MC74LCX14 Low Voltage CMOS Hex Schmitt Inverter With 5 V−Tolerant Inputs The MC74LCX14 is a high performance hex inverter with Schmitt−Trigger inputs operating from a 2.3 to 3.6 V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers, while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows MC74LCX14 inputs to be safely driven from 5.0 V devices. Pin configuration and function are the same as the MC74LCX04, but the inputs have hysteresis and, with its Schmitt trigger function, the LCX14 can be used as a line receiver which will receive slow input signals. http://onsemi.com MARKING DIAGRAMS 14 SOIC−14 D SUFFIX CASE 751A 14 1 LCX14G AWLYWW 1 Features • • • • • • Designed for 2.3 V to 3.6 V VCC Operation 5.0 V Tolerant Inputs − Interface Capability with 5.0 V TTL Logic 14 14 LVTTL Compatible 1 TSSOP−14 DT SUFFIX CASE 948G LVCMOS Compatible 1 LCX 14 ALYW 24 mA Balanced Output Sink and Source Capability Near Zero Static Supply Current (10 A) Substantially Reduces System Power Requirements Latchup Performance Exceeds 500 mA • • Current Drive Capability is 24 mA at Source/Sink • Pin and Function Compatible with Other Standard Logic Families • ESD Performance: Human Body Model >2000 V Machine Model >100 V Chip Complexity: 41 Equivalent Gates 14 14 1 SOEIAJ−14 M SUFFIX CASE 965 74LCX14 ALYWG 1 A = Assembly Location L, WL = Wafer Lot Y, YY = Year W, WW = Work Week G = Pb−Free Package = Pb−Free Package (Note: Microdot may be in either location) • • Pb−Free Packages are Available* ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 4 of this data sheet. *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D.
