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 compatible inputs significantly reduce current
loading to input drivers while TTL compatible outputs offer improved
switching noise performance. A V_I 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.
