MC74LCX541 Low-Voltage CMOS Octal Buffer Flow Through Pinout With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting) The MC74LCX541 is a high performance, non−inverting octal buffer operating from a 2.3 to 3.6 V supply. This device is similar in function to the MC74LCX244, 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 MC74LCX541 inputs to be safely driven from 5 V devices. The MC74LCX541 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 output by placing them in a HIGH Z condition. • • • Designed for 2.3 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 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 These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant © Semiconductor Components Industries, LLC, 2012 July, 2012 − Rev. 7 MARKING DIAGRAMS 20 20 1 LCX541 AWLYYWWG SOIC−20 WB DW SUFFIX CASE 751D 1 20 20 Features • • • • • • • • http://onsemi.com 1 LCX 541 ALYW G G 1 TSSOP−20 DT SUFFIX CASE 948E A L, WL Y, YY W, WW G or G 1 = = = = = 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.
