(Note 2) Operation of this Device beyond any of these parameters may cause permanent damage. Latch-Up: Unlike conventional CMOS digital attenuators, Honeywell's HRF-AT4511 is immune to latch-up. ESD Protection: Although the HRF-AT4511 contains ESD protection circuitry on all digital inputs, conventional precautions should be taken to ensure that the Absolute Maximum Ratings are not exceeded. . ________________________________________________________________________________________________________

Serial Data Load
Serial data is shifted into the register on the rising edge of clock, MSB first. The state of "OE" will not affect the shifting of data. The rising edge of the "OE" signal will be the clock for the transfer of shifted data. Latched new data occurs one prop delay after the rising edge of "OE". See the Electrical Spec Table for AC parameters.
