Product Description
The Honeywell HRF-AT4522 is a 5-bit digital attenuator that
is ideal for use in cable communication system applications
that require accuracy, speed and low power consumption.
The HRF-AT4522 is manufactured with Honeywell's
patented Silicon On Insulator (SOI) CMOS manufacturing
technology, which provides the performance of GaAs with
the economy and integration capabilities of conventional
CMOS.

(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-AT4522 is immune to latch-up.
ESD Protection:
Although the HRF-AT4522 contains ESD protection circuitry on all digital inputs, conventional precautions should
.
be taken to ensure that the Absolute Maximum Ratings are not exceeded.

Operation:
Data on parallel input “S” pins are independently buffered and presented to the RF attenuator circuits.
"0" = CMOS Low, "1" = CMOS High.
