These lines can be shared based on application requirements. The attenuator within the device is controlled with a 6 bit word, enabling the selection of 64 possible states. The highest gain state is '000000', and the lowest is '111111'. The sequence for shifting the data is as follows: Present data (MSB first), strobe clock, repeat until 6 bits have been presented and clocked, then strobe the latch enable line, which implements the state change.
