Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

(V = 3.3V), 10A I max. PD CC CC the positive edge of the clock pulse. After the Clock Power down high impedance inputs and outputs Pulse input threshold voltage has been passed, the Data 24mA output drive (V = 3.0V) CC input is locked out and information present will not be Implements proprietary noise/EMI reduction circuitry transferred to the outputs until the next rising edge of the Clock Pulse input. Latch-up performance exceeds JEDEC 78 conditions ESD performance: Asynchronous Inputs: Human body model > 2000V LOW input to S (Set) sets Q to HIGH level D Machine model > 200V LOW input to C (Clear) sets Q to LOW level D Leadless Pb-Free DQFN package Clear and Set are independent of clock Simultaneous LOW on C and S makes both Q D D and Q HIGH Ordering Information Package Order Number Number Package Description 74LCX74M M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 74LCX74SJ M14D 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide (1) 74LCX74BQX MLP14A 14-Terminal Depopulated Quad Very-Thin Flat Pack No Leads (DQFN), JEDEC MO-241, 2.5 x 3.0mm 74LCX74MTC MTC14 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Note: 1.
