How to convert binary datatype to datetime using stored procedure?

i want to covert binary datatype to datetime using stored procedure and parameters

i create the following stored procedure but it dosen't return correct value

create proc Binary_to_DateTime
(
@mydate_bin binary
)
as begin
SELECT CAST(@mydate_bin AS DATETIME)
end

when execute this proc using this binnary value (0x0000000000000000000000000000000000000000000000008C3000000000)

exec Binary_to_DateTime 0x0000000000000000000000000000000000000000000000008C3000000000

it returns 1900-01-01 00:00:00.000 which is not correct

the correct value is 1998-04-05 00:00:00.000

How to make it return the correct value?
