1 / 8 page © Semiconductor Components Industries, LLC, 2005 January, 2005 − Rev. 5 1 Publication Order Number: MC74LCX540/D MC74LCX540 Low−Voltage CMOS Octal Buffer Flow Through Pinout With 5 V−Tolerant Inputs and Outputs (3−State, Inverting) The MC74LCX540 is a high performance, inverting octal buffer operating from a 2.3 to 3.6 V supply. This device is similar in function to the MC74LCX240, while providing flow through architecture. 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 MC74LCX540 inputs to be safely driven from 5 V devices. The MC74LCX540 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 (OE1, OE2) inputs, when HIGH, disables the outputs by placing them in a HIGH Z condition. Features • Designed for 2.3 to 3.6 V V CC Operation • 5 V Tolerant − Interface Capability With 5 V TTL Logic • Supports Live Insertion and Withdrawal • I OFF Specification Guarantees High Impedance When VCC = 0 V • LVTTL Compatible • LVCMOS Compatible • 24 mA Balanced Output Sink and Source Capability • Near Zero Static Supply Current in All Three Logic States (10 mA) Substantially Reduces System Power Requirements • Latchup Performance Exceeds 500 mA • ESD Performance: Human Body Model >2000 V Machine Model >200 V • Pb−Free Packages are Available* *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. 20 1 1 20 MARKING DIAGRAMS A = Assembly Location L, WL = Wafer Lot Y, YY = Year W, WW = Work Week SOIC−20 DW SUFFIX CASE 751D LCX540 AWLYYWW LCX 540 ALYW TSSOP−20 DT SUFFIX CASE 948E SOEIAJ−20 M SUFFIX CASE 967 74LCX540 AWLYWW 1 1 1 20 1 20 20 20 See detailed ordering and shipping information in the package dimensions section on page 3 of this data sheet.
