1 / 9 page © Semiconductor Components Industries, LLC, 2015 October, 2015 − Rev. 0 1 Publication Order Number: 74LVC244A/D 74LVC244A Low-Voltage CMOS Octal Buffer With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting) The 74LVC244A is a high performance, non−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 74LVC244A inputs to be safely driven from 5 V devices. The 74LVC244A 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 output 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 1 20 MARKING DIAGRAM A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package LVC 244A ALYW G G TSSOP−20 DT SUFFIX CASE 948E See detailed ordering and shipping information on page 7 of this data sheet.
