Thank you... bt HFBR is a transceiver... i want to know here it is used as transmitter or receiver?

 

[mohammadyou]

it depend on your schematic. I couldn't find any clue from this picture.

sorry for that...pin no. 7 and 3 are grounded... and inverter 12th pin is given ti cpld-144... this might b useful..
actually if pin no.3 grounded means 6th pin is input->hfbr is receiver...but then it is given to inverter input...thats y i am confused.... s it right??? plz...tell me

 

[mohammadyou]

same to me. does this circuit work?!!!!!!
if it does, you might made a mistake with the pins descriptions. it should be something else.

Yeah... thank you....as u say pin description is different... After searching and analysing other schematics now i come to know that ic no. is 2414.....
It has photodetector and on 6th pin it has received data.... pin no.2 is Vcc..
Again thank you for replying and guiding me....:smile:
