Product Description
The Honeywell HRF-AT4510 is a 5-bit digital
attenuator that is ideal for use in broadband
communication system applications that require
accuracy, speed and low power consumption. The
HRF-AT4510 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-AT4510 is immune to latch-up.
ESD Protection: Although the HRF-AT4510 contains ESD protection circuitry on all digital inputs, conventional precautions should
be taken to ensure that the Absolute Maximum Ratings are not exceeded.
