Product Overview 74LVC540: Low Voltage CMOS Octal Buffer Flow Through Pinout For complete documentation, see the data sheet Product Description The 74LVC540A is a high performance, inverting octal buffer operating from a 1.2 to 3.6V 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 5.5V allows 74LVC540A inputs to be safely driven from 5V devices. The 74LVC540A 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(OE1bar, OE2bar) inputs, when HIGH, disables the outputs by placing them in a HIGH Z condition.
