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.

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 Ratin
