MC74LCX14 Low Voltage CMOS Hex Schmitt Inverter With 5 V-Tolerant Inputs The MC74LCX14 is a high performance hex inverter with http://onsemi.com Schmitt−Trigger inputs operating from a 2.3 to 3.6 V supply. High impedance TTL compatible inputs significantly reduce current MARKING loading to input drivers, while TTL compatible outputs offer improved DIAGRAMS switching noise performance. A VI specification of 5.5 V allows MC74LCX14 inputs to be safely driven from 5.0 V devices. 14 Pin configuration and function are the same as the MC74LCX04, SOIC−14 LCX14G 14 but the inputs have hysteresis and, with its Schmitt trigger function, D SUFFIX AWLYWW CASE 751A the LCX14 can be used as a line receiver which will receive slow input 1 signals. 1 Features 14  Designed for 2.3 V to 3.6 V V Operation CC TSSOP−14 LCX  5.0 V Tolerant Inputs − Interface Capability with 5.0 V TTL Logic 14 DT SUFFIX 14  LVTTL Compatible 1 CASE 948G ALY(cid:2)W(cid:2) 1  LVCMOS Compatible  24 mA Balanced Output Sink and Source Capability A = Assembly Location L, WL = Wafer Lot  Near Zero Static Supply Current (10 (cid:2)A) Substantially Reduces Y, YY = Year System Power Requirements W, WW = Work Week G or (cid:2) = Pb−Free Package  Latchup Performance Exceeds 500 mA (Note: Microdot may be in either location)  Current Drive Capability is 24 mA at Source/Sink  Pin and Function Compatible with Other Standard Logic Families ORDERING INFORMATION  ESD Performance: Human Body Model >2000 V See detailed ordering and shipping information in the package Machine Model >100 V dimensions section on page 4 of this data sheet.  Chip Complexity: 41 Equivalent Gates  These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant  Semiconductor Components Industries, LLC, 2012 1 Publication Order Number: October, 2012 − Rev. 8 MC74LCX14/D
