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. ________________________________________________________________________________________________________ Web Site: Email: www.mysoiservices.com [email protected] 2004 4510W Published August 2004 Page 2 Honeywell Solid State Electronics Center 12001 State Highway 55 Plymouth, Minnesota 55441-4799 1-800-323-8295 HRF-AT4510 Package Outline Drawing This package conforms to the LPCCTM 4 x 4 mm 24 lead body dimensions.
