74LVC540A Datasheet Low-voltage CMOS Octal Buffer

Manufacturer: onsemi

Overview: 74LVC540A Product Preview Low-Voltage CMOS Octal Buffer Flow Through Pinout With 5 V−Tolerant Inputs and Outputs (3−State, Inverting) The 74LVC540A is a high performance, inverting octal buffer operating from a 1.2 to 3.6 V supply. This device is similar in function to the MC74LCX240, while providing flow through architecture. High impedance TTL patible inputs significantly reduce current loading to input drivers while TTL patible outputs offer improved switching noise performance. A VI specification of 5.5 V allows 74LVC540A inputs to be safely driven from 5 V 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 (OE1, OE2) inputs, when HIGH, disables the outputs by placing them in a HIGH Z condition.
