MC74LCX74 Low-Voltage CMOS Dual D-Type Flip-Flop With 5 V−Tolerant Inputs The MC74LCX74 is a high performance, dual D−type flip−flop http://onsemi.com with asynchronous clear and set inputs and complementary (O, O) outputs. It operates from a 2.3 to 3.6 V supply. High impedance TTL MARKING compatible inputs significantly reduce current loading to input drivers DIAGRAMS while TTL compatible outputs offer improved switching noise 14 performance. A VI specification of 5.5 V allows MC74LCX74 inputs SOIC−14 to be safely driven from 5.0 V devices. 14 LCX74G D SUFFIX The MC74LCX74 consists of 2 edge−triggered flip−flops with CASE 751A AWLYWW 1 individual D−type inputs. The flip−flop will store the state of 1 individual D inputs, that meet the setup and hold time requirements, on the LOW−to−HIGH Clock (CP) transition. 14 Features TSSOP−14 LCX  Designed for 2.3 V to 3.6 V VCC Operation 14 1 CDATS SEU 9F4F8IXG AL7Y(cid:2)4W(cid:2)  5.0 V Tolerant Inputs − Interface Capability With 5.0 V TTL Logic 1  LVTTL Compatible A = Assembly Location  LVCMOS Compatible L, WL = Wafer Lot  24 mA Balanced Output Sink and Source Capability Y, YY = Year  Near Zero Static Supply Current in All Three Logic States (10 (cid:2)A) WG ,o Wr (cid:2)W == PWbo−rFkr eWee Peakckage Substantially Reduces System Power Requirements (Note: Microdot may be in either location)  Latchup Performance Exceeds 500 mA  ESD Performance: Human Body Model >2000 V ORDERING INFORMATION Machine Model >200 V See detailed ordering and shipping information in the package  These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS dimensions section on page 3 of this data sheet.
