MC74LVX138 3-to-8 Line Decoder With 5V-Tolerant Inputs The MC74LVX138 is an advanced high speed CMOS 3-to-8 line decoder. The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems. When the device is enabled, three Binary Select inputs (A0 - A2) determine which one of the outputs (O0 - O7) will go Low. When enable input E3 is held Low or either E2 or E1 is held High, decoding function is inhibited and all outputs go high. E3, E2, and E1 inputs are provided to ease cascade connection and for use as an address decoder for memory systems. http://onsemi.com MARKING DIAGRAMS 16 SOIC-16 D SUFFIX CASE 751B Features * * * * * * * * * LVX138G AWLYWW 1 High Speed: tPD = 5.5 ns (Typ) at VCC = 3.3 V Low Power Dissipation: ICC = 4 mA (Max) at TA = 25 C Power Down Protection Provided on Inputs Balanced Propagation Delays Low Noise: VOLP = 0.5 V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300 mA ESD Performance: Human Body Model > 2000 V; Machine Model > 200 V These Devices are Pb-Free and are RoHS Compliant 16 LVX 138 ALYWG G TSSOP-16 DT SUFFIX CASE 948F 1 16 SOEIAJ-16 M SUFFIX CASE 966 LVX138 ALYWG 1 LVX138 A WL, L Y WW, W G or G = Specific Device Code = Assembly Location = Wafer Lot = Year = Work Week = Pb-Free Package (Note: Microdot may be in either location) ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 3 of this data sheet.
