How does the IC 74926 work?

[kkak52]

any links to its proper tutorial?
what r the conditions for resetting, displaying the latch value etc??
i give reset only for s short time, but it keeps on resetting...

Can you confirm that 74926 number, I cannot trace it.

Do you have a datasheet or link,?

Hi Kkak52,

You have to add pull-down resistors at the reset, latch and
diplay select inputs.
Open inputs are never a good idea when designing with
(digital) circuits, especially when they are CMOS.

Here's the datasheet:
