74LVC240A

74LVC240A Low-Voltage CMOS Octal Buffer With 5 V−Tolerant Inputs and Outputs (3−State, Inverting) The 74LVC240A is a high performance, inverting octal buffer operating from a 1.2 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 74LVC240A inputs to be safely driven from 5 V devices. The 74LVC240A is suitable for memory address driving and all TTL level bus oriented transceiver applications. Current drive capability is 24 mA at the outputs. The Output Enable (OE) input, when HIGH, disables the outputs by placing them in a HIGH Z condition. Features Designed for 1.2 V to 3.6 V VCC Operation 5 V Tolerant − Interface Capability With 5 V TTL Logic Supports Live Insertion and Withdrawal IOFF Specification Guarantees High Impedance When VCC = 0 V 24 mA Output Sink and Source Capability Near Zero Static Supply Current in All Three Logic States (10 mA) Substantially Reduces System Power Requirements ESD Performance: ♦ Human Body Model >2000 V ♦ Machine Model >200 V These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant www.onsemi.com 20 1 TSSOP−20 DT SUFFIX CASE 948E MARKING DIAGRAM 20 LVC 240A ALYWG G 1 A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package (Note: Microdot may be in either location) ORDERING INFORMATION See detailed ordering and shipping info...
