An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open. Dimensional drawing is for reference to critical specifications defined by size measurements. Certain non-critical visual attributes, such as side castellations, reference pin shape etc. may vary. All specifications are subject to change without notice 1 2 All dimensions are in millimeters. • Enable / Disable Function OUTPUT (Pin 3) (Pin 1) ACTIVE OPEN 2 '1' Level Vih ≥ 70%Vdd ACTIVE '0' Level Vil ≤ 30%Vdd High Z FOXElectronics 5570 Enterprise Parkway Fort Myers, Florida 33905 USA +1.239.693.0099 FAX +1.239.693.1554 www.foxonline.com EMEA Tel: +44 .1283.568153 | Canada +1.888.438.2369 | Asia Hong Kong Tel: +852.2854.4285 | Japan Tel: +81.3.3374.2079 © 2013 FOX ELECTRONICS | An Integrated Device Technology, Inc. company | ISO9001:2008 Certified
