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. . ________________________________________________________________________________________________________ Web Site: Email: www.mysoiservices.com [email protected] 2002 4511W Published June 2002 Page 2 Honeywell Solid State Electronics Center 12001 State Highway 55 Plymouth, Minnesota 55441-4799 1-800-323-8295 HRF-AT4511 Package Outline Drawing 4.0 mm This package conforms to the LPCCTM 4 X 4 mm 16 lead body dimensions.

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. ________________________________________________________________________________________________________ Web Site: Email: www.mysoiservices.com [email protected] 2002 4511W Published June 2002 Page 3 Honeywell Solid State Electronics Center 12001 State Highway 55 Plymouth, Minnesota 55441-4799 1-800-323-8295 HRF-AT4511 Truth Table S4 0 0 0 0 0 1 1 S3 0 0 0 0 1 0 1 S2 0 0 0 1 0 0 1 S1 0 0 1 0 0 0 1 S0 0 1 0 0 0 0 1 Output Reference Input 0.5 dB 1 dB 2 dB 4 dB 8 dB 15.5 dB Operation: Data on serial input D is clocked into internal registers on the low to high transition of the Clock signal (CK). The register is sampled during the Output Enable (OE) low state and clocked into the register during the low-to-high transition Evaluation Circuit Board Honeywell's evaluation board provides an easy to use method of evaluating the RF performance of our attenuator. Simply connect power, DC and RF signals to be measuring attenuator performance in less than 10 minutes.
